DOE's E3SM is a state-of-the-science Earth system model development and simulation project to investigate energy-relevant science using code optimized for DOE's advanced computers

E3SM Version 2.1 is released

Version 2.1 of the Energy Exascale Earth System Model was formally frozen and tagged in the project repository on January 12, 2023. After this date, only maintenance and bug-fix updates will be made to this version and are available in the maint-2.1 branch.  Users of v2.1 are requested to delay submitting papers that use this new version until the project submits its initial v2.1 publication, thereby creating a peer-reviewed article for reference.

We ask v2.0 users to cite the main overview paper and the source code in their publications.
