Abstract

E3SMv1 is the first version of DOE’s Energy Exascale Earth System Model. E3SMv1 started from CESM1 but has since undergone significant changes. E3SMv1 includes new ocean and sea ice components based on the Model for Prediction Across Scales (MPAS) as well as a new river model, Model for Scale Adaptive River Transport (MOSART). In the atmosphere, the spectral-element (SE) dynamical core replaces the finite volume option and most of the physics has been enhanced or replaced. The number of vertical levels in the atmosphere was also more than doubled from 30 to 72 levels. CMIP6 simulations were run at the standard horizontal resolution of 100km atmosphere and 60-30 km ocean.
