4. Membership

5. Last CWG Meeting:March 29-30, 2005 Agenda Items • Climate Program Update - Koblinsky • Climate of the 20th and 21st century - Leetmaa • CLIVAR Update - Weller • Upper Air Observing Systems - Murray • NOAA Arctic Issues FY08-12 - Walsh • Climate impacts on Fisheries - Cyr • Planning for Climate Data Records - Karl • Community Re-analysis Project - Karl • Executive Session Note: Mark Abbott chaired this meeting

6. Meeting notes Intergovernmental Panel on Climate Change (IPCC) • NOAA IPCC modeling contribution focus is at the Geophysical Fluid Dynamics Lab (GFDL) • IPCC modeling requires a national strategy that distributes responsibility to all relevant performers Climate Variability and Predictability (CLIVAR) • What is US program’s relationship w/ Int’l CLIVAR? • GEWEX / CLIVAR linkages and NOAA role(s) should be articulated • Key roles for Climate Process Teams in CLIVAR activities Upper Air Observing Systems at NOAA • Systems are inadequate for climate observations • Current thrusts focus on atmospheric composition rather than Climate forcing [even though forcing is 20% of budget]

7. Meeting notes (2) NOAA Arctic Issues FY08 - FY12 • Approaches to Modeling, Reanalysis, etc. need discussion Climate impacts on Fisheries • Bering Sea focus • NCPREP information is being provided to various groups • Range/regime shifts need to be investigated • PMEL providing climate change predictions for the next 3-5 years

8. Meeting notes (3) Planning for Climate Data Records • Greater Integration across NOAA programs including observations, validation and modeling • Need for improved inter-agency collaboration, e.g., NASA • Long Term Data Records - efforts should include prospective and retrospective activities, not simply retrospective • Should maintain a summary of NRC recommendations and NOAA responses • SDS should document CDRs it will be responsible for • Performance measures need development /linkage to societal benefits • Validation needs more visibility in the overall CDR process • Reanalysis - a national strategy and the SDS role need definition • Community Reanalysis Code and Reanalysis product linkage should be developed • Data management strategy to support reanalysis should be defined • Data and Observation systems - WG needs regular updates on CLASS • Relationships between CLASS and GEOSS need to be articulated with respect to data synthesis and analysis

9. Meeting notes (4) Community Re-analysis Project • Community Re-analysis - Phil Arkin proposal • Explore a Community Reanalysis Code (CRC) and a Community Reanalysis Database (CRD) • Coordination with Joint Center for Satellite Data Assimilation • May require a WG to develop the concept of a CRC/CRD fully

10. SAB Actions • Articulate linkages between CWG and other SAB activities, i.e., Working Groups • Accept the Climate Working Group Report and provide feedback on the commentary
