Energy Exascale Earth System Model (E3SM)

E3SM is a state-of-the-art fully coupled model of the Earth System including
important biogeochemical and cryospheric processes. It is intended to address
the most challenging and demanding earth system research problems and
Department of Energy mission needs while efficiently using DOE Leadership
Computing Facilities.

DOI: 10.11578/E3SM/dc.20240930.1

Please visit the project website or our Confluence site
for further details.

For questions about the model, use Github Discussions.

See our Github-hosted documentation at https://docs.e3sm.org/E3SM.

Table of Contents

Quick Start

The Quick Start page
includes instructions on obtaining the necessary code and input data for model
setup and execution on a supported machine.

Supported Machines

E3SM is a high-performance computing application and generally requires a
capable compute cluster to run a scientifically validated case at a useful
simulation speed.

To run E3SM, it is recommended that you obtain time on a
Supported Machine.

Running

Please refer to Running E3SM
for instructions on running the model.
