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.

The E3SM model is publicly available (see References below), it has an open source code, and the data from all major simulations will be made publicly accessible by publishing to ESGF as the simulations conclude. 

Data in E3SM project on ESGF is published in raw / native model output fromat on native grid for each component (atmosphere, ocean, ice, land and river components), as well as regridded to lat-lon grid, with calculated climatologies and few variables as time-seriers over the whole simulation period. 

The CMIP6 DECK simulations are also being published to the CMIP6 ESGF project as part of CMIP6 data holding.
