15. 15 Plans for Weather Research and Forecast (WRF) model Developmental Test Center (DTC) are progressing. GSD working with NCEP on the Rapid Refresh operational model. Continuing RUC

16. 16 Road Map of the high-end Earth System Modeling 2006-2013: The “Geodesic Grid” Planet Simulator, 3 rd generation non-hydrostatic finite-volume model with 1-4 km or finer resolution. Cumulus parameterization-free, cloud and gravity-wave resolving; will revolutionize climate modeling. Coupling to eddy resolving ocean model (JPL). Scalable to over 40,000 CPUs. Icosahedral Horizontal Coordinate Primary model for: Medium Range Weather Prediction 0 to 2 weeks, including improve hurricane track and intensity. Seasonal to Inter-annual Prediction 2 weeks to 2 years Decadal to Centennial projection A project between GFDL, ESRL, AOML to develop the leading global model in the world.

20. 20 GSD Summary ESRL Global Systems Division Will continue the mission of FSL Systems; Modeling and Assimilation; Observations; Data Systems; Advanced Computing Will expand upward to global scale concerns Will concentrate on probabilistic post processing Will collaborate with other ESRL divisions in Chemistry Phenomena Climate Will continue to seek cooperation with other agencies and the private sector

21. 21 Now back to TIM: Overview Review of Analysis System Sustainment - Steve Albers Review of Model System Sustainment - Chris Anderson Issues Discussion

22. 22 Issues Completion of Verification System –Is this a small enough addition to fit within “sustainment”? –Still have to have ranges specify a target computer platform Ingest of Level III radar data –Assume that if we have code that is prepared for new data, that this fits within a sustainment activity.
