CISL/DSS & MMM Data Discussion

19 March 2009

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

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

Approach

• Summarize the RDA resources in three categories1. NCEP Observations2. NCEP Operational Analyses3. Reanalyses

Platform Observational Dataset Specifics

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
