Energy Exascale Earth System Model

The Energy Exascale Earth System Model (E3SM) , formerly known as Accelerated Climate Modeling for Energy (ACME) project is an ongoing, state-of-the-science Earth system modeling, simulation, and prediction project, sponsored by the U.S. Department of Energy’s (DOE’s) Office of Biological and Environmental Research (BER), that optimizes the use of DOE laboratory resources to meet the science needs of the nation and the mission needs of DOE. A major motivation for the E3SM project is the coming paradigm shift in computing architectures and their related programming models as capability moves into the exascale era. The E3SM model simulates the fully coupled climate system at high-resolution (15-25km) and will include coupling with energy systems, it has a unique capability for variable resolution modeling using unstructured grids in all its earth system component models.

E3SM coupled model simulation output data will be released as the simulations conclude. 

Published data:

Lower-resolution water cycle (1 deg atmosphere, 30-60 km ocean) CMIP6 DECK experiments:

High-resolution water cycle (0.25 deg atmosphere, 18-6 km ocean) HiResMIP-like experiment  

To be published soon:

Lower-resolution water cycle (1 deg atmosphere, 30-60 km ocean) CMIP6 DECK experiments:

  • Historical simulation 1850-2015 (4 ensemble members) 
  • Abrupt 4xCO2 simulation (150 years)
  • 1% per year CO2 increase up to doubling (150 years)
  • AMIP simulation.

 

Planned simulations, to be started soon:

BGC coupled simulation (lower resolution) 

Ocean-cryosphere simulation (variable resolution)
