Cat 5 hurricane simulated by the E3SM v0 at 13 km resolution. Precipitable water (gray scale) shows the detailed dynamical structure in the flow. Strong precipitation is overlaid in red. High resolution is necessary to simulate reasonable numbers of tropical cyclones including Cat 4 and 5 storms.

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 2.0 is Here

Version 2.0 of the Energy Exascale Earth System Model was formally frozen and tagged in the project repository on September 29, 2021. After this date, only maintenance and bug-fix updates will be made to this version. Project support and data from the v2 DECK and historical simulations will follow after the project documents its characteristics in journal articles.

Users of v2 are requested to delay submitting papers that use this new version until the project submits its initial v2 publication, thereby creating a citable reference.
