EAM User Guide - E3SM
EAM User Guide. This User Guide describes how to set up and run EAM. Steps to build and run EAM. EAM is not available as a standalone model. Instead, EAM can be run in an atmosphere-only configuration. The difference when running in atmosphere-only mode (without an interactive ocean or sea-ice) would be to change the compset and grid.

Exascale Performance of the Simple Cloud Resolving E3SM …
2023年2月28日 · Achieving 1 SYPD on an Exascale machine represents a breakthrough capability that has been a longstanding E3SM goal. The E3SM Atmosphere Model in C++ (EAM xx): This performance was made possible by years of work developing the EAMxx code base used by SCREAMv1.
Predicted Particle Properties - E3SM
The current version in E3SM is a two-moment scheme with a single ice category (Morrison & Milbrandt, 2015). 1 In addition to the total ice number and mass mixing ratios, P3 prognoses the rimed mass and rimed volume mixing ratios, which allows for the prediction of the continuous evolution of the rime fraction and particle density.
