Road Map of the high-end Earth System Modeling
2006-2013: The “Geodesic Grid” Planet Simulator, 3rd 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.

• 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

Now back to TIM: Overview
• Review of Analysis System Sustainment - Steve Albers
• Review of Model System Sustainment -

• Issues

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.
