Observing

The global observing system must be designed to support the scientific questions inherent in long term climate diagnosis and prediction.

The strategic triad of global observing:

Satellites – UAVs - Buoys

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.

GSD SummaryESRL 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

Now back to TIM: Overview

• Review of Analysis System Sustainment - Steve Albers

• Review of Model System Sustainment -

Chris Anderson

• Issues

• Discussion

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.
