1. CISL/DSS & MMM Data Discussion 19 March 2009

2. Who CISL/DSS - maintain NCEP operational analyses and observation datasets – Gregg Walters, Doug Schuster, Steven Worley (Manager) MMM – know about user support and needs of the WRF and MM5 community – Cindy Bruyere, Hui-Chuan Lin

3. Why Coordinate dataset development with the significant user group associated with WRF and MM5 – Terminating time series extension of datasets in some historical formats, e.g. ON29 – Clarify our presentation of datasets – Clarify what data is available in the Research Data Archive (RDA) – Learn about current/future data requirements for MM5 and WRF – Work with MMM to assure good data guide documents for RDA resources

4. Approach Summarize the RDA resources in three categories 1.NCEP Observations 2.NCEP Operational Analyses 3.Reanalyses

6. Platform Observational Dataset Specifics

8. NCEP Operational Gridded Dataset Specifics * Unidata IDD Models include Global: GFS 0.5 deg, GFS 1.0 deg, GFS 2.5 deg; Regional: NAM 12km, RUC 20km

10. Reanalyses Dataset Specifics
