The E3SM project began in 2014 with a 10-year vision of modeling the earth system on exascale computers. That bold decadal vision was achieved in 2023 and was recognized with a Gordon Bell Prize.

We are very proud of what the project team has accomplished and look forward to celebrating this decade of progress.

Version 3.0 of the Energy Exascale Earth System Model was formally frozen and tagged in the project repository in March, 2024. After this date, only maintenance and bug-fix updates will be made to this version.

A patch release v3.0.1 and v3.0.2 were announced in Oct in Dec 2024 respectively. The main purpose of these releases is to introduce additional compsets used in v3 simulations and to fix few bugs found in compsets released with 3.0.0.

Users of v3 are requested to delay submitting papers that use the new version or any new feature (that may be turned off in the code) until the project submits a publication on its new development (within approximately 6 months to a year), thereby creating a peer-reviewed article for reference. Please read the project Policies and Acknowledge E3SM.

In May 2024, the E3SM project, supported by the US Department of Energy’s (DOE’s) BER EESSD ESMD program held its first in-person tutorial workshop at the National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Lab in Berkeley, CA. This workshop was designed for new users engaged in currently funded BER’s EESSD projects, and other related DOE projects. The recordings, presentations and practicum material is now available.
