E3SM: Improved Climate Prediction with Exascale Capability

Summary

The Energy Exascale Earth System Model (E3SM) project is an ongoing initiative by the U.S. Department of Energy to enhance climate prediction capabilities using exascale computing. The core challenge is to achieve greater accuracy in climate simulations, particularly for global and regional water cycles. A new Multiscale Modeling Framework (MMF) has been developed to improve cloud representation by running 1-3 km resolution cloud models within E3SM's existing 25-100 km global grid. This approach allows the global model to maintain throughput rates of over 5 simulated years per day while achieving unprecedented accuracy, enabling better predictions for policymakers. This work is supported by the Exascale Computing Project (17-SC-20-SC) under Contract DE-AC52-07NA27344.
