SUBJECT: Minutes of FIRE Arctic Cloud Working Group Meeting

On January 29-30, 1997, the FIRE Arctic Cloud Science Team (FST) met in
Boulder, Colorado, to complete final planning for the upcoming FIRE
Arctic Cloud Experiment. On January 28, the Data Management Working
Group (DMWG) also met. Enclosed are the agendas and lists of
participants for both meetings.

Curran presented an update on NASA and announced that Mission to Planet
Earth has been renamed as the Office of Earth Science. He stated that
FIRE was very fortunate to receive a substantial budget increase in FY98
so that the Arctic Cloud Experiment can be conducted as planned and on
schedule.

Cress gave an update on ARM and announced that Christmas Island will be
thoroughly instrumented, like the other two tropical western ARM sites
at Manus and Nauru. The PSU Raman lidar will operate at Barrow in early
spring and may operate during FIRE Arctic Phase I if additional funds
can be acquired.

Zak reported on the status of ARM instruments at both SHEBA and Barrow.
To a very high degree, the instruments are all fully operational. Data
transfer from SHEBA occurs in 6-week intervals.

Moritz gave an update on SHEBA. The ice station has been operational
since November. Some new ice leads have recently appeared fairly close
to the ship and surrounding campsites. Data from SHEBA will be available
to researchers with some time delays. For example, weather observations
are available 2.5 hours afterwards; sonde, PAMS, and radar data is
delayed 1\~2 days. SHEBA is concerned that the ship may drift further
westward and approach Russian territory at 169˚W. If so, FIRE's aircraft
may have to initiate diplomatic clearances for operations in Russian
airspace. \[SHEBA has produced trajectories for each of the last 20
years. They are available on its website.\] The SHEBA data archive will
remain at UCAR for the next several years but will eventually be
transferred to NSIDC, Boulder.

Curry stated that SHEBA is considering establishing the period of May
4-28 as the second SHEBA Intercomparison Period (IOP-2). This would
dovetail nicely with the FIRE aircraft operations, especially the C-130.
SHEBA management is in favor of having joint SHEBA/FIRE science team
meetings from now on. She will make this a topic at the next SHEBA
Science Team meeting, March 4-6.

Wylie described the weather forecasting plans and components. He noted
that the in situ aircraft may be concerned about icing, since water is
present in the clouds about 30% of the time of our operational periods.
He will forecast for the areas surrounding the SHEBA ice station,
Barrow, Inuvik, and Fairbanks. From April 7-28, he will forecast from
the University of Wisconsin; from April 29-June 13 from Fairbanks; and
July 5-30 from Fairbanks. He will set up in the meeting room in hangar
4, Fort Wainwright, with forays to NWS for key information and Alaska
basin forecasts. Unfortunately, NWS has no electronic export from their
office.

Uttal will send in a daily surface instrument report, to arrive around
0900 ADT. She foresees communications to and from the ship involving, in
order of preference: a. email (downloaded from SHEBA daily in the
morning and forwarded by APL by 0900 ADT); b. fax; c. telephone (these

2

three methods all require linking with geostationary satellites
(INMARSAT charges \~ \$8/min; IMSAT charges \~ \$2/min); and d. HF radio
link (either through the Canadian Coast Guard at Inuvik or directly with
Fairbanks, if both sites have access to a HF radio. Uttal has requested
the use of the SHEBA HF radio.) Moore stated that there has been good
communications with INMARSAT when the ship was at 76˚N; he expects that
this will hold even up to 80˚N. There is a commercial email service at
Barrow for \$40/month.

The discussion on aircraft operations focused on the schedule of
operations. Based on aircraft takeoffs at 1100, the daily schedule of
operations is given in table 1. Other topics addressed were that the
University of Washington (UW) C-580 will extend its operations to June
13. Forecasting will continue to be provide by Wylie; the experiment web
page will continue to be updated by Olson. The ER-2 requires that the
SHEBA helicopter be available and on standby in case of an ER-2 downing.
Thus, the ER-2 will not fly farther than 150 km from the ship (and
helicopter). The C-130 will not fly 2 days in a row; the ER-2 and UW
may. UW can do multiple flights over Barrow, i.e., several 2-hour
flights. It will also have about 4 hours on station at SHEBA. Sample
flight patterns were presented for the ER-2, C-130, and UW including a
bow tie, thin bow tie, mapping with both 60 and 20 km legs, and
L-patterns for turbulence. If the C-130 flies over or very close to
Barrow on its way to SHEBA, it should turn on its instruments after it
crosses over the Brooks Range.

During the Operations Plan overview, it was noted that sections dealing
with post-experiment analysis plans will be deleted (section 8). A new
Data Analysis Plan will be developed by Rossow and Bretherton. The rough
draft will be available about 1 month before, and will be the focus of,
the next meeting, the Science Data Workshop-I.

Separate working groups focusing on the ER-2, C-130, UW/AES/surface, and
satellite operations were held. King reported on the ER-2 meeting and
announced that the instrument configuration is

3

set: MAS, CLS, MIR, SSFR, AMPR, AirMISR, and SHIS. The NASA 709 will be
used. The pilots will be Barrilleaux and Nystrom. NASA 709 is scheduled
for maintenance February 15 - April 1. AVIRIS will fly some local
flights in mid-April. FIRE instrument integration will begin May 4.
There will be a test flight on May 11. Reynolds noted that foreign
nationals are an issue at Dryden Flight Research Center (DFRC), since
the aircraft operations are on the Air Force side. NASA will sign off on
foreign nationals, but they are required to be escorted at all times by
the responsible PI.

Based on 60 flight hours, there are but 46.6 science hours available
after the transit and test flights are subtracted. This results in about
7-8 flights of \~6 hours duration, or about a flight every 3 days.
Additional flight hours might become available if: a. the ER-2 conducts
special flights for the National Park Service from June 8-22, which
frees up 5.5 hours of return transit flight time; and b. AMSR would like
to extend the flight legs further northward (subject to the 150 km
radius constraint). If so, EOS might support additional hours. The ER-2
flight patterns will be rasters (with 280 km legs), crosses (with 280 km
legs), Landsat coordination (May 21 and June 6), AVHRR calibration
(clear skies), and UW overflights (BDRF measurements). The ER-2 cannot
fly lower than 52,000 ft. over SHEBA; it can fly lower over Barrow. All
ER-2 instruments will have data quick-look capability and will have a
scientist on-site.

Curry reported on the C-130 operations. The flight patterns will be L's
or boxes over SHEBA and spirals downwind of SHEBA. Coordination is not
needed with the AES or ER-2 aircraft. There is a low but finite
probability that the C-130 may be able to conduct limited operations
over the ARM site at Barrow. It will have a built-in time slot for
target-of-opportunity observations; Barrow would be one candidate to
consider.

No report was given for the AES/UW/surface group, but there is good
agreement as to what each is planning to do.

Minnis reported on the satellite operations. He will produce, in
near-real time at Wainwright, loops of images of a variety of
satellite-inferred data parameters for locations over SHEBA, Barrow, and
Fairbanks. GIF images will be available at Fairbanks; digital data will
be available at Langley.

McDougal reported on the progress of the Data Management Working Group
that met on January 28. The DMWG has grouped the data parameters
according to their measurement similarity: surface-based passive remote
sensing, surface-based active remote sensing, aircraft remote sensing,
aircraft in situ sensing, satellite remote sensing, and modeling output.
The data parameters were reviewed for completeness and utility. A data
category number was tentatively assigned to each data parameter that
reflects the data usefulness to researchers and time schedule for
archiving. Two new data categories were added: category 0 for quick-look
data that will not be archived; and category 4 for high risk, low degree
of success, but ambitious undertaking to produce new data products.
These will also not be archived unless the development is successful;
then it will be upgraded to category 3. See table 2. The data management
schedule that is listed in the Operations Plan was reviewed with no
changes.

Each of the data parameter gurus reported on the list of data parameters
and data category numbers in their sections. These reports were accepted
by the Science Team without modification. The lists will be incorporated
into the Operations Plan.

Bretherton recommended that FIRE adopt SHEBA's common data format, which
was developed for point source and aircraft observations. This format
will greatly ease the development of the

4

Integrated Data Sets from multiple sources. The use of the FIRE Data
Format will be recommended to be used for data submittal, but not
required. The recommendation was accepted.

Gerber reported on the Microphysical Quality Assurance activity. His
recommendation that ALL instruments, not just the microphysical
instruments, incorporate the documentation described in the
Microphysical Quality Assurance section in the Operations Plan was
accepted. This documentation should also be submitted as part of each
instruments data submittal. The QA program will include: a. complete
documentation; b. use the PVM, which will be on all three in situ
planes, as a reference for the other microphysical probes; c. NCAR
initiate a National Calibration Facility (not likely), and Sensor
Calibration Units, to be designed and developed by Droplet Measurement
Technologies, to be installed on all three planes.

Rossow reported on the Radiation Calibration activity. To date, the
radiation instrumenters are following the guidelines listed in the
Operations Plan. He concurred with the documentation recommendations,
added that calibration results should also be included in the data
submittals, and recommended that an "estimate of error" also be included
as part of the data submittals. These recommendations were accepted.

Olson, FIRE Archive Data Manager, will install a local area network
(LAN) at hangar 4 and arrange for it to be hooked up, via a T1 line, to
the internet. This will allow on-site communications between
participants, off-site exchange of information, and non-participants to
be kept abreast of the experiment operations and highlights. He will
also operate the experiment web page from LaRC April 7-28, from
Fairbanks April 29 - June 7, from LaRC June 8-13, and from Fairbanks
July 5-30.

For the Integration Task Team efforts, Wielicki reported on Satellite
Remote Sensing. He emphasized that the experiment strategy will be to:

a)  use the aircraft in situ measurements to validate the surface-based
    uplooking remote sensing profiles;\
    5

b)  use the (validated) surface-based uplooking remote sensing to
    validate the downlooking satellite remote sensing profiles; and

c)  use the (validated) satellite sensing to validate the global models.

He noted that many of the ER-2 instruments have direct links to EOS
instruments. The ER-2/EOS instrument linkages are: MAS/MODIS,
AirMISR/MISR, AMPR/AMSR, CLS/GLAS, SSFR/CERES, and SHIS/AIRS (plus
AVHRR, HIRS, and SSMI). Table 3 lists the key data sets that must be
acquired, with a minimum of 10 cases. Spirals are good for microphysics;
stair steps are good for radiation and turbulence.

Krueger reported on Surface Remote Sensing. The surface-based
measurements will include vertical cloud profiles, surface radiative
fluxes, sonde profiles, surface spectral albedo, and BDRF. He will look
at the issue of spirals versus stair steps as the best in situ flight
pattern to validate the cloud radar and lidar measurements.

Bretherton, in the Modeling report, emphasized that one of the key
issues is to understand the effects of ice, mixed phase, and water
particles on the cloud microphysics and radiation. The experiment is
time-phased to do just that.

During the experiment, there will be several reviews:

All subsequent Arctic Cloud Working Group meetings will be coordinated
with SHEBA Science Team meetings. The next FIRE meeting was discussed to
be dovetailed with either the Fall AGU, San Francisco, December, or 1999
AMS, TBD, January. Discussions with SHEBA will be forthcoming.

There will be a BAMS post-experiment article headed up by Curry and
Randall. They will lay out the framework for the key sections and
instrument components. Inputs from the individuals will be completed by
the end of the experiment.

The issue of non eye-safe lidars from aircraft and surface instruments
to surface and aircraft personnel's perspective was addressed. All
lidars will send their safety documentation to the Project Office for
distribution to possibly affected entities, such as the ER-2 office.

All press releases will be coordinated with AES, SHEBA, ARM, and
Wainwright.

Jim Raper led an informal set of discussions to consider issues that
were of a one-on-one nature for inclusion in the Operations Plan. Final
modifications were to be given to Jim before the end of the meeting.

The following action items were identified:

[Project Office]{.underline}

1.  Ensure that the LAN/T1 line will be open for the period June 8-13
    for Wylie to provide forecasting support for the UW extended
    operations \[completed\].

2.  Include Uttal's form into the Operations Plan \[completed\].

3.  Inquire to Iridium to see if they can provide free communications to
    and from the SHEBA ice station.

4.  Inquire to Wainwright about: a. the need for and time of possible
    repairs to the taxiways in case they are damaged during the winter
    \[we will wait until spring; moneys have been reserved for
    this\]; b. keeping the control tower and weather office open on
    weekends to support FIRE aircraft operations \[there will be
    overtime costs; moneys have been reserved\]; and c. need for list of
    foreign nationals. \[Wainwright has reiterated that it is an open
    base, but that foreign nationals will be limited to the those
    locations where the experiment will be conducted\].

5.  Inquire to GSA about possible vehicles available for FIRE.

6.  Contact Moritz about who will be responsible for launching the
    additional 2/day sondes at SHEBA during the FIRE experiment phases.
    \[Moritz stated that SHEBA will be responsible, taking advantage of
    manpower from NOAA and himself; part of the moneys that FIRE will be
    providing to NSF will be used for this\].

7.  Include list of data parameters in Operations Plan \[completed\].

8.  Coordinate all press releases with SHEBA, ARM, AES, and Wainwright.

9.  With [Curry]{.underline}, coordinate next and all subsequent Arctic
    Cloud meetings with SHEBA. Possible options are the November
    -December period (about 6 months after IOP-2), December as part of
    the Fall AGU, and January as part of a special session of AMS \[to
    be addressed at SHEBA Science Team Meeting, March 4-6\].

10. Consolidate all lidar safety plans (for eye-safe operations) and
    forward to possibly impacted entities (ER-2, \...).

11. Try to get moneys to NCAR or Droplet Measurement Technologies for
    the construction of three Sensor Validation Units \[in process\].

12. With [Zak]{.underline}, draft FIRE/ARM Memorandum of Agreement
    (MOA), focusing on existing FIRE/SHEBA and ARM/SHEBA MOAs to close
    the loop.

[Olson]{.underline} will operate the Arctic Cloud Experiment web page
during the two phases from Fairbanks, except from LaRC during April 7-28
and June 8-13 \[agreed\].

[Curran]{.underline}

1.  Begin diplomatic clearance efforts for permission to operate the
    NASA ER-2 and UW C-580 aircraft in Russian airspace, due to the low,
    but finite, possibility that the SHEBA ice station may drift close
    to Russian territory at 169˚W. NCAR is pursuing this also, so the
    C-130 plans will be included for completeness.

2.  Make decision on participation of SHIS \[concurred\].

[Moritz]{.underline} will provide ship drift location and trajectory
forecasts to Project Office and Curran. \[The SHEBA trajectories have
been calculated based on the last 20 years of meteorological data. The
results show that the ship may indeed drift close to Russian territory
about one third of the time. The trajectories are now posted on the
SHEBA experiment homepage\].

[Comiso]{.underline} to provide SSMI sea ice products for the period
April 1 - June 30 to LaRC DAAC.

[King]{.underline} to explore additional ER-2 flight hours based on
AMSR's needs.

[Reynolds]{.underline} will review suitability of ER-2 flights directly
over ARM site at Barrow, based on possible non eye-safe Raman lidar
operations.

[All lidar operators]{.underline} to provide their safety plans to the
Project Office, who will consolidate them and forward them to possibly
impacted entities (ER2, \...).

[Rossow and Bretherton]{.underline} to draft Data Analysis Plan
outlining the post-mission analysis plans for FIRE. The draft is to be
available 1 month before, and will be the focus of, the next FIRE
meeting.

[Individuals]{.underline} who plan to have ethernet hookups to the
experiment LAN at Wainwright should forward the LAN information form to
the Project Office.

[Krueger]{.underline} to look at the results of spirals versus stair
steps for in situ aircraft flight patterns that were performed in the
SHEBA IOP-1 for the validation of surface-based sensors.

[Curry and Randall]{.underline} to develop the framework for a
post-mission article to BAMS. Various inputs from [key
investigators]{.underline} should be provided to them by the end of the
experiment.

In summary, the science team felt that preparations for the Arctic Cloud
experiment were well in hand, and they were eager and anxious to begin.
