Report of WOAP-IID. Stammer

• Session 1  WOAP , where are we, where do we go ?
• Report on WCRP JSC and place of WOAP within WCRP
• Observations and their analysis in WCRP/COPES (K.
  Trenberth)
• WMP to WOAP-II (J. Shukla)
• WOAP might get supported through WCRP and GCOS
  but would need then to change its TOR (see
  below).
• Task groups were formed on the following
  subjects
• 1) Reanalysies (A. Simmon, D. Stammer, G. Flato,
  J. Shokla)
• 2) Data management T. Koike, E. Harrison, M.
  Tjernstroem, Mac Farlane
• 3) Reprocessing R. Lawford, J.L. Fellous, A.
  Lorence
• 4) GEO Items G. Sommeria, M. Manton, T. Koilke,
  M. Rast, R.J. Du Cachat

WOAP-II

• Session 2 Coordination with GCOS
• GCOS update for WOAP (D. Goodrich)
• OOPC to WOAP-II (DE Harrison)
• Summary of AOPC annual meeting ongoing
  activities (A. Simmons)
• WOAP expressed its support for a formal
  confirmation of a joint sponsorship of TOPC by
  WCRP.

WOAP-II

• Session 3 Space matters and relation with
  space agencies
• 3-1 GCOS satellite observation supplement
• 3-2 CEOS response to GCOS IP (JL Fellous)
• ASIC (Achieving Satellite Instrument Calibration
  for CC)
• 3-3 NPOESS status (A. Heidinger and J. Key)
• CEOS response to GCOS IP is an important
  initiative which may impact future GCOS and WOAP
  activities. The GCOS IP supplement was discussed
  stressing that space requirements for climate
  were well defined in the past. But need for
  priorities
• 1) Continuity
• 2) Reprocessing and reanalysis of past data
• 3) Multiple ECVs, land, ocean, atmosphere
• 4) Calibration, accuracy, benchmark, in situ
• 5) Climate variable need to have higher priority,
  especially with NPOESS cuts.

WOAP-II

• Session 4 Participation in GEO and IGOS-P
• 4-1 GEO update (M. Rast)
• WCRP-GEO (G. Duchossois G. Sommeria)
• 4-3 IGOS water theme (R. Lawford)
• 4-4 IGOS cryosphere theme (J. Key)
• Recommendations a task group led by G. Sommeria
  will propose to the panel a message on GEO which
  will support a joint input by WCRP and GCOS to
  the 2007-2009 work plan. It will stress the need
  to use the GCOS IP and follow-on satellite
  supplement as the main guideline for climate
  tasks and include a message on funding for
  climate activities.

• Session 5 Data activities
• 5 -1 CEOP (T. Koike)
• 5-2 WMO Information System (JM Rainer G.
  Sommeria)
• 5-3 Data management activities (T. Koike)
• Recommendations WMO WIS should be publicised
  within the WCRP community and should be
  considered by all projects.
• Matrix on data management (policy, meta data, web
  site), prepared by Koike needs to be validated
  and completed. One issue is the general data
  management within WCRP. All existing efforts were
  developed independently, but this needs to be
  homogenized to ensure synergies.

6

• A task group chaired by N. Mc Farlane will review
  the status and management of observational data
  and model output archives, including web sites
  within WCRP, and will make recommendations for
  WCRP-wide overarching structure, site contents
  and data policy (see issues above). It will be
  composed of one member from each of the
  core-projects GCOS, WMP. Time line
  membership 31 Dec 2006 Final report 31 July
  2008).
• Members
• Chair (initially) Norm McFarlane
• SPARC Bill Randel
• CLIVAR ???????????????
• GEWEX
• CLiC
• CEOP
• WMP Jim Kinter
• WCRP Gilles Sommeria, Catherine Michaud

7

• Proposed terms of reference.
• The task force will review the status and
  management of observational data and model
  output archives within the WCRP core projects to
  ascertain
• The current status of archived data and model
  output (what? where? purpose?).
• The degree of accessibility and ease of access to
  archived material.
• The degree of redundancy in the archived material
  either within the WCRP or between WCRP and other
  archives (e.g. major data centers).
• Anticipated future archiving of observational
  data/model output
• Possible need for and ways to facilitate
  coordination of data archiving and management in
  the WCRP
• Possible future resources needed for data
  archiving and management
• The task force will report to WOAP and make
  recommendations as to possible actions that may
  be taken.

8

• Session 6 Reanalyses
• 6-1 Report from Maryland workshop Observations
  requirements for future reanalyses (S. Uppala)
  Recommandations (K.Trenberth)
• 6-2 Report from ECMWF workshop (A Simmons)
• 6-3 GSOP report (D. Stammer)
• 6-4 Reanalysis conference (T. Koike)
• 6-6 WGNE activities (A. Lorenc)
• Recommendations
• A. Simmon and K. Trenberth to write EOS article
  about atmospheric reanalysis workshop to publize
  benefits and importance of reanalysis for climate
  research.
• WOAP endorses plan for 3rd International
  Reanalysis Conference and recommends support by
  WCRP and GCOS as well as GEO.
• Next WOAP meeting will address coupled
  atmosphere, ocean, sea-ice and land data
  assimilation issues (in support of seamless
  prediction).
• A working group, led by WCRP and GCOS will
  address issue of development of improved
  observational data sets for reanalysis.

WOAP-II

• Session 7 Reprocessing
• Need for reprocessing is an important element of
  the CEOS response to the GCOS IP and follow up
  activities. The need for reprocessing shhoul dbe
  featured as part of the letter to CEOS.
• Session 8 Reflection on WCRP observation
  strategy
• 8-2 GCOS/NOAA meeting on reference RS network
  (D. Goodrich)

WOAP News

• At OCD Meeting in Beijing, Ann H-S announced that
  WMP and WOAP would no longer be supported and
  that there is no further money to meet again.
• There is no money for Kevin to attend next JSC
  meeting.
• 200K (all COPES money) have been spent on network
  survey, creating a budget crisis within WCRP.

CLIVAR GLOBAL DATASETS AND REPROCESSING ACTIVITIES

• CLIVAR is currently seeking to build and utilise
  reference datasets for climate research as part
  of its Global Synthesis Evaluation Framework
  activity led by the CLIVAR Global Synthesis and
  Observations Panel (GSOP), in association with
  GODAE.
• CLIVARs global ocean synthesis effort is
  focussed around the concept and goal of ocean
  reanalysis products that synthesize all
  available ocean satellite and in situ
  observations by merging them with ocean models
  using assimilation techniques.
• Ocean reference datasets and their error fields
  are required as input for the synthesis efforts,
  but also to help evaluate the skill, usefulness
  and limitations of various synthesis and modeling
  approaches.
• White paper on CLIVAR/GODAE Global Synthesis
  Evaluation Framework gives background on need and
  role of reference datasets within CLIVAR.
• While GSOP efforts are focussing at this point on
  the ocean synthesis, the next urgent step will be
  to move toward coupled climate-quality synthesis
  as well as the initialisation of coupled forecast
  models using ocean and coupled synthesis
  products.
• Beyond CLIVAR's own needs, climate reference
  datasets are also required to meet wider needs
  for climate information. In particular the GCOS
  IP (section 3.5) identifies the need for analysed
  products for all Essential Climate Variables
  (ECVs).
