MODEL OUTPUT DATA GROUP GENERAL ISSUES
3.1 Opening and WCRP and GEWEX related issues
(3.1a) Benedict welcomed everyone on the call and appreciated the work that the CEOP Model Output
group 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 the climate
modeling community need of a high quality observation data of a sufficient length for evaluation of
climate 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 compliant with the CEOP
commitment taken at the 3rd 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), is envisioned 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.
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 it was agreed that a
Whitepaper would have been developed and submitted for discussion at the Pan-GEWEX meeting in
August.
(3.1c) Benedict reiterated that the 2nd 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 to accomplish 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, and GMPP)
will have one and a half day (Tuesday 24th and Wednesday 25th morning) of separate sessions dedicated to
its own issues. A CEOP evening session on Thursday 26th August has been added on the CEOP request. In
addition, a half day for panel interaction is scheduled on Wednesday 25th afternoon. Further information
including logistics details can be found at the meeting website.
It was also noted that considering the outcomes the individual GEWEX Panels including CEOP are
expected to deliver at the Pan-GEWEX meeting, the available time might 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 not fully substitute the 4 th CEOP Annual Meeting event and
that would be considered to take place early in 2011.
(3.1d) The group was advised that the next edition of the Special CEOP Issue of GEWEX News would be
published in August/September that would include scientific articles on energy budget modeling in dryland
areas and on linkages between the Asian Summer Monsoon and the Mediterranean region, an article on
the Extremes, updates on DIAS as well as recent CEOS activities, and other information.
3.2 JAXA CEOS/WGISS Test Facilities (WTF) for CEOP
(3.2a) Kudo reiterated that, the system had continued to run smoothly at: http://ceop.restec.or.jp/ and 150
users were registered. He reiterated that due to a technical issue at MPI/DKRZ, most of the MOLTS data
from the CEOP Phase 1 period that had been included on the system were not available anymore. These
data, however, is still available in the native format via ftp download from the MPI/DKRZ archive.
(3.2b) Kudo further reported that the development for the system expansion had advanced and
introduced the concept of the JAXA expanded “Water Portal” (this name is to be discussed and confirmed)
under CEOS that is based on the WTF-CEOP prototype. Participants were provided with the reference
slides prior to the call summarizing the plans for the system expansion as well as noting specific questions
on possible features of the system search functions and user interface (See Attachments 1, 2, 3). These
slides were referred during the call and the participants were asked to provide answers/suggestions from
their point of view as users. However, certain questions required more detailed discussion and thus it was
suggested that a separate focused call be held in the near future to address the questions on preferable
features of the interface and data search functions. Also, the participants were asked to provide their
answers/suggestions to Kudo in written form prior to that special call.
(3.2c) Consequently, several persons including Kato-Beaudoing, Ek, Rockel, and Toussaint answered
the questions in writing prior to this special call that was held on 27 July 2010. These prior inputs helped to
form the basis for the discussion and were greatly appreciated. Several points were addressed at the
special call however, certain issues remained that cannot be resolved at a conference call and should be
discussed at a focused face-to-face meeting between the JAXA/RESTEC team and a small “user team”,
which – as it was agreed – would be represented by UT experts from Prof. Koike’s group. Koike has action
(A2) to contact Miura and Kudo from the JAXA/RESTEC team and arrange such a meeting soon. The
results and possible ensuing actions for other members on the CEOP Modeling group will be communicated
by via email in due course.
3.3 MPI/DKRZ Current Status
(3.3a) Wegner reported that development of new server software was underway and should be completed
by the end of July. Testing will then be finished by mid-August and then the new system will be in full
operation.
(3.3b) Wegner further reiterated that due to a technical issue, certain MOLTS data had accidentally been
lost from the Oracle database where the data were accessible for the WTF CEOP system. Since reinserting these data back to the database would require significant amount of manual work, the MPI team
has decided NOT to perform this but rather to focus on the CEOP Phase 2 data that are now being
submitted in the agreed to CF compliant NetCDF format and that will be accessible for the WTF CEOP
system via an OPeNDAP server.
Consequently, Toussaint advised the group that installation of the TDS/OPeNDAP server and
Phase 2 MOLTS input had been completed. The available data (JMA 2007 to 2009-05 and ECMWF 200801) are available at: http://mesocyclone.dkrz.de:7070/thredds/catalog/ceop2/catalog.html. Also the
normalized lists for the OPeNDAP access keywords in the text format can be downloaded by the http
server. Presently, some jobs are running to nomalize the file names following last years agreements as
specified in the README file there. It is still necessary to layout and configure the TDS in a performing way.
3.4 CEOP Model Output format issues
(3.4a) It was reiterated that the Unified table of the MOLTS variables had been completed by B. Rockel
based on the responses from 5 Centers including NCEP, JMA, GLDAS, EMC, and ECMWF. The updated
table is copied below in Attachment 4. The analysis has shown that 130 quantities out of the 240 on the
original list are being provided by at least one of the centers and thus the list was trimmed to include these
130 variables. Also naming convention for CMIP5 has been included in the table in order to show the
relation between the individual Centers and CMIP5 output.
Katz voiced that NCEP would provide an updated list of variables and that would be incorporated
into the table. Williams mentioned that they had completed the conversion software to re-format the
Reference Site data to NetCDF and compared the parameters and units between the Reference Site and
Model Output version of the NetCDF files (CF convention). Most of the parameters have matched and thus
the Reference Site data team will proceed with the conversion of available Reference Site data to the
NetCDF format.
(3.4b) In addition, it was stressed out again that it would be highly desirable to update model output
documentation. The center representatives were asked to review the documentation currently in the
database associated with their Center’s data and update it as soon as practical (action A3).
(3.4c) It was mentioned that regarding the recent involvement of new Reference Sites, it would be useful
to update the list of MOLTS points. Koudelova has action A4 to update the list accordingly in cooperation
with Williams.
3.5 CEOP Global Model Study (http://gmao.gsfc.nasa.gov/research/modeling/validation/ceop.php)
Bosilovich reiterated that the MAC 2.0 version of the dataset had been added to their ftp site
(ftp://agdisc.gsfc.nasa.gov/private/ceop/). It includes ERA Interim, GMAO MERRA and JMA reanalyses
data and in addition to the previous version, it provides daily and monthly basin averages including MDB
and La Plata basins. This is considered final product of the MAC project. If anybody has a question related
to the MAC datasets, they should contact Dr. David Mocko (David.Mocko@nasa.gov).

CURRENT STATUS OF NWPCs
4.1 GLDAS by Hiroko Kato
Kato reiterated that their team was working on new version of the GLDAS datasets that was
generated using the Princeton forcing data and employing the CATCHMENT model resolving the land water
processes. When the new version is finished it will replace the current GLDAS product.
4.2 BoM by Lawrie Rikus
Rikus reported that their new modeling system was running in operational mode on new computers
and possible contribution to CEOP is being discussed. Rikus will advise the group of further progress on the
next call.
4.3 GMAO by Mike Bosilovich
Bosilovich reiterated that the 30 years of the GMAO MERRA reanalysis had been completed and
was available on-line through the NASA GES DISC server: http://disc.sci.gsfc.nasa.gov/mdisc/overview/.
He pointed out that they strongly recommend people to use this their sever for downloading the data, as
they are patching certain data files, so that will always have the latest and most up to date version. It may
be possible that copies of the MERRA datasets has been made by certain data centers but these copies
are NOT official MERRA and may not reflect the latest updates.
4.4 NCEP by Sid Katz
Katz reported that the NCEP team was implementing a major model upgrade including finer spatial
resolution. He also noted that they were anticipating approval from the MPI team on a MOLTS NetCDF
format sample file sent earlier. When the format is approved, they will begin to send the data routinely.
4.5 ECMWF by Tomas Kral
Kral reported that the format conversion software had been completed and tested a sample file of
data (January 2008) had been sent to MPI. When the format is confirmed by Toussaint, they will begin to
send the data routinely. He further reiterated that an issue was found in the model output, namely the
multilevel flux fields, that was most probably caused by a bug in the model. Further information on the
investigation results can be obtained by communicating with T. Kral (tomas.kral@ecmwf.int).
Kral also reiterated that the team was working on an upgrade of their forecasting modeling system
that included higher spatial as well as vertical resolution.
4.6 JMA by Toshio Koike
Koike mentioned that JMA was submitting their output regularly, in the format required by CEOP.
Nevertheless, JMA has been encountering a problem with the MPI interface when sending data, it seems
restricted and slows down the upload process. JMA representatives are communicating this issue with the
MPI team.
4.7 EMC by Alessandro Perotto
Perotto reported in writing that their new global model was finally set up and running daily on the
new computers. Perotto will start creating MOLTS and gridded data for CEOP soon and supposes to have
data prepared for upload by the time of the next call.
