CEOP AND CEOP DATA GROUP GENERAL ISSUES

3.1 WCRP and GEWEX related issues(3.1a) Benedict reported on the Pan-GEWEX meeting in Seattle, USA, on 23 – 28 August 2010
and its outcomes (http://www.gewex.org/2010pangewex/home.html). That event included a BusinessMeeting of CEOP and it was held in parallel with meetings of the other GEWEX Panels, namely, the
GEWEX Modeling and Prediction Panel (GMPP) and the GEWEX Radiation Panel (GRP). Following
the Plenary sessions and the parallel Panel meetings the GEWEX Scientific Steering Group (SSG)
also met.
The outcome of these events included a number of decisions, recommendations and actions
specifically associated with CEOP as well as a set of general (Pan-GEWEX) actions for all the
Panels. A still preliminary summary of key events that took place at both the PGM and the SSG
Meeting as submitted by the SSG Chairman Dr Kevin Trenberth is attached below(ATTACHMENT2). This document was distributed to the broader CEOP community subsequently
after the call together with a list of actions drafted at the end of the SSG Meeting.
The main changes that have taken place recently with respect to CEOP include:
1. The SSG accepted Prof Toshio Koike’s decision to step down as Co-Chair of CEOP effectiveat the close of the PGM at Seattle. This action, followed Dr Ron Stewart’s resignation, which
was taken at the close of the SSG meeting at New Delhi India, 25-29 January 2010,
2. Dr Dennis Lettenmaier was named Co-Chair of CEOP to replace Dr Stewart, effective at theend of the SSG meeting at India (25-29 January 2010),
3. There is a search team being organized to find a Co-Chair to work with Dr Lettenmaier,
4. The SSG agreed to change the name of CEOP to the GEWEX Hydroclimatology Panel(GHP), effective immediately following the end of the PGM,
5. HyMeX (HYdrological cycle in the Mediterranean Experiment, http://www.hymex.org/) wasapproved as an official GEWEX/GHP RHP by the GEWEX SSG.
Also a new set of criteria for GEWEX RHPs was proposed at the meeting that were circulated prior tothe call and that should be reviewed by RHPs. It was pointed out that the current GHP (CEOP) RHPs
would be evaluated according to the new criteria but it is an evolving process targeting the year 2013
when also the new GEWEX Imperatives should be in full implementation.
In addition, Benedict voiced that with regards to the changes resulting from the Pan-GEWEX meeting
discussions, the data collecting and reporting scheme may need some restructuring, however the2

urgent need for a high quality data as a basis for scientific activities that are key for the GEWEXImperatives was confirmed at the meeting and the reference site data activities are supposed tocontinue in a certain manner. The in-situ data from the CEOP reference sites were acknowledged andstudies based on these data were presented at the meeting. Benedict further voiced that the GEWEX
Office agreed that the CEOP datasets including the reference site data should remain CEOP legacy
as a CEOP contribution to WCRP/GEWEX objectives.
The group was also advised that a GHP advisory panel was being established that would advise andreview the panel activities. In addition, an RHP council will also be set up that will focus on interaction
between GEWEX (GHP) and RHPs.
(3.1b) The group was informed that efforts to develop a new RHP in USA/Northern America had
been initiated and preliminary planning was ongoing. The idea is to build on the success of the
GCIP/GAPP/CPPA legacy, while entraining the vast array of interdisciplinary observational andmodeling resources available in this region. Through smart coordination and integration, it is intended
to coalesce an interdisciplinary, interagency, and potentially international effort that will makesignificant contributions to continental-scale hydroclimate science and solutions. It is seen as acontribution to not only GEWEX but also the broader climate, carbon, ecology, and applications
communities. A town hall meeting on this matter is scheduled at the AGU Fall meeting in San
Francisco, Wednesday 15 December, 1230h–1330h and anybody attending the AGU meeting andinterested in this idea is welcome to this event.
(3.1c) It was reiterated that a 10-Year Dataset project had been initiated in response to the climate
modeling community need of a high quality observation data of a sufficient length for evaluation ofclimate models under the CMIP5 project and quantification of model projections uncertainties. This
activity was proposed by the WCRP Observation and Assimilation Panel (WOAP) and is compliantrdwith the CEOP commitment taken at the 3 Annual CEOP Meeting in Melbourne in August 2009 todevelop 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 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
GHP (CEOP), FLUXNET, AsiaFlux, iLEAPS.
The 10-Year Dataset project was discussed with the LandFlux-EVAL, FLUXNET, AsiaFlux, and
GSWP representatives at the occasion of the HESSS2 Meeting in Tokyo in June and subsequently aWhite Paper was developed and submitted for discussion at the Pan-GEWEX meeting in August (see
ATTACHMENT 3). The activity was accepted as one of the new GHPs efforts. The White Paper is
now being discussed with the CMIP group and the GHP (CEOP) community will be informed of thefurther development of the activity in due course.
With regards to the 10-year period, the actual years have not been confirmed yet. In this context, it
was mentioned that processing the data prior 2001 would mean a non-negligible additional effort,
which should be considered when deciding the actual 10-year period. Williams also added that thenomination of sites would be done by an advisory group that is to be formed and that the geographicaland climate aspect of the sites will also be considered together with the completeness of the data
record for the selected 10-year period.
(3.1d) It was reiterated that Prof. Koike met Prof. ZHENG Guoguang, CMA (China Meteorological
Administration) Administrator and Dr. ZHAO Datong, Deputy Director-General, Department ofthIntegrated Observation, CMA in Beijing on 26 July and also during the GEO Ministerial Summit inNovember and discussed with them the permission for the Chinese reference sites to provide the data
to CEOP (GHP). Prof. Koike introduced the essence of the CEOP activities and the high value andmerit of the unique CEOP dataset and explained the need for in-situ observation data from the
Chinese sites and requested the CMA to grant the permission to the reference sites in question toprovide their observation data to CEOP, while adhering to the CEOP Reference Site Data Policy.
This was the first time the CMA leaders were officially and in detail informed of the CEOP dataset
specifics and merits and CEOP activities. They recognized its value and contributions to the energy
and water cycle research and understood the need for the data from the Chinese reference sites and3

would consider the CEOP's request accordingly and with regards to the GEO Ministerial Summit in
Beijing in November 2010.
Dr. Zhao Datong has kindly agreed to play a key role of mediator between the responsible persons of
CMA and the site managers, for finalizing the permission of the data submission to the GHP (CEOP).
The managers are asked to provide lists of observed parameters that are to be provided to CEOP.
The parameters will be divided into two tables depicting (a) physical parameter and (b) chemicalparameters. The CMA will consider individual parameters based on the provided lists.
In this context, the site managers of the Chinese reference sites have action A2 to contact Dr. Zhao
Datong in this matter as soon as possible.

beginning of September and was available for download at:
http://www.gewex.org/2010pangewex/home.html.
(3.1f) The group was informed that the data portal of the Data Integration and Analysis System(DIAS) of Japan was opened to public on 1 October 2010 that can be accessed at:
http://www.editoria.u-tokyo.ac.jp/dias/link/portal/english_index.html.
3.2 Overall status of the CEOP reference site data archive and related issues(3.2a) Williams provided updated status of the sites that submit their data directly to the NCAR/EOL
in the requested format and quality-checked without using services of the CEOP_AP data center at
Tokyo, Japan. These sites include: Himalayas, Pakistan, Tsukuba (Japan), Australian, and Italiansites. The update included:- CEOP_AP Himalayas - FLX - complete through 2008
- CEOP_AP Himalayas - SFC - revised version through 2008 checked and will be uploaded soon
- CEOP_AP Himalayas - STM - revised version through 2008 checked and will be uploaded soon

- CEOP_AP Tsukuba – issues communicated with Ken’ichi, data may be uploaded soon.
- Italy – quality check completed and issues sent to Roberta/Elisa.
- MDB Murrumbidgee - SFC and STM complete through 2007.
- MDB Tumbarumba - FLX, SFC and STM (2002-2009) data were checked back in April and issues
were sent to Jason/Eva.
The overall status can be accessed on the Internet at:
http://data.eol.ucar.edu/master_list/?project=CEOP/EOP-3/4.
(3.2b) Tamagawa could not attend the call but circulated the updated status of the CEOP_AP data
center prior to the call. The summary table is included in ATTACHMENT 1 below. Koudelova
introduced the summary and the respective site representatives, who attended the call, confirmed thedata status and provided further details.

In this context, it was reiterated that out that the Himalayan site Syangboche station and the
Tsukuba site new NIFTS station were missing on the detailed list of Asia Pacific sites and theirindividual stations that is included in the referred Excel file showing the status of the CEOP_AP data
center. In addition, it was suggested that the site representative names be added to the table on
relevant rows. Tamagawa has action A3 to update the list and the table accordingly.
It was also reiterated that with regards to the large number of the sites and individual stationsin the Asia-Pacific region and the established process of submitting the data to the CEOP_AP data
center at the University of Tokyo first in case of most of the sites, the CEOP_AP data management
group led by Tamagawa request the site managers for interim reports in between the calls and informthe CEOP Data Management team at NCAR accordingly (action A3a).
(3.2c) A question was raised about availability of the MOLTS (model output) data for the referencesite locations. These data is essential for comparison and evaluation studies at the sites and site
representatives are interested where and when the data will be available. Koudelova mentioned thata number of MOLTS datasets should be available at the MPI archive and took action A4 to ask about
the current status Frank Toussaint at the MPI team.

RHP/REFERENCE SITE REPORTS

The following reports include (i) inputs, which were sent in by persons who could not participate in thecall, (ii) contributions, which were put together from the written and oral inputs provided by those who
did participate in the call, and (iii) oral reports of those, who did participate in the call but did notprovide the written input.
4.1 MDB RHP and Reference Sites by J. Evans
It was reiterated that several papers focused on the MDB were in the submission/review process at
refereed journals.
The observation at the MDB sites continues well. The issues found in the Tumbarumba towerdatasets are being discussed with the data provider. Instrumentation for the new Wellington site had
begun. Currently groundwater is being monitored through a number of wells with others still being
dug. The bulk of the surface and atmospheric instruments are due to arrive and be installed over the
next ~3 months.
4.2 Himalayas, Pakistan Karakorum, and Italian sites by the Ev-K2-CNR group (Tartari, Toffolon)
The Himalayas and Pakistan AWSs are regularly functioning and maintenance operation and data
downloading are regularly carried out. At present, all the sites are performing continuous
measurements correctly. New data loggers are being installed at the Khumbu valley station to
improve data recording and enable transmission in real time. This upgrade should be completed inspring 2011.
The Himalayas and Pakistan 2008 datasets have been submitted and are in process at NCAR as
mentioned by Williams above. The 2009 datasets are being checked and will be submitted to NCARin the near future.
Tartari advised the group that the value of data from the Khumbu valley (Himalayas) stations foradvanced research of atmospheric physics was recognized and new collaborative activities exploitingthese data have been discussed by the Ev-K2-CNR Committee. Also the data from the Pakistan
stations have been evaluated and a report issued at the end of October.
4.3 Mongolia site by Ichirow Kaihotsu – written report
All the AWS stations of GHP (CEOP) in the Mongolian plateau are working well. The monitoring for
GHP will continue and the data is being processed54.4 Tsukuba site by Ken’ichi Ueno
The Tsukuba site data up to 2008 have been corrected according to the NCAR comments andchecked and can be uploaded to the NCAR archive. The 2009 data have also been corrected basedon the comments and are now being checked and will be available soon. The 2010 data are being
collected and checked and will be processed for GHP (CEOP) in due course.
4.5 Indonesian sites by Jun’ichi Hamada and Hideyuki Kamimera (written report)
Hamada mentioned that the 2007 dataset of Kototabang station in the Western Indonesia site has
been sent to NCAR by this call. The metadata document as well as the MIA station dataset is being
prepared and will be provided to NCAR soon.
The 2008/2009 data from all the sites (Western/Central/Southern/Eastern/Northern Indonesia) havebeen collected and are being prepared for uploading into the QC system of UT. Hamada noted thatobservation in Northern Indonesia site was started in January 2009.
Kamimera added that currently, the "2nd-step" quality check of 30-minutely data for two years (2008and 2009) obtained from MIA AWS was being performed using QC system at UT. The elements are
solar radiation, air temperature, relative humidity, surface pressure, and rainfall amount. Two otherstelements, wind direction and speed, are still being under the “1 -step” quality check of minutely raw
data and will be converted into 30-miunte CEOP format and uploaded to the UT system in the nearnd
future. The 2 -step quality check will then be performed.

4.6 Northern Mongolia site by Jun Asanuma – written report
Observations at the site in the forest, which is one of the surface stations in Northern Mongolia, havebeen stopped since 2006 when the solar panels were stolen. Instruments and loggers have been left
at the site, having hoped for restarting the observation. In the summer of this year, the site was foundto be totally destroyed, all of the valuables, even those under the ground, has been taken leaving only
the tower itself. Therefore, sadly, the official termination of the observation at the forest site has been
declared.
In the meantime, the observation at the grassland site is going well. Currently, the quality control of
the observation is being performed and it has been found that there was a systematic bias in the
precipitation records. The bias is being corrected using the operational observation nearby. (off-line
comment: a proper flag must be applied to mark the corrected data).
In summer, a new project was started on the intercomparison of the land surface schemes at the
Asian drylands. The project, called ADMIP, Asian Drylands land surface Modelling Intercomparison
Project, aims for observation-based intercomparison, and the target sites include the grassland site of
the Northern Mongolia, as well as Tongyu, and others at Lanzhou in China. Sixteen models, including
land surface models and ecosystem models, have already registered. Currently, the forcing data outof observation are being prepared, and we still welcome the new participation of models.
4.7 Tibet site by Hirohiko Ishikawa and Zeyong Hu
Ishikawa reported that the latest available datasets from the Tibet site were being checked by theirown system, however the action was delayed due to lack of manpower. Ishikawa is seeking a person,
who will assist with this process.
Ishikawa further reported that they were enhancing the observation stations in Tibet, currently 3
turbulence systems were in place.
Ishikawa introduced Dr. Zeyong Hu, CAREERI, Lanzhou, China, who has become a new site mangerof the Tibet reference site and agreed to participate in these GHP (CEOP) conference calls to advise
the group of the latest developments at the site. Participants welcomed Dr. Hu on the group andacknowledged his support of the GHP (CEOP) activities.

4.8 Western Tibet site by Shigenori Haginoya
Haginoya reported that no new data have been received form Chinese Academy of Meteorological
Sciences (CAMS) since November 25th 2008 and it is not sure when the new data from China can be
expected. Also the present status has not been reported by the Chinese side for a longer period andthus it is suggested that a representative from the Chinese team joins this teleconference group.
The work on the available data is progressing but has not been completed yet.
4.9 Heihe river basin site by Wu Yueru and Zhi Zhihui – written report
All of the stations are running well, and data are collected and disposed well too. However, due to thepolicy, we have no right to upload the data, and this matter is still under discussion. Data on thereference site website has not renewed since the last call but it will be done in the near future.
Regarding the Heihe river basin reference site documentation, it has been updated on the CEOP DataManagement Page and confirmed by the Heihe river basin team.
4.10 Northern South China Sea - Southern Japan site by Mike Chen
Chen reiterated that the data from the beginning of 2005 through the end of 2008 had been uploaded
to the CEOP_AP data center at UT and the quality check and metadata generation were almost
finished. He referred to the updated status prepared by Tamagawa.
In addition, Chen reported that a special experiment focused on the monsoon activity that was onschedule this year and consisted of two components: (i) winter monsoon and (ii) summer monsoon,
could not begin due to certain political issues that prevented shipping and installation of measuring
instruments. The team is hoping that the issues will be resolved in time for the winter campaign
otherwise the experiment will have to be abandoned because it has already been postponed due toatypical weather conditions as reported during the last call.
4.11 Central Vietnam sites by Hideyuki Kamimera – written report
The "1st-step" quality check is underway of minutely raw data for 1.5 years (from March 2009 toAugust 2010) obtained from Da Nang AWS.
http://www.jamstec.go.jp/iorgc/harimau/kamimera/tmp/dan/Conversion of raw data into 30-minutely data will follow and after doing this, all the elements will be
uploaded into the QC system and the "2nd-step" quality check will be done.
4.12 Siberia and Mongolia Nalaikh sites by Hironori Yabuki
Yabuki confirmed the status of the Siberian sites data as reported by Williams and Tamagawa andvoiced that their group was working on further datasets (beyond 2007). The sites are operating well.
Regarding the Mongolia Nalaikh site, there has been a damage on the observation equipment due toa thunderstorm in May and it was only repaired in October during a field trip. Therefore, the data arelost from May through October 2010, otherwise the site is operating well.
Yabuki also reiterated that the Mongolia Arvayheer site was destroyed in 2008 and the decision wasmade not to rebuild it and thus it should be removed from the list of GHP (CEOP) reference sites.
Tamagawa and Williams have action A5 to modify their reference site lists and website accordingly.
4.13 MAHASRI update by Jun Matsumoto – written report
Project management has been conducted personally by the project leader, Prof. Jun Matsumoto ofTokyo Metropolitan University and JAMSTEC/RIGC with supports both from domestic andinternational steering groups, and domestic advisory groups. We have no project coordinators.
MAHASRI Web page has been open to international public but not very actively maintained.

7

The community has been collecting hydroclimate data mainly from Southeast Asian countries andparticipating projects. Since the poor support for the data management, the data opening has not yet
been fully started. Hopefully it will start from early next year.
CEOP in-situ reference site data have been maintained by each participating data manager and all
the data have been open.
The community has been actively contributing to the Pan-WCRP crosscutting Asian Monsoon Years
2007-2012 project. The intensive observation data for contributing MAHASRI and AMY will be openfrom AMY Data Center at the University of Tokyo from the next year (2011). Also AMY Re-analysis
data included AMY IOP data for the period 2008-2009 (or 2010) will be conducted by MRI-JMA fromthe next year.
A JMSJ Special Issue on MAHASRI is now being edited. A number of foreign editors were invited tothis issue's editorial board members from AMY community. The editing processes are now nearly at
the final stage. In total 25 papers will be published with approx. 350p volume in late January 2011.
The International Workshop on Climate Changes in Asia will be held at Bangkok in 6-7 January, 2011.
The YOTC International Science Symposium will be held in May 16-18 2011 at Beijing, incollaboration with AMY. Vietnam-Japan International Workshop will be organized in August 2011 in
Vietnam. International AMY Science Conference will be held in November 2012 in China, probably at
Guilin.

Outcome and prospects from the August 2010 pan-GEWEX and SSG meetings, Seattle.
Kevin E Trenberth
GEWEX held a “pan-GEWEX” meeting in Seattle for a week in late August 2010. The “pan-GEWEX” connotation means that it
was an opportunity for all of the working groups and panels within GEWEX to meet together and exchange views while interacting
to formulate future plans. Accordingly, the Scientific Steering Group (SSG) attended and participated fully, and we took theopportunity to have an SSG meeting after the full meeting closed. In addition, a number of program managers from different
nations attended, and we were fortunate to be able to involve a number of young scientists in the process (see report elsewhere).
This pan-GEWEX meeting was especially eventful owing to a number of challenges before the community in formulating plans forthe new post-2013 phase of the WCRP, guided by the JSC. In particular, the guidance suggested that core projects would be
retained but with revised responsibilities to facilitate climate system research at the interface of the physical Earth systemcomponents. The suggested four new core projects should be: 1) Ocean-atmosphere (think CLIVAR); 2) Land-atmosphere (think
GEWEX); 3) Cryosphere (think CliC); and 4) Stratosphere-troposphere (think SPARC). Then within each core project there should
be a common set of basic “themes” including 1) Observations and analysis; 2) Model development, evaluation and experiments; 3)
Processes and understanding; 4) Applications and services; and 5) Capacity building. Coordination across projects on these
themes would be via WCRP Modeling and Observations Councils.
In preparation for the forthcoming changes, prior to the last JSC meeting, the GEWEX SSG met in January 2010 in New Delhi andbegan formulating plans for the future via a new mission statement, a set of imperatives (things that must be done), and a set offrontier challenges for the future. The draft set of these was published in the May 2010 GEWEX newsletter as a basis for the panGEWEX discussions.
At the January meeting, I had challenged the SSG to say why the three GEWEX panels: Radiation (GRP), Modeling (GMPP), and
CEOP should be together. The arguments were strong and convinced me that we should continue with similar components in any
future GEWEX. Figure 1 illustrates the points from the standpoint of the hydrological cycle, featuring radiation, atmosphericprocesses and land surface hydrology and processes. The original motivation for these being together is that they correspond to
the “fast” processes in the climate system, and this still applies. Following the JSC meeting in February, key questions were “howmuch science falls under land-atmosphere” and “what about those that do not?” Accordingly, the approach taken in the panGEWEX meeting was that while the future GEWEX should indeed be the place where land-atmosphere interactions were featured,it should be much more. In particular, it should retain the global energy and water cycle as a core focus while adding regional
aspects. It should indeed also feature hydrological and land surface processes and modeling, and interactions with theatmosphere. However, it should further retain a strong atmospheric component related to the water and energy cycles, and hence
scientific issues related to radiation, clouds, convection, precipitation, boundary layers, surface fluxes, runoff, and human
influences which should also be included in terms of observations, process understanding and modeling.

Fig. 1 depicts the hydrological cycle schematically and thus the driving by radiation and energy, the atmospheric dynamics thatmove water and energy around and produce clouds which block the sun, the complex land surface complete with human
influences and the interactions with the atmosphere, and the surface and below surface processes that complete the water cycle(adapted from Trenberth et al. 2007).
The meeting provided a venue for vigorous discussions of the draft imperatives and the future directions for GEWEX. Following
the meeting, the SSG has decided on the following. 1) While the old GEWEX name was liked by many for its uniqueness (e.g., in agoogle search) and name recognition, no-one has come up with a viable alternative for the “EX” part that is clearly obsolete.
Accordingly, the new name post-2013 is suggested to be: “Global and Regional Energy and Water” (GREW). This has many
aspects in common with the old name and the two should be used together for a period of time. The revised mission statement is:
To measure and predict global and regional energy and water variations, trends, and extremes (such as heat waves,
floods and droughts), through improved observations and modeling of land, atmosphere and their interactions; thereby
providing the scientific underpinnings of climate services.
There were strong sentiments for fewer more succinct imperatives, and the following seven have been approved by the SSG:
Datasets: Foster development of climate data records of atmosphere, water, land, and energy-related quantities,
including metadata and uncertainty estimates.
Analysis: Describe and analyze observed variations, trends and extremes (such as heat waves, floods and droughts) inwater and energy-related quantities.
Processes: Develop approaches to improve process-level understanding of energy and water cycles in support of
improved land and atmosphere models.
Modeling: Improve global and regional simulations and predictions of precipitation, clouds, and land hydrology, and thus
the entire climate system, through accelerated development of models of the land and atmosphere.
Applications: Attribute causes of variability, trends and extremes, and determine the predictability of energy and water
cycles on global and regional bases in collaboration with the wider WCRP community.
Technology transfer: Develop diagnostic tools and methods, new observations, models, data management, and otherresearch products for multiple uses and transition to operational applications in partnership with climate and hydrometeorological service providers.
Capacity building: Promote and foster capacity building through training of scientists and outreach to the user
community.
The header in each case highlights the link between the imperative and the themes outlined by the JSC. There is still much to bedone to flesh out these imperatives with more details about what they mean in terms of the actions to be taken, the lead groups in
GEWEX and interactions with other parts of WCRP, and the other organizations involved.
Modeling
Prior to the pan-GEWEX meeting, extensive discussions had been held by email that set the stage for the discussions in Seattle.
These arose in particular from a desire for the chair of GMPP (Christian Jakob) to step down and a proposal to remove the layer of
GMPP, as well as the need to address the future structure of GEWEX and GEWEX modeling post-2013. The many questions andstatements that arose were summarized as a series of questions, mostly related to modeling, that were appended to the panGEWEX meeting agenda. Based on those discussions, I offered some proposals for how this may move forward that turn out tobe similar to those adopted.

11

The proposal of removing the GMPP layer between GCSS, GABLS and GLASS with the SSG met with strong approval. Instead
GCSS/GABLS will be combined and, along with GLASS, will report to and take advice from the SSG directly.
This proposal was subsequently approved by the SSG.
As a consequence of the removal of the GMPP layer there is a need for GCSS/GABLS to undergo some reorganization. This will
also pave the way for the post-2013 transition. As a result of the discussions it was proposed that GCSS abandons its current
Working Group structure. Instead, the group will operate through projects. Those can be initiated by any member of thecommunity. A Science Steering Committee (SSC), which will form the GCSS/GABLS Panel, will be responsible for the successful
running of the program. This includes the approval of proposals as well as engagement with the community to explore newopportunities. The GABLS activities will be fully integrated into this structure through GABLS-specific projects as well as GABLS
membership on the SSC. The GCSS and GABLS brand names will be maintained. This proposal was also subsequently approvedby the SSG.
Most of the discussion in the group was about the extension of the current atmospheric model development activities in the post2013 structure. This resulted in the proposal for a Framework for Atmospheric Model Enhancement (FAME). The mission of
FAME is proposed as: Improving the representation of physical and dynamical processes in the troposphere in models for all
purposes and especially weather and climate services. Its main focus would be the improvement of the representation of clouds
and precipitation in atmospheric models, which can only be achieved by improving our understanding of the intricate coupling ofphysical and dynamical processes associated with clouds and precipitation at various scales.
FAME was proposed in recognition of need expressed by the IPCC in several reports which highlighted the significant
shortcomings in models in the simulation of clouds and precipitation with consequences for the simulation of important climate
feedbacks and climate sensitivity. Other important factors included the recent revolution in the ability to observe clouds andprecipitation, especially from space, and improvements in ability to model the processes involved at the process-scale. The
experience of more than 15 years of the GCSS program and almost 10 years of the GABLS program makes the time right for amore concerted effort in atmospheric model improvement that builds on the existing strengths and adds to them the important new
research area of physics-dynamics coupling.
The envisaged ingredients of FAME would be programs on the PBL (GABLS), clouds, convection and precipitation (GCSS),
radiation (currently residing in GRP and SPARC), coupling to dynamical processes (new) and potentially also coupling to numerics(new). FAME will be built around the core approaches identified by the WCRP JSC, e.g., observations, modeling, data analysis
and model diagnosis, and process studies. Through the direct involvement of operational modeling centers in FAME as well as
through the engagement of scientists throughout the world, the activities in FAME will make major contributions to capacity building
and services.
As FAME is tightly focused on providing a means for the improvement of the representation of core physical processes inatmospheric models, it will partner with many other programs to contribute to the research on phenomena that go beyond thephysics-dynamics coupling in the atmosphere. Those include partnerships with the land (e.g., GLASS, GHP), ocean (e.g.,
CLIVAR), aerosol (e.g., ACPC, iLEAPS), atmospheric chemistry (e.g., SPARC, IGAC), stratosphere (e.g., SPARC), andcryosphere (e.g., CliC) communities. Necessarily, these go well beyond GEWEX alone.
FAME could be seen as a natural extension to the existing GCSS/GABLS panel described above, if the post-2013 GEWEX
structure still allows for such an activity. This would maintain continuity, provide close links to the land and limited area modelingcommunities and ensure FAME’s natural focus on the energy and water cycles. These activities were originally grouped together toprovide a focus on relatively “fast processes” as compared with those involving the ocean or cryosphere. FAME could also make amajor contribution to a potential cross-WCRP effort on atmospheric model development.
This proposal was subsequently discussed by the SSG who strongly recommend keeping FAME within the post-2013 GEWEX
structure. Questions include how FAME goes forward, whether as a panel or working group. Many of the other modeling activities
in WCRP come under working groups. WGSIP is an example where the WG reports to the CLIVAR SSG but acts on behalf of the
WCRP to deal with seasonal to interannual prediction. A new group, integrating FAME and possibly called WGAP, short for WG
on Atmospheric Processes and modeling for climate, could operate similarly within the new post-2013 GEWEX. However, as theactivities relate to the established WGs, especially WGNE, this aspect is yet to be decided after broad consultation with thecommunity.
Land surface and hydrological science
Major changes were also underway in the realm of the regional hydrological projects at the pan-GEWEX meeting. In part thesecame about naturally from the evolution of the program, and given extra nudge by the change in leadership. Under the leadershipof Toshio Koike, CEOP developed an impressive and extensive program, including the Regional Hydrometeorological Programs(RHPs), associated modeling and data base development, and the Hydrologic Applications Project (HAP). CEOP remains at thecore of the GEWEX mission, includes more than a thousand researchers, and provides important regional data, modeling and avaluable end-user interface.
The brief history is that the Continental Scale Experiment (CSE) concept was developed in the 1990s. Its purpose was thedevelopment, diagnosis, and testing of coupled land-atmosphere models with a focus on water and energy budget closure at nearcontinental scales. An example was the GEWEX Continental Scale International Project (GCIP) for the Mississippi basin as a well12

instrumented and analyzed region. This led in turn to the development of RHPs to extend this concept to other regions: MAGS,BALTEX, GAME, LBA, AMMA; and even more recent RHPs, see Figure 2. The panel set up to provide coordination and oversightwas the GEWEX Hydrometeorological Panel (GHP). Then to take advantage of many new satellite and other observations the
Coordinated Enhanced Observing Period (CEOP) was begun in 1995 and continued into the second phase of GEWEX for
2001-2006. This activity, which also developed extensive data management activities, led by Toshio Koike in Japan, also led tosome similar panels to those in GHP and some duplication of effort. Accordingly, this first CEOP activity was combined with GHP
and evolved to become the Coordinated Energy and Water Cycle Observations Project with the same acronym, CEOP, in
2007-2008. The initial observing period grew to become a move to produce a 10 year dataset and archive especially set up for theregional projects. However, other developments had already occurred in observations and data management, which suggested
the activity should be wrapped up and refocused, even as it is utilized and hopefully becomes part of the heritage of GEWEX. In
particular, the development of the many flux towers around the globe provide alternatives to the CEOP reference sites for local
studies of energy, water and biogeochemistry.
Accordingly, the community began what might be called a “back to basics” movement, with recognition of the need to reinvigorate
the regional hydrological projects. In particular there was a call by the new co-chair, Dennis Lettenmaeir, for stronger hydrologicalactivities which would foster the next generation of hydrologically realistic land surface schemes and provide a home for projects
like PILPS. The recommendation to the SSG was along these lines and thus a new GEWEX Hydroclimatology Panel (GHP: notethe change in the name from the first version) has been formed to replace CEOP, effective immediately. The SSG also followed
up on the recommendation from CEOP to approve a new RHP called the HYdrological cycle in the Mediterranean Experiment(HyMeX), focused on the 20 countries around the Mediterranean Sea and the fresh water and salinity of the Sea itself.
GHP is thus the home for hydrologic science and modeling within WCRP and there is considerable scope for developments in thisarea, e.g. in seasonal forecasting, the detection and attribution of change, and the development and analysis of climate
projections. Challenges remain in dealing with monsoons and to help coordinate the multitude of national initiatives in this area.
There are also opportunities for linkage with GLASS in bringing disciplines together in the development of next generation Land
Surface Models as well as increasing interactions with CORDEX. Changes in the management structure are likely to accompany
the new consolidation of efforts as GHP realizes its considerable potential.

GEWEX Datasets
The original GEWEX datasets were developed under the auspices of the GEWEX Radiation Panel (GRP) which continues, but isalso looking for a name change as it does a lot more than radiation. It does deal with all of the global satellite data related toenergy and water and their synthesis into products, and is currently leading and promoting reprocessing of the datasets with a goalof creating climate data records of sufficient quality to be useful for examining trends. Some of the datasets, such as GPCP and
ISCCP, are well known and already used extensively, but the scientists are confident that they can be made much better and moreconsistent with each other, and with better estimates of uncertainties.
In general GRP is working well toward the new goals and has produced simulators, that take into account the sampling andcharacteristics (such as thresholds) of the observations to enable intercomparisons of satellite products with model data.
Interactions with other parts of GEWEX were fostered by the pan-GEWEX meeting, and the GEWEX datasets have potential for

13

great use in evaluating and improving models on issues such as clouds and indirect effects of aerosols, precipitation frequency,
intensity and amount, and in providing the context for the RHPs.
Extremes
The recent summer record breaking flooding in Pakistan, India and China, and heat-waves and wildfires in Russia highlight theextremes of the hydrological cycle of drought and floods that are changing from human activities. Dealing with extremes in WCRP
is a cross-cutting activity that involves all projects although GEWEX plays a leading role. Olga Zolina, who is a member of the
GEWEX SSG, led the WCRP extremes workshop involving some 150 people at UNESCO in late September. Breakout groups
were held on issues of 1) data requirements and availability (such as the need for hourly precipitation data to properly characterize
extremes); 2) representation of extremes in models, including scaling and spatial issues (how station data relate to grid squares,
comparing apples to apples); and 3) methodologies for estimating extremes across areas and disciplines, including statisticalmethods. Continuing issues are sorting out the human changes in extremes and how to best communicate with the general public
on such technical attribution issues.
For instance, it is likely that the southeast Asian floods and the Russian drought were linked by the monsoonal circulation andteleconnections linked to the anomalous latent heating of the atmosphere associated with the heavy rains. The pattern of the rains
was related to the rapidly developing La Niña but the previous El Niño had left behind a residue of abnormally high sea surface
temperatures in the Indonesian-northern Indian Ocean region that provided an enhanced supply of moisture to the monsoon rains.
No doubt those elevated temperatures have a global warming component. The persistent “blocking high” over Russia led todrought that was no doubt more intense and longer lasting owing to global warming, with increased risk of heat waves and wild
fires. While these connections are very likely, they are hard to prove as models do not reproduce monsoon rains very well, andblocking is poorly simulated. These scientific challenges extend across the WCRP.
Closing remarks
The above is but a sample of the goings on and developments from the pan-GEWEX meeting. What I have tried to do is provide asense that we are looking forward to the future with considerable excitement at the science we can achieve through collaborationand friendly competition, with the help of coordination through GEWEX and, in the future, GREW. I would like to thank all of those
who attended and participated.

ATTACHMENT 3
Whitepaper on 10-year dataset development(Draft ver. 0.2, 23 July 2010)
1. Background
Climate change poses a fundamental threat to the well-being of the people all over the world. This threat encompasses security inwater, food, energy and health. Climate change is not hypothetical, and its impacts are already evident, as both scientificobservations and the experiences of the region’s inhabitants confirm. And in confronting the risks and challenges posed bychanging climate, we must acknowledge the fundamental uncertainty in our projections of future climatic and water resourcesconditions, and work to improve our ability to identify effective responses while reducing this uncertainty.
2. Mission
To reduce the uncertainty, a simple framework to identify, organize and disseminate comprehensive, quality and long-term
observational datasets should be provided to modeling communities, e.g. Coupled Model Intercomparison Project phase 5(CMIP5), and analysis and impact study research groups.
In response to this need, the 10-year dataset project (Project) aims to develop a high-quality comprehensive dataset of
meteorological and hydrological variables for a selected 10-year period based on most advanced and complex land reference sites
distributed over the world and complemented with relevant satellite observations. The targeted dataset will be “homogeneous”
across data providers and individual sites, i.e. of a standardized format, fulfilling high quality requirements in accordance with
CEOP standards, and equipped with appropriate metadata assuring full interoperability and “easy” use.
In this way, the Project mission is in concert with the GEWEX Post 2013 Mission Statement and Imperatives. It responds to theimperative to develop climate data records of atmospheric and land variables, complete with metadata and error bars, in particularthrough development of appropriate calibration/validation/evaluation datasets to confront models. The Project will build on the
CEOP experience in data management, archival and access, while devising robust ways of dealing with the more diverse, complex,
higher spatial and temporal resolution, and much greater volumes of data.
The targeted dataset contribution
1. Climate studies

14

Evaluation of the climate model output applicability for climate change impact assessment (CMIP5).
2. Societal needs
Quantification of uncertainties of model predictions/projections and thus making the model output information useable for decisionand policy makers.
3. Scientific community
The dataset will also be usable for scientific community to further advance research into energy and water cycle processes. It willcontribute to several GEWEX imperatives focusing on analysis and model development and improvement. These include:- Increase understanding of energy and water cycle processes, quantify their contribution to climate feedbacks, and develop
improved hydrometeorological parameterizations.
- Accelerate developments in models of the land, atmosphere, and entire climate system:o Continue evaluation of developing earth system model products.
o Develop archives to support model development and intercomparison.
- Attribute causes of trends, and determine the predictability of energy and water cycles on a global and regional basis incollaboration with the wider WCRP community.
o Coordinate data set generation, process studies, and modelling- Diagnose model errors and exploit GEWEX datasets and focused process studies.
3. Objectives(i) To develop dataset that will be directly usable for evaluation of climate model outputs, i.e. will cover various regions/climate
conditions over the world, will allow for deriving climatologically sensible mean diurnal cycles (sufficient length of observations),
and will be convenient for use (format, metadata, easy access, QC-ed).
(ii) Complement in-situ observations with satellite data to provide spatial coverage of observed variables consistent to the scale ofclimate models.
(iii) Use the dataset for quantification of uncertainties of CMIP5 climate model projections and producing usable information for
decision and policy makers.
(iv) To assure an easy access to the data for a wide community through a user-friendly on-line system – Date Integration andAnalysis System (DIAS), that provides a set of data analysis, integration and visualization tools, free of charge.
(v) Through a timely accomplishment of the above – to contribute to the IPCC AR5.
4. Merit-

real observational datacomprehensiveness of the dataset in terms of:o Spatial coverage – contributing sites will be nominated considering also their location with intention to cover as
many regions and climatic conditions as possible. 2D, 2.5D and 3D sites will be preferred (sites including morestations assuring spatial coverage of observations and also those containing PBL towers as well as soil
observations).
o Temporal coverage – sites covering the targeted 10-year period will be selectedo Variables – most advanced sites with complex observations will be preferredo Data sources – reference site data will be complemented with satellite observations for square areas of 250km x
250 km around the sites-

unified, standardized format
consistency in terms of observed parameters – also consistent with model outputs following NetCDF CF conventions
interoperability – standardized metadata
accessibility – DIAS

The targeted dataset has advantages over “reanalysis” datasets by providing (a) observational data and by (b) enabling a single
commodity that includes all data in a standardized format and (c) the gap that exists between observed parameters such as rainfall
versus reanalysis values for example.
5. End Users(i) CMIP5 project – climate model output evaluation
CMIP5 promotes a standard set of model simulations (Taylor et al., 2009) in order to:
1. evaluate how realistic the models are in simulating the recent past,

15

2.

provide projections of future climate change on two time scales, near term (out to about 2035) and long term (out to 2100
and beyond), and
3. understand some of the factors responsible for differences in model projections, including quantifying some key
feedbacks such as those involving clouds and the carbon cycle
Under the CMIP5 strategy there are two distinct foci of the model experiments: 1) near-term simulations (10- to 30-years) and 2)
long-term (century time-scale) simulations initialized from the end of freely evolving simulations of the historical period. In addition,
CMIP5 also admit so-called “time-slice” experiments that involve simulations with unusually high resolution atmospheric models ormodels with more complete treatments of atmospheric chemistry.
There are two core near-term CMIP5 experiments, one a set of 10 year hindcasts or predictions initialized from climate states inthe years 1960, 1965, 1970, and every five years to 2005, with this last simulation representing the sole actual prediction beyond
the present (i.e., beyond 2009). In these 10-year simulations, it will be possible to assess model skill in forecasting climate change
on time-scales when the initial climate state may exert some influence. The other core experiment extends the 10-year simulations
initialized in 1960, 1980, and 2005 by an additional 20 years. It is at this somewhat longer timescale that the external forcing fromincreasing GHGs should become more important. “Time-slice” experiments fall into the CMIP5 near-term “Tier 1” group of
experiments including both the present-day (AMIP period: 1979 - at least 2008) and the future (specifically, the decade 2026-2035)
simulations and offer opportunities to (for example) to:•
explore the implications of running climate models at high resolution,•
examine the regional effects of climate change at small scales where impacts are felt,•
study the air quality implications of climate change with models that include sophisticated treatments of atmosphericchemistry, and•obtain more robust statistics characterizing changes in climate, in particular the likelihood of rare or extreme events.
The temporal resolution of the model output is 3 hours and the spatial resolution is 60 km in almost all models participating in thenear-term experiments and as fine as 20 km in some models in the time-slice experiments.
The targeted 10-year dataset will be applicable for evaluation of the CMIP5 near-term and time-slice experiment simulations. The
10-year period dataset is sufficient to derive climatologically sensible mean diurnal cycles, it is also useable for analyzing intraseasonal variability or extreme events under the current climate. On the other hand, it is not sufficient for analyzing inter-seasonalvariability and evaluation of the CMIP5 long-term simulations.
It is proposed that evaluation and intercomparison studies are done in a collaborative manner between the modeling group(CMIP5) and relevant science groups who have experiences in carrying out similar studies in specific fields. For example, theLandFlux-EVAL group will focus on the evapotranspiration fluxes assessment, the GSWP groups will focus on soil moisture, etc.

6. Technical details
Data to be included- Data providers: FLUXNET, CEOP, GCOS, satellite data
- Number of sites to contribute – CEOP, FLUXNET groups will nominate the best candidates: FLUXNET “Golden sites”, CEOP
sites contributing since the beginning of CEOP Phase 1. Suitability of a site will be assessed based on its compliance withprioritized characteristics. The value/priority of consistency of data versus full decade availability, versus geographic distribution
versus other related characteristics is to be discussed and confirmed.
- Comprehensive dataset covering energy and water budgets is targeted that will be useable for multiple purposes and thus theproviders will be asked to provide as many parameters as possible. Basic requirements for CMIP5 are given in the CMIP5
simulation protocol (Taylor et al. 2008).
- Data period is to be discussed and decided. There are two views: (i) some reference sites may have difficulties toprovide/process most recent data and may prefer earlier period, e.g.: 1998 – 2007, while (ii) other reference sites data andsatellite data may not be available for that period yet (MODIS data from 2000).

1. INTRODUCTION
The 10 Year Dataset Project was initiated as an international effort in 2010 by the World Climate Research Programme (WCRP)
Observation and Assimilation Panel (WOAP) and the WCRP Global Energy and Water Cycle Experiment (GEWEX) and involves
several projects, initiatives, organizations and agencies who committed to provide their observation reference sites and/or satellite
data per agreed to rules defined in this Whitepaper above. 10-YDP satellite data providers also comply to the CEOS satellite dataexchange principles for research (http://monsoon.t.u-tokyo.ac.jp/ceop/policy1.html) and the CEOS data principles for operational
environmental data (http://monsoon.t.u-tokyo.ac.jp/ceop/policy2.html).
The time periods for which data will be archived will cover the (to be decided).
Archiving all 10-YDP data into one central archive, namely DIAS at the University of Tokyo, and creating harmonized data formats
is an essential element of the 10-YDP data policy in order to provide easy access to the data for the targeted communities. The
latter will be referred to as data users in the following data release guidelines.
10-YDP contributing reference sites have been established and are being maintained by a variety of institutions, organizations,
national services, international and national research groups, and research individuals. Henceforth, these and the national andinternational space agencies providing satellite data will be referred to as data providers. Maintaining continuous, high-quality
measurements, performing quality and error checking procedures, and submitting data and related documentation to DIAS
requires substantial financial and logistical efforts of the data providers. The necessary support for these activities originate from avariety of international, national and institutional sources.
2. 10-YDP DATA RELEASE AND DISSEMINATION GUIDELINES
2.1 Free and unrestricted Release of Data
The no-restriction principle shall in particular mean that no financial implications are involved for the 10-YDP data exchange. 10YDP data providers shall transfer their measured data to the DIAS free of charge. Also, 10-YDP data files established at the DIAS
shall be offered free of charge to 10-YDP data users.
2.2 No Commercial Use or Exploitation
It is understood that all 10-YDP data shall be delivered to data users only for research and scientific purposes compliant with theobjectives described in the 10-YDP Whitepaper. Commercial use and exploitation by neither the data users nor the DIAS is
prohibited, unless specific permission has been obtained from the data providers concerned in writing.
2.3 No Data Transfer to Third Parties
One restriction which will be imposed on all data users concerns the re-export or transfer of the original data (as received from the
DIAS archive) to a third party. Such restriction shall apply to all categories of 10-YDP data, and is in the best interests of both thedata providers and the potential users. Unrestricted copying of the original data by multiple, independent users may lead to errors
in the data and loss of identity of its data provider-DIAS origin and is strictly prohibited.

DIAS will offer 10-YDP data files to potential data users through electronic means, (e.g. the internet). The DIAS shall install
technical means to keep protocol on all data transfers to data users thus maintaining a catalogue of all data users, and the data
files they have obtained.
2.4 Acknowledgement and Citation
Whenever 10-YDP data distributed by DIAS are being used for publication of scientific results, the data's origin must be
acknowledged and referenced. A minimum requirement is to reference 10-YDP (or particular project/database (CEOP,FLUXNET/AsiaFlux…)?) and DIAS. If only data from one data provider/source/project? or a limited number of reference sites has
been used, additional acknowledgement to the data provider/source/project? or reference site(s) and its (their) maintaining
institutions or organizations shall be given.
Maintaining continuous, high-quality measurements, performing quality and error checking procedures, and submitting data andrelated documentation to the DIAS will require substantial financial and logistical efforts of the data providers. The necessary
support for these activities originate from a variety of international, national and institutional sources. The DIAS shall make proper
reference to all 10-YDP data providers and, if required, to their funding sources.
2.5 Co-operation between 10-YDP Data Users and Principal Investigators (PIs) at the 10-YDP Data Providers
Data users of 10-YDP data are encouraged to establish direct contact with PIs at data providers for the purpose of complete
interpretation and analysis of data for publication purposes.
2.6 Co-Authorship for 10-YDP Principal Investigators (PIs)
Co-authorship of 10-YDP PIs on papers making extensive use of 10-YDP data is justifiable and highly recommended, in particular,
if a PI has responded to questions raised about the data's quality and/or suitability for the specific study in question, or has been
involved in directly contributing to the paper in other ways. It is highly recommended that any data user should contact the
responsible PI and ask him/her if he/she wants to become co-author, or if an acknowledgement (see section 2.4) would be
sufficient. If co-authorship is requested, the PI and the data user should establish a basis for collaboration. A PI in this context
means the responsible site or instrument scientist or any person (student, collaborator) that he/she may suggest.
2.7 CEOP Publication Library
Whenever 10-YDP data distributed by DIAS are being used for publication of scientific results, the author(s) shall sent a copy of
the respective publication, preferably in electronic form, to the DIAS (or 10-YDP point of contact?) in order to build up a 10-YDP
publication library. DIAS (or 10-YDP?) will maintain this library and will make it public, for example via DIAS (or 10-YDP?) web site,
for a continuous monitoring of the 10-YDP data applications and 10-YDP's achievements in general.
