Here you can find information on how to configure and run EAMxx, E3SM’s convection-permitting atmosphere model, which is written in performance-portable C++ and will become the ATM component for E3SMv4.
EAMxx has a high-resolution configuration called “SCREAM (Simple Cloud-Resolving E3SM Atmosphere Model)”. In fact, EAMxx was originally named SCREAM, so several of the resources below refer to SCREAM instead of EAMxx, but the two actually refer to the same atmospheric model.
