NEXT CONFERENCE CALLth

The next, 7 CEOP Americas RHP and Reference Sites Teleconference is proposed to takeplace on Tuesday 12 October 2010 at 20:00 UTC. Benedict and Koudelova have the action(A1) to inform the group of the details of the next call nearer to the time of the call and tocoordinate the origination of the call (action A1a). In this context, a calendar of the dates andtimes of all the CEOP conference calls for 2010-2011 was distributed to the participants for their
future reference that is also available through the CEOP homepage at: http://monsoon.t.utokyo.ac.jp/ceop2/calls.html.

CEOP AND CEOP DATA GROUP GENERAL ISSUES(3.1a) Benedict welcomed participants on the call and appreciated the work that the Americas
RHP and reference site teams had undertaken in response to the action items from the last call.

(3.1b) Koike reiterated that a 10-Year Dataset project had been initiated in response to theclimate modeling community need of a high quality observation data of a sufficient length forevaluation of climate models under the CMIP5 project and quantification of model projections
uncertainties. This activity was proposed by the WCRP Observation and Assimilation Panelrd(WOAP) and is compliant with the CEOP commitment taken at the 3 Annual CEOP Meeting in
Melbourne in August 2009 to develop the CEOP 10-year dataset as well as with the GEWEX
post 2013 Imperatives (http://www.gewex.org/2010pangewex/Draft_Imperatives.pdf). The
WOAP suggested activity, coordinated by CEOP (T. Koike) and CMIP5 (Karl Taylor), isenvisioned as a collaborative effort of a broader observation and climate modeling communities
including GEWEX/CEOP, LandFlux-EVAL, GSWP, AsiaFlux, from the observation side. The
targeted dataset will consists of in-situ as well as satellite observations from multiple providers
including CEOP, FLUXNET, AsiaFlux, iLEAPS.
Consequently, the 10-Year Dataset project was discussed with the LandFlux-EVAL,FLUXNET, AsiaFlux, and GSWP representatives at the occasion of the HESSS2 Meeting inTokyo in June and it was agreed that a Whitepaper would have been developed and submitted
for discussion at the Pan-GEWEX meeting in August.
In this context the representatives of the sites that had been in operation since CEOP
Phase 1 were asked for kind cooperation on this task. These include Meyers (CPPA-Bondville),
Williams (SGP, ARM sites), Barr/Thompson (BERMS sites), and Horta/Araujo (LBA sites).
(3.1c) It was also reiterated that in order to demonstrate benefits of the CEOP special dataarchives it would be desirable to undergo an external review process that would clearly show thevalue that is added to the collected data including reference site and satellite observations
through the CEOP data format unification and data integration efforts. This step is necessary forassuring an adequate incentive for funding agencies to continue to support the CEOP data
activities. It was agreed that such external review was very important and reactivation of aninternational science and advisory group should be considered.
nd(3.1d) Benedict reiterated that the 2 Pan-GEWEX meeting would take place in Seattle, USA,
23 – 27 August 2010 (http://www.gewex.org/2010pangewex/home.html). The Pan-GEWEX
meeting will address how the GEWEX panels and their projects and working groups will continue
to work over the next 2 years to achieve their short-term goals, and how they will evolve toaccomplish post 2013 Imperatives. This process will include determining what enabling
infrastructure is necessary and developing a strategy for dealing with the GEWEX and WCRP
cross cutting or overarching themes.
According to the updated Pan-GEWEX agenda, each panel (including CEOP, GRP, andthth
GMPP) will have one and a half day (Tuesday 24 and Wednesday 25 morning) of separatethsessions dedicated to its own issues. A CEOP evening session on Thursday 26 August has
been added on the CEOP request. In addition, a half day for panel interaction is scheduled onthWednesday 25 afternoon. Further information including logistics details can be found at themeeting website.
Consequently, it has been noted that considering the outcomes the individual GEWEX
Panels including CEOP are expected to deliver at the Pan-GEWEX meeting, the available timemight not be sufficient to also address all the necessary CEOP internal planning issues to the full
extent. Accordingly, it has been decided that the Pan-GEWEX meeting CEOP sessions would notthfully substitute the 4 CEOP Annual Meeting event and that would be considered to take place
early in 2011.
3.2 Overall status of the CEOP reference site data archive and related issues(3.2a) Williams and Loehrer provided updated overall status of the Americas reference sitesthat is copied below in Attachment 1 and can also be accessed on the Internet at:
http://data.eol.ucar.edu/master_list/?project=CEOP/EOP-3/4.
(3.2b) Williams reiterated the ongoing action A2 on updating the site documentation/metadatathat all of the Reference site Managers and RHP Representatives were asked to undertake.

Namely, they should go on line to review all the documentation for their Reference sites that isavailable through the following web site: http://www.eol.ucar.edu/projects/ceop/dm/insitu/sites/
and to verify that it is complete and accurate and report necessary updates to Williams.
(3.2c) Williams also reiterated that the discussion in the CEOP model community and thedefinition of the scientific foci for the new CEOP period has resulted in the interest in / request for
additional data from the CEOP in-situ reference sites. This mainly covers three groups ofparameters: clouds, aerosol, and groundwater. It would be desirable if the Reference Site
Managers complete the survey and provide this information to the NCAR/EOL database. The online survey is located at: https://survey.ucar.edu/s?s=3003 and can be found through the DataManagement site at: http://www.eol.ucar.edu/projects/ceop/dm/questionnaires/.

RHP and Reference Site Reports

4.1 CPPA by Jin Huang, Tilden Meyers, and Steve Williams(4.1a) Huang advised the group that the NOAA's Climate Program Office was in the process ofrestructuring its grants programs (http://www.climate.noaa.gov/cpo_pa/). The grant activities are
now organized within four Programs, and the elements of CPPA are included in two of these,
namely the Modeling, Analysis, Predictions, and Projections (MAPP) Program and The Earth
System Science (ESS) Program. The CPPA observing activities are being funded through the
MAPP Program.
In this context, Huang mentioned that the NOAA CPO support currently provided to the
CEOP Data Management team at NCAR through the CPPA project would continue till the end of
2010. Since 2011, a new way through the MAPP Program will be sought.
(4.1b) Huang voiced that the 10-Year Dataset Project would be of high interest for the MAPP
Program and requested further details on this activity. It was mentioned that a Whitepaper on the
10-Year Dataset Project would be developed and submitted to the Pan-GEWEX meeting fordiscussion and revision.
(4.1c) Meyers reported in writing that they were are developing and testing a new gap filling
procedure in order to provide the best estimates of fluxes, including water and CO2, since these
are used to generated seasonal sums etc. for carbon and water budgets. They are using a
combination models that have been tuned to their data and have found this superior to standard
regression or statistical methods. The development and testing phase of this new procedure has
been completed and implementation will begin soon.
Certain problems have been found with the winter precipitation but correction has been
underway and almost completed. The team has also included both MODIS derived NDVI andtheir own in-situ NDVI that is tuned to get the seasonal trend in the LAI, which is very importantfor models. For 2010, three more variables will be added in the Bondville site dataset that include:(i) snow depth, (ii) fractional snow coverage, and (iii) in some cases, snow density. These aredetermined from the live internet PZT (Pan-zoom-tilt) camera installed at the site.
Regarding the data submission to the CEOP Data Archive (CDA) at NCAR, the team plan
is to provide a complete final product to all the requesting data repositories including the CDA,FLUXNET, and eventually NCDC at once and with supreme quality. Therefore the team isdedicating special efforts to the data quality control and gap filling procedures. Meyers indicatedthat part of the gapfilled and corrected observation datasets would be submitted to the CDA in
July.
(4.1d) Williams reported that the SGP sites data were almost complete up to 2009.
Nevertheless, he pointed out that there had been substantial changes in terms of individual
station locations (number of stations had been shut down and new would be installed in 2011) inorder to better fit to higher model resolutions. This needs to be considered when if the SGP site isnominated for contribution to the 10-YDP. It may require that a subset of stations is selected thathave been in operation at the same location since the beginning of the CEOP (or 10-YDP) period.
Williams also voiced that the ARM sites had also completed their data submission up to2009 and thus were good candidates for the 10-YDP.
4.2 LPB by Hugo Berbery(4.2a) Berbery reiterated that the LPB reference site Cruz Alta was working well and data werebeing collected. Debora Roberti, CPTEC, the Cruz Alta site representative for CEOP had sent
certain datasets to the CDA but several issues with the data were found and reported back toRoberti in April. The NCAR team is still anticipating a reply from her. It was proposed and agreed
that another note is sent to her from the NCAR team with a copy to Berbery, who would assist incommunication between Roberti and the NCAR team if necessary (action A3). The Cruz Alta site
documentation has not been submitted yet and is also requested.
(4.2b) Berbery further voiced that he and Dennis Lettenmaier attended the LPB meeting inArgentina in April 2010 visited two additional flux sites in the La Plata basin that have been in
operation since 1999 and planned to continue in observations and could possibly provide data to
CEOP.
Berbery also advised the group that an idea of a filed campaign in the basin had
emerged and been discussed among the US and Argentinean scientists, who were muchinterested in such activity. Berbery will inform the group of progress on this matter in due course.
(4.2c) Berbery also mentioned that the LPB community was very active, the most of theactivities
being
coordinatedbythe
CLARIS
LPB
Consortium(http://eolo.cima.fcen.uba.ar/~sweb/index.php), which is mainly funded by the European
Commission. The consortium involves about 20 Partners who contribute to international
Programmes or Projects, some have very strong links with stakeholders or governmental
decision-makers. Accordingly, the CLARIS LPB activities are carried out more independently,
similarly like in the AMMA RHP. It was noted at the call that while the work was being done on thebasin by the CLARIS group, it might be desirable for CEOP to focus on their reporting.
4.3 LBA by Luiz Horta, Alessandro Araujo(4.3a) Horta reported that the new person hired by on a full-time position for the LBA referencesite data processing had begun the work on the LBA data using a fully operational program andthus further data submissions from LBA might be expected in the near future.
He also voiced that a prototype system monitoring site sensors and transmitting data in
the real time that had been installed at the Manaus site would also be installed at the Santaremsite soon, which would expedite the data collection process.
Araujo reported that the 2006-2007 data from the Manaus and Santarem sites were
under preparation and would be submitted to NCAR soon.
(4.3b) Horta and Araujo mentioned that the possible candidates for the 10-YDP were Manaus
and Santarem sites. These sites have 11 years record of data, the longest-ever record in tropics.
Nevertheless, the LBA data policy restricts the data release, it is not allowed to provide the data
earlier than 1.5 year after observation/collection. Koike mentioned that the 10-YDP was in the
preparatory phase and the discussion on the data sharing/release would take place at higher
GEWEX management level after the Whitepaper has been presented, discussed, and revised
and the Pan-GEWEX meeting. Generally, the 1.5 year delay of the data release might not be anissue, depending on the exact 10-year period that is yet to be decided.

4.4 CliC BERMS sites by Alan Barr
Barr reported that the BERMS sites were working well and further datasets (beyond 2006) would
be processed and submitted to CEOP in the near future. He also mentioned that they would be
willing to contribute their data to the 10-year dataset.
ATTACHMENT 1:

CEOP AND CEOP DATA GROUP GENERAL ISSUES(3.1a) Benedict welcomed participants on the call and appreciated the work that the Americas
RHP and reference site teams had undertaken in response to the action items from the last call.

(3.1b) Koike reiterated that a 10-Year Dataset project had been initiated in response to theclimate modeling community need of a high quality observation data of a sufficient length forevaluation of climate models under the CMIP5 project and quantification of model projections
uncertainties. This activity was proposed by the WCRP Observation and Assimilation Panelrd(WOAP) and is compliant with the CEOP commitment taken at the 3 Annual CEOP Meeting in
Melbourne in August 2009 to develop the CEOP 10-year dataset as well as with the GEWEX
post 2013 Imperatives (http://www.gewex.org/2010pangewex/Draft_Imperatives.pdf). The
WOAP suggested activity, coordinated by CEOP (T. Koike) and CMIP5 (Karl Taylor), isenvisioned as a collaborative effort of a broader observation and climate modeling communities
including GEWEX/CEOP, LandFlux-EVAL, GSWP, AsiaFlux, from the observation side. The
targeted dataset will consists of in-situ as well as satellite observations from multiple providers
including CEOP, FLUXNET, AsiaFlux, iLEAPS.
Consequently, the 10-Year Dataset project was discussed with the LandFlux-EVAL,FLUXNET, AsiaFlux, and GSWP representatives at the occasion of the HESSS2 Meeting inTokyo in June and it was agreed that a Whitepaper would have been developed and submitted
for discussion at the Pan-GEWEX meeting in August.
In this context the representatives of the sites that had been in operation since CEOP
Phase 1 were asked for kind cooperation on this task. These include Meyers (CPPA-Bondville),
Williams (SGP, ARM sites), Barr/Thompson (BERMS sites), and Horta/Araujo (LBA sites).
(3.1c) It was also reiterated that in order to demonstrate benefits of the CEOP special dataarchives it would be desirable to undergo an external review process that would clearly show thevalue that is added to the collected data including reference site and satellite observations
through the CEOP data format unification and data integration efforts. This step is necessary forassuring an adequate incentive for funding agencies to continue to support the CEOP data
activities. It was agreed that such external review was very important and reactivation of aninternational science and advisory group should be considered.
nd(3.1d) Benedict reiterated that the 2 Pan-GEWEX meeting would take place in Seattle, USA,
23 – 27 August 2010 (http://www.gewex.org/2010pangewex/home.html). The Pan-GEWEX
meeting will address how the GEWEX panels and their projects and working groups will continue
to work over the next 2 years to achieve their short-term goals, and how they will evolve toaccomplish post 2013 Imperatives. This process will include determining what enabling
infrastructure is necessary and developing a strategy for dealing with the GEWEX and WCRP
cross cutting or overarching themes.
According to the updated Pan-GEWEX agenda, each panel (including CEOP, GRP, andthth
GMPP) will have one and a half day (Tuesday 24 and Wednesday 25 morning) of separatethsessions dedicated to its own issues. A CEOP evening session on Thursday 26 August has
been added on the CEOP request. In addition, a half day for panel interaction is scheduled onthWednesday 25 afternoon. Further information including logistics details can be found at themeeting website.
Consequently, it has been noted that considering the outcomes the individual GEWEX
Panels including CEOP are expected to deliver at the Pan-GEWEX meeting, the available timemight not be sufficient to also address all the necessary CEOP internal planning issues to the full
extent. Accordingly, it has been decided that the Pan-GEWEX meeting CEOP sessions would notthfully substitute the 4 CEOP Annual Meeting event and that would be considered to take place
early in 2011.
3.2 Overall status of the CEOP reference site data archive and related issues(3.2a) Williams and Loehrer provided updated overall status of the Americas reference sitesthat is copied below in Attachment 1 and can also be accessed on the Internet at:
http://data.eol.ucar.edu/master_list/?project=CEOP/EOP-3/4.
(3.2b) Williams reiterated the ongoing action A2 on updating the site documentation/metadatathat all of the Reference site Managers and RHP Representatives were asked to undertake.

Namely, they should go on line to review all the documentation for their Reference sites that isavailable through the following web site: http://www.eol.ucar.edu/projects/ceop/dm/insitu/sites/
and to verify that it is complete and accurate and report necessary updates to Williams.
(3.2c) Williams also reiterated that the discussion in the CEOP model community and thedefinition of the scientific foci for the new CEOP period has resulted in the interest in / request for
additional data from the CEOP in-situ reference sites. This mainly covers three groups ofparameters: clouds, aerosol, and groundwater. It would be desirable if the Reference Site
Managers complete the survey and provide this information to the NCAR/EOL database. The online survey is located at: https://survey.ucar.edu/s?s=3003 and can be found through the DataManagement site at: http://www.eol.ucar.edu/projects/ceop/dm/questionnaires/.

RHP and Reference Site Reports

4.1 CPPA by Jin Huang, Tilden Meyers, and Steve Williams(4.1a) Huang advised the group that the NOAA's Climate Program Office was in the process ofrestructuring its grants programs (http://www.climate.noaa.gov/cpo_pa/). The grant activities are
now organized within four Programs, and the elements of CPPA are included in two of these,
namely the Modeling, Analysis, Predictions, and Projections (MAPP) Program and The Earth
System Science (ESS) Program. The CPPA observing activities are being funded through the
MAPP Program.
In this context, Huang mentioned that the NOAA CPO support currently provided to the
CEOP Data Management team at NCAR through the CPPA project would continue till the end of
2010. Since 2011, a new way through the MAPP Program will be sought.
(4.1b) Huang voiced that the 10-Year Dataset Project would be of high interest for the MAPP
Program and requested further details on this activity. It was mentioned that a Whitepaper on the
10-Year Dataset Project would be developed and submitted to the Pan-GEWEX meeting fordiscussion and revision.
(4.1c) Meyers reported in writing that they were are developing and testing a new gap filling
procedure in order to provide the best estimates of fluxes, including water and CO2, since these
are used to generated seasonal sums etc. for carbon and water budgets. They are using a
combination models that have been tuned to their data and have found this superior to standard
regression or statistical methods. The development and testing phase of this new procedure has
been completed and implementation will begin soon.
Certain problems have been found with the winter precipitation but correction has been
underway and almost completed. The team has also included both MODIS derived NDVI andtheir own in-situ NDVI that is tuned to get the seasonal trend in the LAI, which is very importantfor models. For 2010, three more variables will be added in the Bondville site dataset that include:(i) snow depth, (ii) fractional snow coverage, and (iii) in some cases, snow density. These aredetermined from the live internet PZT (Pan-zoom-tilt) camera installed at the site.
Regarding the data submission to the CEOP Data Archive (CDA) at NCAR, the team plan
is to provide a complete final product to all the requesting data repositories including the CDA,FLUXNET, and eventually NCDC at once and with supreme quality. Therefore the team isdedicating special efforts to the data quality control and gap filling procedures. Meyers indicatedthat part of the gapfilled and corrected observation datasets would be submitted to the CDA in
July.
(4.1d) Williams reported that the SGP sites data were almost complete up to 2009.
Nevertheless, he pointed out that there had been substantial changes in terms of individual
station locations (number of stations had been shut down and new would be installed in 2011) inorder to better fit to higher model resolutions. This needs to be considered when if the SGP site isnominated for contribution to the 10-YDP. It may require that a subset of stations is selected thathave been in operation at the same location since the beginning of the CEOP (or 10-YDP) period.
Williams also voiced that the ARM sites had also completed their data submission up to2009 and thus were good candidates for the 10-YDP.
4.2 LPB by Hugo Berbery(4.2a) Berbery reiterated that the LPB reference site Cruz Alta was working well and data werebeing collected. Debora Roberti, CPTEC, the Cruz Alta site representative for CEOP had sent
certain datasets to the CDA but several issues with the data were found and reported back toRoberti in April. The NCAR team is still anticipating a reply from her. It was proposed and agreed
that another note is sent to her from the NCAR team with a copy to Berbery, who would assist incommunication between Roberti and the NCAR team if necessary (action A3). The Cruz Alta site
documentation has not been submitted yet and is also requested.
(4.2b) Berbery further voiced that he and Dennis Lettenmaier attended the LPB meeting inArgentina in April 2010 visited two additional flux sites in the La Plata basin that have been in
operation since 1999 and planned to continue in observations and could possibly provide data to
CEOP.
Berbery also advised the group that an idea of a filed campaign in the basin had
emerged and been discussed among the US and Argentinean scientists, who were muchinterested in such activity. Berbery will inform the group of progress on this matter in due course.
(4.2c) Berbery also mentioned that the LPB community was very active, the most of theactivities
being
coordinatedbythe
CLARIS
LPB
Consortium(http://eolo.cima.fcen.uba.ar/~sweb/index.php), which is mainly funded by the European
Commission. The consortium involves about 20 Partners who contribute to international
Programmes or Projects, some have very strong links with stakeholders or governmental
decision-makers. Accordingly, the CLARIS LPB activities are carried out more independently,
similarly like in the AMMA RHP. It was noted at the call that while the work was being done on thebasin by the CLARIS group, it might be desirable for CEOP to focus on their reporting.
4.3 LBA by Luiz Horta, Alessandro Araujo(4.3a) Horta reported that the new person hired by on a full-time position for the LBA referencesite data processing had begun the work on the LBA data using a fully operational program andthus further data submissions from LBA might be expected in the near future.
He also voiced that a prototype system monitoring site sensors and transmitting data in
the real time that had been installed at the Manaus site would also be installed at the Santaremsite soon, which would expedite the data collection process.
Araujo reported that the 2006-2007 data from the Manaus and Santarem sites were
under preparation and would be submitted to NCAR soon.
(4.3b) Horta and Araujo mentioned that the possible candidates for the 10-YDP were Manaus
and Santarem sites. These sites have 11 years record of data, the longest-ever record in tropics.
Nevertheless, the LBA data policy restricts the data release, it is not allowed to provide the data
earlier than 1.5 year after observation/collection. Koike mentioned that the 10-YDP was in the
preparatory phase and the discussion on the data sharing/release would take place at higher
GEWEX management level after the Whitepaper has been presented, discussed, and revised
and the Pan-GEWEX meeting. Generally, the 1.5 year delay of the data release might not be anissue, depending on the exact 10-year period that is yet to be decided.

4.4 CliC BERMS sites by Alan Barr
Barr reported that the BERMS sites were working well and further datasets (beyond 2006) would
be processed and submitted to CEOP in the near future. He also mentioned that they would be
willing to contribute their data to the 10-year dataset.
ATTACHMENT 1:

Phase 1 were asked for kind cooperation on this task. These include Meyers (CPPA-Bondville),
Williams (SGP, ARM sites), Barr/Thompson (BERMS sites), and Horta/Araujo (LBA sites).
(3.1c) It was also reiterated that in order to demonstrate benefits of the CEOP special dataarchives it would be desirable to undergo an external review process that would clearly show thevalue that is added to the collected data including reference site and satellite observations
through the CEOP data format unification and data integration efforts. This step is necessary forassuring an adequate incentive for funding agencies to continue to support the CEOP data
activities. It was agreed that such external review was very important and reactivation of aninternational science and advisory group should be considered.
nd(3.1d) Benedict reiterated that the 2 Pan-GEWEX meeting would take place in Seattle, USA,
23 – 27 August 2010 (http://www.gewex.org/2010pangewex/home.html). The Pan-GEWEX
meeting will address how the GEWEX panels and their projects and working groups will continue
to work over the next 2 years to achieve their short-term goals, and how they will evolve toaccomplish post 2013 Imperatives. This process will include determining what enabling
infrastructure is necessary and developing a strategy for dealing with the GEWEX and WCRP
cross cutting or overarching themes.
According to the updated Pan-GEWEX agenda, each panel (including CEOP, GRP, andthth
GMPP) will have one and a half day (Tuesday 24 and Wednesday 25 morning) of separatethsessions dedicated to its own issues. A CEOP evening session on Thursday 26 August has
been added on the CEOP request. In addition, a half day for panel interaction is scheduled onthWednesday 25 afternoon. Further information including logistics details can be found at themeeting website.
Consequently, it has been noted that considering the outcomes the individual GEWEX
Panels including CEOP are expected to deliver at the Pan-GEWEX meeting, the available timemight not be sufficient to also address all the necessary CEOP internal planning issues to the full
extent. Accordingly, it has been decided that the Pan-GEWEX meeting CEOP sessions would notthfully substitute the 4 CEOP Annual Meeting event and that would be considered to take place
early in 2011.
3.2 Overall status of the CEOP reference site data archive and related issues(3.2a) Williams and Loehrer provided updated overall status of the Americas reference sitesthat is copied below in Attachment 1 and can also be accessed on the Internet at:
http://data.eol.ucar.edu/master_list/?project=CEOP/EOP-3/4.
(3.2b) Williams reiterated the ongoing action A2 on updating the site documentation/metadatathat all of the Reference site Managers and RHP Representatives were asked to undertake.

Namely, they should go on line to review all the documentation for their Reference sites that isavailable through the following web site: http://www.eol.ucar.edu/projects/ceop/dm/insitu/sites/
and to verify that it is complete and accurate and report necessary updates to Williams.
(3.2c) Williams also reiterated that the discussion in the CEOP model community and thedefinition of the scientific foci for the new CEOP period has resulted in the interest in / request for
additional data from the CEOP in-situ reference sites. This mainly covers three groups ofparameters: clouds, aerosol, and groundwater. It would be desirable if the Reference Site
Managers complete the survey and provide this information to the NCAR/EOL database. The online survey is located at: https://survey.ucar.edu/s?s=3003 and can be found through the DataManagement site at: http://www.eol.ucar.edu/projects/ceop/dm/questionnaires/.

RHP and Reference Site Reports

4.1 CPPA by Jin Huang, Tilden Meyers, and Steve Williams(4.1a) Huang advised the group that the NOAA's Climate Program Office was in the process ofrestructuring its grants programs (http://www.climate.noaa.gov/cpo_pa/). The grant activities are
now organized within four Programs, and the elements of CPPA are included in two of these,
namely the Modeling, Analysis, Predictions, and Projections (MAPP) Program and The Earth
System Science (ESS) Program. The CPPA observing activities are being funded through the
MAPP Program.
In this context, Huang mentioned that the NOAA CPO support currently provided to the
CEOP Data Management team at NCAR through the CPPA project would continue till the end of
2010. Since 2011, a new way through the MAPP Program will be sought.
(4.1b) Huang voiced that the 10-Year Dataset Project would be of high interest for the MAPP
Program and requested further details on this activity. It was mentioned that a Whitepaper on the
10-Year Dataset Project would be developed and submitted to the Pan-GEWEX meeting fordiscussion and revision.
(4.1c) Meyers reported in writing that they were are developing and testing a new gap filling
procedure in order to provide the best estimates of fluxes, including water and CO2, since these
are used to generated seasonal sums etc. for carbon and water budgets. They are using a
combination models that have been tuned to their data and have found this superior to standard
regression or statistical methods. The development and testing phase of this new procedure has
been completed and implementation will begin soon.
Certain problems have been found with the winter precipitation but correction has been
underway and almost completed. The team has also included both MODIS derived NDVI andtheir own in-situ NDVI that is tuned to get the seasonal trend in the LAI, which is very importantfor models. For 2010, three more variables will be added in the Bondville site dataset that include:(i) snow depth, (ii) fractional snow coverage, and (iii) in some cases, snow density. These aredetermined from the live internet PZT (Pan-zoom-tilt) camera installed at the site.
Regarding the data submission to the CEOP Data Archive (CDA) at NCAR, the team plan
is to provide a complete final product to all the requesting data repositories including the CDA,FLUXNET, and eventually NCDC at once and with supreme quality. Therefore the team isdedicating special efforts to the data quality control and gap filling procedures. Meyers indicatedthat part of the gapfilled and corrected observation datasets would be submitted to the CDA in
July.
(4.1d) Williams reported that the SGP sites data were almost complete up to 2009.
Nevertheless, he pointed out that there had been substantial changes in terms of individual
station locations (number of stations had been shut down and new would be installed in 2011) inorder to better fit to higher model resolutions. This needs to be considered when if the SGP site isnominated for contribution to the 10-YDP. It may require that a subset of stations is selected thathave been in operation at the same location since the beginning of the CEOP (or 10-YDP) period.
Williams also voiced that the ARM sites had also completed their data submission up to2009 and thus were good candidates for the 10-YDP.
4.2 LPB by Hugo Berbery(4.2a) Berbery reiterated that the LPB reference site Cruz Alta was working well and data werebeing collected. Debora Roberti, CPTEC, the Cruz Alta site representative for CEOP had sent
certain datasets to the CDA but several issues with the data were found and reported back toRoberti in April. The NCAR team is still anticipating a reply from her. It was proposed and agreed
that another note is sent to her from the NCAR team with a copy to Berbery, who would assist incommunication between Roberti and the NCAR team if necessary (action A3). The Cruz Alta site
documentation has not been submitted yet and is also requested.
(4.2b) Berbery further voiced that he and Dennis Lettenmaier attended the LPB meeting inArgentina in April 2010 visited two additional flux sites in the La Plata basin that have been in
operation since 1999 and planned to continue in observations and could possibly provide data to
CEOP.
Berbery also advised the group that an idea of a filed campaign in the basin had
emerged and been discussed among the US and Argentinean scientists, who were muchinterested in such activity. Berbery will inform the group of progress on this matter in due course.
(4.2c) Berbery also mentioned that the LPB community was very active, the most of theactivities
being
coordinatedbythe
CLARIS
LPB
Consortium(http://eolo.cima.fcen.uba.ar/~sweb/index.php), which is mainly funded by the European
Commission. The consortium involves about 20 Partners who contribute to international
Programmes or Projects, some have very strong links with stakeholders or governmental
decision-makers. Accordingly, the CLARIS LPB activities are carried out more independently,
similarly like in the AMMA RHP. It was noted at the call that while the work was being done on thebasin by the CLARIS group, it might be desirable for CEOP to focus on their reporting.
4.3 LBA by Luiz Horta, Alessandro Araujo(4.3a) Horta reported that the new person hired by on a full-time position for the LBA referencesite data processing had begun the work on the LBA data using a fully operational program andthus further data submissions from LBA might be expected in the near future.
He also voiced that a prototype system monitoring site sensors and transmitting data in
the real time that had been installed at the Manaus site would also be installed at the Santaremsite soon, which would expedite the data collection process.
Araujo reported that the 2006-2007 data from the Manaus and Santarem sites were
under preparation and would be submitted to NCAR soon.
(4.3b) Horta and Araujo mentioned that the possible candidates for the 10-YDP were Manaus
and Santarem sites. These sites have 11 years record of data, the longest-ever record in tropics.
Nevertheless, the LBA data policy restricts the data release, it is not allowed to provide the data
earlier than 1.5 year after observation/collection. Koike mentioned that the 10-YDP was in the
preparatory phase and the discussion on the data sharing/release would take place at higher
GEWEX management level after the Whitepaper has been presented, discussed, and revised
and the Pan-GEWEX meeting. Generally, the 1.5 year delay of the data release might not be anissue, depending on the exact 10-year period that is yet to be decided.

4.4 CliC BERMS sites by Alan Barr
Barr reported that the BERMS sites were working well and further datasets (beyond 2006) would
be processed and submitted to CEOP in the near future. He also mentioned that they would be
willing to contribute their data to the 10-year dataset.
ATTACHMENT 1:

CEOP AND CEOP DATA GROUP GENERAL ISSUES(3.1a) Benedict welcomed participants on the call and appreciated the work that the Americas
RHP and reference site teams had undertaken in response to the action items from the last call.

(3.1b) Koike reiterated that a 10-Year Dataset project had been initiated in response to theclimate modeling community need of a high quality observation data of a sufficient length forevaluation of climate models under the CMIP5 project and quantification of model projections
uncertainties. This activity was proposed by the WCRP Observation and Assimilation Panelrd(WOAP) and is compliant with the CEOP commitment taken at the 3 Annual CEOP Meeting in
Melbourne in August 2009 to develop the CEOP 10-year dataset as well as with the GEWEX
post 2013 Imperatives (http://www.gewex.org/2010pangewex/Draft_Imperatives.pdf). The
WOAP suggested activity, coordinated by CEOP (T. Koike) and CMIP5 (Karl Taylor), isenvisioned as a collaborative effort of a broader observation and climate modeling communities
including GEWEX/CEOP, LandFlux-EVAL, GSWP, AsiaFlux, from the observation side. The
targeted dataset will consists of in-situ as well as satellite observations from multiple providers
including CEOP, FLUXNET, AsiaFlux, iLEAPS.
Consequently, the 10-Year Dataset project was discussed with the LandFlux-EVAL,FLUXNET, AsiaFlux, and GSWP representatives at the occasion of the HESSS2 Meeting inTokyo in June and it was agreed that a Whitepaper would have been developed and submitted
for discussion at the Pan-GEWEX meeting in August.

extent. Accordingly, it has been decided that the Pan-GEWEX meeting CEOP sessions would notthfully substitute the 4 CEOP Annual Meeting event and that would be considered to take place
early in 2011.
3.2 Overall status of the CEOP reference site data archive and related issues(3.2a) Williams and Loehrer provided updated overall status of the Americas reference sitesthat is copied below in Attachment 1 and can also be accessed on the Internet at:
http://data.eol.ucar.edu/master_list/?project=CEOP/EOP-3/4.
(3.2b) Williams reiterated the ongoing action A2 on updating the site documentation/metadatathat all of the Reference site Managers and RHP Representatives were asked to undertake.

Namely, they should go on line to review all the documentation for their Reference sites that isavailable through the following web site: http://www.eol.ucar.edu/projects/ceop/dm/insitu/sites/
and to verify that it is complete and accurate and report necessary updates to Williams.
(3.2c) Williams also reiterated that the discussion in the CEOP model community and thedefinition of the scientific foci for the new CEOP period has resulted in the interest in / request for
additional data from the CEOP in-situ reference sites. This mainly covers three groups ofparameters: clouds, aerosol, and groundwater. It would be desirable if the Reference Site
Managers complete the survey and provide this information to the NCAR/EOL database. The online survey is located at: https://survey.ucar.edu/s?s=3003 and can be found through the DataManagement site at: http://www.eol.ucar.edu/projects/ceop/dm/questionnaires/.

RHP and Reference Site Reports

4.1 CPPA by Jin Huang, Tilden Meyers, and Steve Williams(4.1a) Huang advised the group that the NOAA's Climate Program Office was in the process ofrestructuring its grants programs (http://www.climate.noaa.gov/cpo_pa/). The grant activities are
now organized within four Programs, and the elements of CPPA are included in two of these,
namely the Modeling, Analysis, Predictions, and Projections (MAPP) Program and The Earth
System Science (ESS) Program. The CPPA observing activities are being funded through the
MAPP Program.
In this context, Huang mentioned that the NOAA CPO support currently provided to the
CEOP Data Management team at NCAR through the CPPA project would continue till the end of
2010. Since 2011, a new way through the MAPP Program will be sought.
(4.1b) Huang voiced that the 10-Year Dataset Project would be of high interest for the MAPP
Program and requested further details on this activity. It was mentioned that a Whitepaper on the
10-Year Dataset Project would be developed and submitted to the Pan-GEWEX meeting fordiscussion and revision.
(4.1c) Meyers reported in writing that they were are developing and testing a new gap filling
procedure in order to provide the best estimates of fluxes, including water and CO2, since these
are used to generated seasonal sums etc. for carbon and water budgets. They are using a
combination models that have been tuned to their data and have found this superior to standard
regression or statistical methods. The development and testing phase of this new procedure has
been completed and implementation will begin soon.
Certain problems have been found with the winter precipitation but correction has been
underway and almost completed. The team has also included both MODIS derived NDVI andtheir own in-situ NDVI that is tuned to get the seasonal trend in the LAI, which is very importantfor models. For 2010, three more variables will be added in the Bondville site dataset that include:(i) snow depth, (ii) fractional snow coverage, and (iii) in some cases, snow density. These aredetermined from the live internet PZT (Pan-zoom-tilt) camera installed at the site.
Regarding the data submission to the CEOP Data Archive (CDA) at NCAR, the team plan
is to provide a complete final product to all the requesting data repositories including the CDA,FLUXNET, and eventually NCDC at once and with supreme quality. Therefore the team isdedicating special efforts to the data quality control and gap filling procedures. Meyers indicatedthat part of the gapfilled and corrected observation datasets would be submitted to the CDA in
July.
(4.1d) Williams reported that the SGP sites data were almost complete up to 2009.
Nevertheless, he pointed out that there had been substantial changes in terms of individual
station locations (number of stations had been shut down and new would be installed in 2011) inorder to better fit to higher model resolutions. This needs to be considered when if the SGP site isnominated for contribution to the 10-YDP. It may require that a subset of stations is selected thathave been in operation at the same location since the beginning of the CEOP (or 10-YDP) period.
Williams also voiced that the ARM sites had also completed their data submission up to2009 and thus were good candidates for the 10-YDP.
4.2 LPB by Hugo Berbery(4.2a) Berbery reiterated that the LPB reference site Cruz Alta was working well and data werebeing collected. Debora Roberti, CPTEC, the Cruz Alta site representative for CEOP had sent
certain datasets to the CDA but several issues with the data were found and reported back toRoberti in April. The NCAR team is still anticipating a reply from her. It was proposed and agreed
that another note is sent to her from the NCAR team with a copy to Berbery, who would assist incommunication between Roberti and the NCAR team if necessary (action A3). The Cruz Alta site
documentation has not been submitted yet and is also requested.
(4.2b) Berbery further voiced that he and Dennis Lettenmaier attended the LPB meeting inArgentina in April 2010 visited two additional flux sites in the La Plata basin that have been in
operation since 1999 and planned to continue in observations and could possibly provide data to
CEOP.
Berbery also advised the group that an idea of a filed campaign in the basin had
emerged and been discussed among the US and Argentinean scientists, who were muchinterested in such activity. Berbery will inform the group of progress on this matter in due course.
(4.2c) Berbery also mentioned that the LPB community was very active, the most of theactivities
being
coordinatedbythe
CLARIS
LPB
Consortium(http://eolo.cima.fcen.uba.ar/~sweb/index.php), which is mainly funded by the European
Commission. The consortium involves about 20 Partners who contribute to international
Programmes or Projects, some have very strong links with stakeholders or governmental
decision-makers. Accordingly, the CLARIS LPB activities are carried out more independently,
similarly like in the AMMA RHP. It was noted at the call that while the work was being done on thebasin by the CLARIS group, it might be desirable for CEOP to focus on their reporting.
4.3 LBA by Luiz Horta, Alessandro Araujo(4.3a) Horta reported that the new person hired by on a full-time position for the LBA referencesite data processing had begun the work on the LBA data using a fully operational program andthus further data submissions from LBA might be expected in the near future.
He also voiced that a prototype system monitoring site sensors and transmitting data in
the real time that had been installed at the Manaus site would also be installed at the Santaremsite soon, which would expedite the data collection process.
Araujo reported that the 2006-2007 data from the Manaus and Santarem sites were
under preparation and would be submitted to NCAR soon.
(4.3b) Horta and Araujo mentioned that the possible candidates for the 10-YDP were Manaus
and Santarem sites. These sites have 11 years record of data, the longest-ever record in tropics.
Nevertheless, the LBA data policy restricts the data release, it is not allowed to provide the data
earlier than 1.5 year after observation/collection. Koike mentioned that the 10-YDP was in the
preparatory phase and the discussion on the data sharing/release would take place at higher
GEWEX management level after the Whitepaper has been presented, discussed, and revised
and the Pan-GEWEX meeting. Generally, the 1.5 year delay of the data release might not be anissue, depending on the exact 10-year period that is yet to be decided.

4.4 CliC BERMS sites by Alan Barr
Barr reported that the BERMS sites were working well and further datasets (beyond 2006) would
be processed and submitted to CEOP in the near future. He also mentioned that they would be
willing to contribute their data to the 10-year dataset.

NEXT CONFERENCE CALLth

The next, 7 CEOP Americas RHP and Reference Sites Teleconference is proposed to takeplace on Tuesday 12 October 2010 at 20:00 UTC. Benedict and Koudelova have the action(A1) to inform the group of the details of the next call nearer to the time of the call and tocoordinate the origination of the call (action A1a). In this context, a calendar of the dates andtimes of all the CEOP conference calls for 2010-2011 was distributed to the participants for their
future reference that is also available through the CEOP homepage at: http://monsoon.t.utokyo.ac.jp/ceop2/calls.html.

CEOP AND CEOP DATA GROUP GENERAL ISSUES(3.1a) Benedict welcomed participants on the call and appreciated the work that the Americas
RHP and reference site teams had undertaken in response to the action items from the last call.

(3.1b) Koike reiterated that a 10-Year Dataset project had been initiated in response to theclimate modeling community need of a high quality observation data of a sufficient length forevaluation of climate models under the CMIP5 project and quantification of model projections
uncertainties. This activity was proposed by the WCRP Observation and Assimilation Panelrd(WOAP) and is compliant with the CEOP commitment taken at the 3 Annual CEOP Meeting in
Melbourne in August 2009 to develop the CEOP 10-year dataset as well as with the GEWEX
post 2013 Imperatives (http://www.gewex.org/2010pangewex/Draft_Imperatives.pdf). The
WOAP suggested activity, coordinated by CEOP (T. Koike) and CMIP5 (Karl Taylor), isenvisioned as a collaborative effort of a broader observation and climate modeling communities
including GEWEX/CEOP, LandFlux-EVAL, GSWP, AsiaFlux, from the observation side. The
targeted dataset will consists of in-situ as well as satellite observations from multiple providers
including CEOP, FLUXNET, AsiaFlux, iLEAPS.
Consequently, the 10-Year Dataset project was discussed with the LandFlux-EVAL,FLUXNET, AsiaFlux, and GSWP representatives at the occasion of the HESSS2 Meeting inTokyo in June and it was agreed that a Whitepaper would have been developed and submitted
for discussion at the Pan-GEWEX meeting in August.
In this context the representatives of the sites that had been in operation since CEOP
Phase 1 were asked for kind cooperation on this task. These include Meyers (CPPA-Bondville),
Williams (SGP, ARM sites), Barr/Thompson (BERMS sites), and Horta/Araujo (LBA sites).
(3.1c) It was also reiterated that in order to demonstrate benefits of the CEOP special dataarchives it would be desirable to undergo an external review process that would clearly show thevalue that is added to the collected data including reference site and satellite observations
through the CEOP data format unification and data integration efforts. This step is necessary forassuring an adequate incentive for funding agencies to continue to support the CEOP data
activities. It was agreed that such external review was very important and reactivation of aninternational science and advisory group should be considered.
nd(3.1d) Benedict reiterated that the 2 Pan-GEWEX meeting would take place in Seattle, USA,
23 – 27 August 2010 (http://www.gewex.org/2010pangewex/home.html). The Pan-GEWEX
meeting will address how the GEWEX panels and their projects and working groups will continue
to work over the next 2 years to achieve their short-term goals, and how they will evolve toaccomplish post 2013 Imperatives. This process will include determining what enabling
infrastructure is necessary and developing a strategy for dealing with the GEWEX and WCRP
cross cutting or overarching themes.
According to the updated Pan-GEWEX agenda, each panel (including CEOP, GRP, andthth
GMPP) will have one and a half day (Tuesday 24 and Wednesday 25 morning) of separatethsessions dedicated to its own issues. A CEOP evening session on Thursday 26 August has
been added on the CEOP request. In addition, a half day for panel interaction is scheduled onthWednesday 25 afternoon. Further information including logistics details can be found at themeeting website.
Consequently, it has been noted that considering the outcomes the individual GEWEX
Panels including CEOP are expected to deliver at the Pan-GEWEX meeting, the available timemight not be sufficient to also address all the necessary CEOP internal planning issues to the full
extent. Accordingly, it has been decided that the Pan-GEWEX meeting CEOP sessions would notthfully substitute the 4 CEOP Annual Meeting event and that would be considered to take place
early in 2011.
3.2 Overall status of the CEOP reference site data archive and related issues(3.2a) Williams and Loehrer provided updated overall status of the Americas reference sitesthat is copied below in Attachment 1 and can also be accessed on the Internet at:
http://data.eol.ucar.edu/master_list/?project=CEOP/EOP-3/4.
(3.2b) Williams reiterated the ongoing action A2 on updating the site documentation/metadatathat all of the Reference site Managers and RHP Representatives were asked to undertake.

Namely, they should go on line to review all the documentation for their Reference sites that isavailable through the following web site: http://www.eol.ucar.edu/projects/ceop/dm/insitu/sites/
and to verify that it is complete and accurate and report necessary updates to Williams.

namely the Modeling, Analysis, Predictions, and Projections (MAPP) Program and The Earth
System Science (ESS) Program. The CPPA observing activities are being funded through the
MAPP Program.
In this context, Huang mentioned that the NOAA CPO support currently provided to the
CEOP Data Management team at NCAR through the CPPA project would continue till the end of
2010. Since 2011, a new way through the MAPP Program will be sought.
(4.1b) Huang voiced that the 10-Year Dataset Project would be of high interest for the MAPP
Program and requested further details on this activity. It was mentioned that a Whitepaper on the
10-Year Dataset Project would be developed and submitted to the Pan-GEWEX meeting fordiscussion and revision.
(4.1c) Meyers reported in writing that they were are developing and testing a new gap filling
procedure in order to provide the best estimates of fluxes, including water and CO2, since these
are used to generated seasonal sums etc. for carbon and water budgets. They are using a
combination models that have been tuned to their data and have found this superior to standard
regression or statistical methods. The development and testing phase of this new procedure has
been completed and implementation will begin soon.
Certain problems have been found with the winter precipitation but correction has been
underway and almost completed. The team has also included both MODIS derived NDVI andtheir own in-situ NDVI that is tuned to get the seasonal trend in the LAI, which is very importantfor models. For 2010, three more variables will be added in the Bondville site dataset that include:(i) snow depth, (ii) fractional snow coverage, and (iii) in some cases, snow density. These aredetermined from the live internet PZT (Pan-zoom-tilt) camera installed at the site.
Regarding the data submission to the CEOP Data Archive (CDA) at NCAR, the team plan
is to provide a complete final product to all the requesting data repositories including the CDA,FLUXNET, and eventually NCDC at once and with supreme quality. Therefore the team isdedicating special efforts to the data quality control and gap filling procedures. Meyers indicatedthat part of the gapfilled and corrected observation datasets would be submitted to the CDA in
July.
(4.1d) Williams reported that the SGP sites data were almost complete up to 2009.
Nevertheless, he pointed out that there had been substantial changes in terms of individual
station locations (number of stations had been shut down and new would be installed in 2011) inorder to better fit to higher model resolutions. This needs to be considered when if the SGP site isnominated for contribution to the 10-YDP. It may require that a subset of stations is selected thathave been in operation at the same location since the beginning of the CEOP (or 10-YDP) period.
Williams also voiced that the ARM sites had also completed their data submission up to2009 and thus were good candidates for the 10-YDP.
4.2 LPB by Hugo Berbery(4.2a) Berbery reiterated that the LPB reference site Cruz Alta was working well and data werebeing collected. Debora Roberti, CPTEC, the Cruz Alta site representative for CEOP had sent
certain datasets to the CDA but several issues with the data were found and reported back toRoberti in April. The NCAR team is still anticipating a reply from her. It was proposed and agreed
that another note is sent to her from the NCAR team with a copy to Berbery, who would assist incommunication between Roberti and the NCAR team if necessary (action A3). The Cruz Alta site
documentation has not been submitted yet and is also requested.
(4.2b) Berbery further voiced that he and Dennis Lettenmaier attended the LPB meeting inArgentina in April 2010 visited two additional flux sites in the La Plata basin that have been in
operation since 1999 and planned to continue in observations and could possibly provide data to
CEOP.
Berbery also advised the group that an idea of a filed campaign in the basin had
emerged and been discussed among the US and Argentinean scientists, who were muchinterested in such activity. Berbery will inform the group of progress on this matter in due course.
(4.2c) Berbery also mentioned that the LPB community was very active, the most of theactivities
being
coordinatedbythe
CLARIS
LPB
Consortium(http://eolo.cima.fcen.uba.ar/~sweb/index.php), which is mainly funded by the European
Commission. The consortium involves about 20 Partners who contribute to international
Programmes or Projects, some have very strong links with stakeholders or governmental
decision-makers. Accordingly, the CLARIS LPB activities are carried out more independently,
similarly like in the AMMA RHP. It was noted at the call that while the work was being done on thebasin by the CLARIS group, it might be desirable for CEOP to focus on their reporting.
4.3 LBA by Luiz Horta, Alessandro Araujo(4.3a) Horta reported that the new person hired by on a full-time position for the LBA referencesite data processing had begun the work on the LBA data using a fully operational program andthus further data submissions from LBA might be expected in the near future.
He also voiced that a prototype system monitoring site sensors and transmitting data in
the real time that had been installed at the Manaus site would also be installed at the Santaremsite soon, which would expedite the data collection process.
Araujo reported that the 2006-2007 data from the Manaus and Santarem sites were
under preparation and would be submitted to NCAR soon.
(4.3b) Horta and Araujo mentioned that the possible candidates for the 10-YDP were Manaus
and Santarem sites. These sites have 11 years record of data, the longest-ever record in tropics.
Nevertheless, the LBA data policy restricts the data release, it is not allowed to provide the data
earlier than 1.5 year after observation/collection. Koike mentioned that the 10-YDP was in the
preparatory phase and the discussion on the data sharing/release would take place at higher
GEWEX management level after the Whitepaper has been presented, discussed, and revised
and the Pan-GEWEX meeting. Generally, the 1.5 year delay of the data release might not be anissue, depending on the exact 10-year period that is yet to be decided.

4.4 CliC BERMS sites by Alan Barr
Barr reported that the BERMS sites were working well and further datasets (beyond 2006) would
be processed and submitted to CEOP in the near future. He also mentioned that they would be
willing to contribute their data to the 10-year dataset.

NEXT CONFERENCE CALLth

The next, 7 CEOP Americas RHP and Reference Sites Teleconference is proposed to takeplace on Tuesday 12 October 2010 at 20:00 UTC. Benedict and Koudelova have the action(A1) to inform the group of the details of the next call nearer to the time of the call and tocoordinate the origination of the call (action A1a). In this context, a calendar of the dates andtimes of all the CEOP conference calls for 2010-2011 was distributed to the participants for their
future reference that is also available through the CEOP homepage at: http://monsoon.t.utokyo.ac.jp/ceop2/calls.html.

CEOP AND CEOP DATA GROUP GENERAL ISSUES(3.1a) Benedict welcomed participants on the call and appreciated the work that the Americas
RHP and reference site teams had undertaken in response to the action items from the last call.

(3.1b) Koike reiterated that a 10-Year Dataset project had been initiated in response to theclimate modeling community need of a high quality observation data of a sufficient length forevaluation of climate models under the CMIP5 project and quantification of model projections
uncertainties. This activity was proposed by the WCRP Observation and Assimilation Panelrd(WOAP) and is compliant with the CEOP commitment taken at the 3 Annual CEOP Meeting in
Melbourne in August 2009 to develop the CEOP 10-year dataset as well as with the GEWEX
post 2013 Imperatives (http://www.gewex.org/2010pangewex/Draft_Imperatives.pdf). The
WOAP suggested activity, coordinated by CEOP (T. Koike) and CMIP5 (Karl Taylor), isenvisioned as a collaborative effort of a broader observation and climate modeling communities
including GEWEX/CEOP, LandFlux-EVAL, GSWP, AsiaFlux, from the observation side. The
targeted dataset will consists of in-situ as well as satellite observations from multiple providers
including CEOP, FLUXNET, AsiaFlux, iLEAPS.
Consequently, the 10-Year Dataset project was discussed with the LandFlux-EVAL,FLUXNET, AsiaFlux, and GSWP representatives at the occasion of the HESSS2 Meeting inTokyo in June and it was agreed that a Whitepaper would have been developed and submitted
for discussion at the Pan-GEWEX meeting in August.
In this context the representatives of the sites that had been in operation since CEOP
Phase 1 were asked for kind cooperation on this task. These include Meyers (CPPA-Bondville),
Williams (SGP, ARM sites), Barr/Thompson (BERMS sites), and Horta/Araujo (LBA sites).
(3.1c) It was also reiterated that in order to demonstrate benefits of the CEOP special dataarchives it would be desirable to undergo an external review process that would clearly show thevalue that is added to the collected data including reference site and satellite observations
through the CEOP data format unification and data integration efforts. This step is necessary forassuring an adequate incentive for funding agencies to continue to support the CEOP data
activities. It was agreed that such external review was very important and reactivation of aninternational science and advisory group should be considered.
nd(3.1d) Benedict reiterated that the 2 Pan-GEWEX meeting would take place in Seattle, USA,
23 – 27 August 2010 (http://www.gewex.org/2010pangewex/home.html). The Pan-GEWEX
meeting will address how the GEWEX panels and their projects and working groups will continue
to work over the next 2 years to achieve their short-term goals, and how they will evolve toaccomplish post 2013 Imperatives. This process will include determining what enabling
infrastructure is necessary and developing a strategy for dealing with the GEWEX and WCRP
cross cutting or overarching themes.
According to the updated Pan-GEWEX agenda, each panel (including CEOP, GRP, andthth
GMPP) will have one and a half day (Tuesday 24 and Wednesday 25 morning) of separatethsessions dedicated to its own issues. A CEOP evening session on Thursday 26 August has
been added on the CEOP request. In addition, a half day for panel interaction is scheduled onthWednesday 25 afternoon. Further information including logistics details can be found at themeeting website.
Consequently, it has been noted that considering the outcomes the individual GEWEX
Panels including CEOP are expected to deliver at the Pan-GEWEX meeting, the available timemight not be sufficient to also address all the necessary CEOP internal planning issues to the full
extent. Accordingly, it has been decided that the Pan-GEWEX meeting CEOP sessions would notthfully substitute the 4 CEOP Annual Meeting event and that would be considered to take place
early in 2011.
3.2 Overall status of the CEOP reference site data archive and related issues(3.2a) Williams and Loehrer provided updated overall status of the Americas reference sitesthat is copied below in Attachment 1 and can also be accessed on the Internet at:
http://data.eol.ucar.edu/master_list/?project=CEOP/EOP-3/4.
(3.2b) Williams reiterated the ongoing action A2 on updating the site documentation/metadatathat all of the Reference site Managers and RHP Representatives were asked to undertake.

Namely, they should go on line to review all the documentation for their Reference sites that isavailable through the following web site: http://www.eol.ucar.edu/projects/ceop/dm/insitu/sites/
and to verify that it is complete and accurate and report necessary updates to Williams.
(3.2c) Williams also reiterated that the discussion in the CEOP model community and thedefinition of the scientific foci for the new CEOP period has resulted in the interest in / request for
additional data from the CEOP in-situ reference sites. This mainly covers three groups ofparameters: clouds, aerosol, and groundwater. It would be desirable if the Reference Site
Managers complete the survey and provide this information to the NCAR/EOL database. The online survey is located at: https://survey.ucar.edu/s?s=3003 and can be found through the DataManagement site at: http://www.eol.ucar.edu/projects/ceop/dm/questionnaires/.

is to provide a complete final product to all the requesting data repositories including the CDA,FLUXNET, and eventually NCDC at once and with supreme quality. Therefore the team isdedicating special efforts to the data quality control and gap filling procedures. Meyers indicatedthat part of the gapfilled and corrected observation datasets would be submitted to the CDA in
July.
(4.1d) Williams reported that the SGP sites data were almost complete up to 2009.
Nevertheless, he pointed out that there had been substantial changes in terms of individual
station locations (number of stations had been shut down and new would be installed in 2011) inorder to better fit to higher model resolutions. This needs to be considered when if the SGP site isnominated for contribution to the 10-YDP. It may require that a subset of stations is selected thathave been in operation at the same location since the beginning of the CEOP (or 10-YDP) period.
Williams also voiced that the ARM sites had also completed their data submission up to2009 and thus were good candidates for the 10-YDP.
4.2 LPB by Hugo Berbery(4.2a) Berbery reiterated that the LPB reference site Cruz Alta was working well and data werebeing collected. Debora Roberti, CPTEC, the Cruz Alta site representative for CEOP had sent
certain datasets to the CDA but several issues with the data were found and reported back toRoberti in April. The NCAR team is still anticipating a reply from her. It was proposed and agreed
that another note is sent to her from the NCAR team with a copy to Berbery, who would assist incommunication between Roberti and the NCAR team if necessary (action A3). The Cruz Alta site
documentation has not been submitted yet and is also requested.
(4.2b) Berbery further voiced that he and Dennis Lettenmaier attended the LPB meeting inArgentina in April 2010 visited two additional flux sites in the La Plata basin that have been in
operation since 1999 and planned to continue in observations and could possibly provide data to
CEOP.
Berbery also advised the group that an idea of a filed campaign in the basin had
emerged and been discussed among the US and Argentinean scientists, who were muchinterested in such activity. Berbery will inform the group of progress on this matter in due course.
(4.2c) Berbery also mentioned that the LPB community was very active, the most of theactivities
being
coordinatedbythe
CLARIS
LPB
Consortium(http://eolo.cima.fcen.uba.ar/~sweb/index.php), which is mainly funded by the European
Commission. The consortium involves about 20 Partners who contribute to international
Programmes or Projects, some have very strong links with stakeholders or governmental
decision-makers. Accordingly, the CLARIS LPB activities are carried out more independently,
similarly like in the AMMA RHP. It was noted at the call that while the work was being done on thebasin by the CLARIS group, it might be desirable for CEOP to focus on their reporting.
4.3 LBA by Luiz Horta, Alessandro Araujo(4.3a) Horta reported that the new person hired by on a full-time position for the LBA referencesite data processing had begun the work on the LBA data using a fully operational program andthus further data submissions from LBA might be expected in the near future.
He also voiced that a prototype system monitoring site sensors and transmitting data in
the real time that had been installed at the Manaus site would also be installed at the Santaremsite soon, which would expedite the data collection process.
Araujo reported that the 2006-2007 data from the Manaus and Santarem sites were
under preparation and would be submitted to NCAR soon.
(4.3b) Horta and Araujo mentioned that the possible candidates for the 10-YDP were Manaus
and Santarem sites. These sites have 11 years record of data, the longest-ever record in tropics.
Nevertheless, the LBA data policy restricts the data release, it is not allowed to provide the data
earlier than 1.5 year after observation/collection. Koike mentioned that the 10-YDP was in the
preparatory phase and the discussion on the data sharing/release would take place at higher
GEWEX management level after the Whitepaper has been presented, discussed, and revised
and the Pan-GEWEX meeting. Generally, the 1.5 year delay of the data release might not be anissue, depending on the exact 10-year period that is yet to be decided.

4.4 CliC BERMS sites by Alan Barr
Barr reported that the BERMS sites were working well and further datasets (beyond 2006) would
be processed and submitted to CEOP in the near future. He also mentioned that they would be
willing to contribute their data to the 10-year dataset.

NEXT CONFERENCE CALLth

The next, 7 CEOP Americas RHP and Reference Sites Teleconference is proposed to takeplace on Tuesday 12 October 2010 at 20:00 UTC. Benedict and Koudelova have the action(A1) to inform the group of the details of the next call nearer to the time of the call and tocoordinate the origination of the call (action A1a). In this context, a calendar of the dates andtimes of all the CEOP conference calls for 2010-2011 was distributed to the participants for their
future reference that is also available through the CEOP homepage at: http://monsoon.t.utokyo.ac.jp/ceop2/calls.html.

CEOP AND CEOP DATA GROUP GENERAL ISSUES(3.1a) Benedict welcomed participants on the call and appreciated the work that the Americas
RHP and reference site teams had undertaken in response to the action items from the last call.

(3.1b) Koike reiterated that a 10-Year Dataset project had been initiated in response to theclimate modeling community need of a high quality observation data of a sufficient length forevaluation of climate models under the CMIP5 project and quantification of model projections
uncertainties. This activity was proposed by the WCRP Observation and Assimilation Panelrd(WOAP) and is compliant with the CEOP commitment taken at the 3 Annual CEOP Meeting in
Melbourne in August 2009 to develop the CEOP 10-year dataset as well as with the GEWEX
post 2013 Imperatives (http://www.gewex.org/2010pangewex/Draft_Imperatives.pdf). The
WOAP suggested activity, coordinated by CEOP (T. Koike) and CMIP5 (Karl Taylor), isenvisioned as a collaborative effort of a broader observation and climate modeling communities
including GEWEX/CEOP, LandFlux-EVAL, GSWP, AsiaFlux, from the observation side. The
targeted dataset will consists of in-situ as well as satellite observations from multiple providers
including CEOP, FLUXNET, AsiaFlux, iLEAPS.
Consequently, the 10-Year Dataset project was discussed with the LandFlux-EVAL,FLUXNET, AsiaFlux, and GSWP representatives at the occasion of the HESSS2 Meeting inTokyo in June and it was agreed that a Whitepaper would have been developed and submitted
for discussion at the Pan-GEWEX meeting in August.
In this context the representatives of the sites that had been in operation since CEOP
Phase 1 were asked for kind cooperation on this task. These include Meyers (CPPA-Bondville),
Williams (SGP, ARM sites), Barr/Thompson (BERMS sites), and Horta/Araujo (LBA sites).
(3.1c) It was also reiterated that in order to demonstrate benefits of the CEOP special dataarchives it would be desirable to undergo an external review process that would clearly show thevalue that is added to the collected data including reference site and satellite observations
through the CEOP data format unification and data integration efforts. This step is necessary forassuring an adequate incentive for funding agencies to continue to support the CEOP data
activities. It was agreed that such external review was very important and reactivation of aninternational science and advisory group should be considered.
nd(3.1d) Benedict reiterated that the 2 Pan-GEWEX meeting would take place in Seattle, USA,
23 – 27 August 2010 (http://www.gewex.org/2010pangewex/home.html). The Pan-GEWEX
meeting will address how the GEWEX panels and their projects and working groups will continue
to work over the next 2 years to achieve their short-term goals, and how they will evolve toaccomplish post 2013 Imperatives. This process will include determining what enabling
infrastructure is necessary and developing a strategy for dealing with the GEWEX and WCRP
cross cutting or overarching themes.
According to the updated Pan-GEWEX agenda, each panel (including CEOP, GRP, andthth
GMPP) will have one and a half day (Tuesday 24 and Wednesday 25 morning) of separatethsessions dedicated to its own issues. A CEOP evening session on Thursday 26 August has
been added on the CEOP request. In addition, a half day for panel interaction is scheduled onthWednesday 25 afternoon. Further information including logistics details can be found at themeeting website.
Consequently, it has been noted that considering the outcomes the individual GEWEX
Panels including CEOP are expected to deliver at the Pan-GEWEX meeting, the available timemight not be sufficient to also address all the necessary CEOP internal planning issues to the full
extent. Accordingly, it has been decided that the Pan-GEWEX meeting CEOP sessions would notthfully substitute the 4 CEOP Annual Meeting event and that would be considered to take place
early in 2011.
3.2 Overall status of the CEOP reference site data archive and related issues(3.2a) Williams and Loehrer provided updated overall status of the Americas reference sitesthat is copied below in Attachment 1 and can also be accessed on the Internet at:
http://data.eol.ucar.edu/master_list/?project=CEOP/EOP-3/4.
(3.2b) Williams reiterated the ongoing action A2 on updating the site documentation/metadatathat all of the Reference site Managers and RHP Representatives were asked to undertake.

Namely, they should go on line to review all the documentation for their Reference sites that isavailable through the following web site: http://www.eol.ucar.edu/projects/ceop/dm/insitu/sites/
and to verify that it is complete and accurate and report necessary updates to Williams.
(3.2c) Williams also reiterated that the discussion in the CEOP model community and thedefinition of the scientific foci for the new CEOP period has resulted in the interest in / request for
additional data from the CEOP in-situ reference sites. This mainly covers three groups ofparameters: clouds, aerosol, and groundwater. It would be desirable if the Reference Site
Managers complete the survey and provide this information to the NCAR/EOL database. The online survey is located at: https://survey.ucar.edu/s?s=3003 and can be found through the DataManagement site at: http://www.eol.ucar.edu/projects/ceop/dm/questionnaires/.

RHP and Reference Site Reports

4.1 CPPA by Jin Huang, Tilden Meyers, and Steve Williams(4.1a) Huang advised the group that the NOAA's Climate Program Office was in the process ofrestructuring its grants programs (http://www.climate.noaa.gov/cpo_pa/). The grant activities are
now organized within four Programs, and the elements of CPPA are included in two of these,
namely the Modeling, Analysis, Predictions, and Projections (MAPP) Program and The Earth
System Science (ESS) Program. The CPPA observing activities are being funded through the
MAPP Program.
In this context, Huang mentioned that the NOAA CPO support currently provided to the
CEOP Data Management team at NCAR through the CPPA project would continue till the end of
2010. Since 2011, a new way through the MAPP Program will be sought.
(4.1b) Huang voiced that the 10-Year Dataset Project would be of high interest for the MAPP
Program and requested further details on this activity. It was mentioned that a Whitepaper on the
10-Year Dataset Project would be developed and submitted to the Pan-GEWEX meeting fordiscussion and revision.
(4.1c) Meyers reported in writing that they were are developing and testing a new gap filling
procedure in order to provide the best estimates of fluxes, including water and CO2, since these
are used to generated seasonal sums etc. for carbon and water budgets. They are using a
combination models that have been tuned to their data and have found this superior to standard
regression or statistical methods. The development and testing phase of this new procedure has
been completed and implementation will begin soon.
Certain problems have been found with the winter precipitation but correction has been
underway and almost completed. The team has also included both MODIS derived NDVI andtheir own in-situ NDVI that is tuned to get the seasonal trend in the LAI, which is very importantfor models. For 2010, three more variables will be added in the Bondville site dataset that include:(i) snow depth, (ii) fractional snow coverage, and (iii) in some cases, snow density. These aredetermined from the live internet PZT (Pan-zoom-tilt) camera installed at the site.
Regarding the data submission to the CEOP Data Archive (CDA) at NCAR, the team plan
is to provide a complete final product to all the requesting data repositories including the CDA,FLUXNET, and eventually NCDC at once and with supreme quality. Therefore the team isdedicating special efforts to the data quality control and gap filling procedures.
