2. Applied Science and Research IICWG IV Action Items SC4.1: Distribute information on the NASA Data Assimilation Workshop for sea ice at Woods Hole Oceanographic Institution to other members of science committee. Responsible: M. Van Woert. Status: CLOSED Short Course on Data Assimilation for Sea-Ice Modelers took place May 10-11, 2003 at Woods Hole Oceanographic Institute.

3. Applied Science and Research IICWG IV Action Items SC4.2: Report to ASRC and IICWG-V on NASA Data Assimilation Workshop. Responsible: M. Van Woert. Status: CLOSED The lecture material is available at: http://ecco.jpl.nasa.gov/sea_ice. Reference text is “The Ocean Circulation Inverse Problem” by Carl Wunsch.

4. Applied Science and Research IICWG IV Action Items SC4.3: IICWG recommends converting sea ice model output in a common data format, netCDF, in order to better share/exchange data. Responsible: Members of Science Committee. Status: OPEN met.no/DMI: The OSI SAF sea ice products will be available in netCDF. This is a part of the EU FP-6 project MERSEA. In MERSEA it will be organized as a common met-ocean data distribution server for exchange of data. This will also include sea ice model output from met.no/MERSEA site. CIS: CIS Modeling Lab has the capability to generate netCDF format output. Transition to this as standard format will occur over the next year as coordination is required to integrate and be compatible with the Canadian Meteorological Centre

5. Applied Science and Research IICWG IV Action Items SC4.4: Investigate the possibility of direct assimilation of passive microwave radiance, scatterometer backscatter, infrared radiances, and visible reflectance. Responsible: Members of Science Committee. Status: OPEN – ONGOING To be discussed at IICWG-5 Science Workshop. To be addressed as part of DA activities.

6. Applied Science and Research IICWG IV Action Items SC4.5: Identify national science leads at each ice center in order to develop a structure for collaboration. Responsible: IICWG National representatives. Status: OPEN - ONGOING * U.S.: Mike Van Woert * Norway: Lars-Anders Breivik * Canada: Tom Carrieres * Denmark: Rashpal Gill * Russia: Sergey Klyachkin Other national leads TBD.

7. Applied Science and Research IICWG IV Action Items SC4.6: Focus of next science workshop will continue to emphasize modelling & DA, advanced tutorials on model, satellite algorithms, and data assimilation. Model performance info incorporating guidance from CJRS paper. Responsible: Science Committee Co-Chairs. Status: CLOSED IICWG-5 Science Workshop agenda addressed most of these items. Further discussion and action to be undertaken during IICWG-5 committee sessions.

8. Applied Science and Research IICWG IV Action Items SC4.7: Recommend that national model leads attend next workshop and present latest results. Responsible: IICWG members. Status: CLOSED Canada, US, and Norway leads presented. New presentations from centres and institutes in Germany, Norway, and UK.

9. Applied Science and Research IICWG IV Action Items SC4.8: Finalize and publish the "White Paper on Data Assimilation," under an official publication. Responsible: T. Carrieres, L-A. Breivik. Status: OPEN Appropriate target publication and/or agency has not been identified. Input still required (see SC4.9) and paper requires further work. To be addressed during IICWG-5 committee sessions.

10. Applied Science and Research IICWG IV Action Items SC4.9: Provide national input data, model and data assimilation inventory, national input to modeling system requirements and further comments to ASRC and JCOMM ETSI chair by June 30, 2003. Responsible: IICWG members and specific information from Baltic Sea Ice Services WG. Status: OPEN Incomplete. To be addressed during IICWG-5 committee sessions.
