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

The Quick Start page includes instructions on obtaining the necessary code and input data for model setup and execution.
E3SM is high-performance computing application and generally requires a cluster with several hundred nodes 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.
Please refer to Running E3SM for instructions on running the model.
Please refer to Contributing for details on our code development process for submitting pull requests.
The Energy Exascale Earth System Model (E3SM) Project should be acknowledged in publications as the origin of the model using these guidelines.
In addition, the software should be cited. For your convenience, the following BibTeX entry is provided.
