An eddy-permitting ocean-sea ice general circulation model (E3SMv0-HiLAT03): Description and evaluation
We document modeling setups and present results for simulated ocean and sea ice climate from a recently developed, intermediate-resolution global ocean-sea ice model [Energy Exascale Earth System Model version 0 configured for High-Latitude Application and Testing at 0.3° resolution (E3SMv0-HiLAT03)...

Analyses focus on ocean temperature and salinity fields, ocean dynamics and circulations, sea ice concentrations and thicknesses. The HiLAT03 model does reasonably well in most oceanic aspects evaluated here, especially in ocean meridional heat transport, despite the fact that no explicit eddy parameterization is applied. Many Arctic sea ice features are much improved compared with the 1° NCAR model, but the Antarctic summer sea ice is still generally low in concentrations and thicknesses.
