The Earth System Modeling Framework (ESMF) was used to couple the Los Alamos National Laboratory Community Ice Code (CICE) and the HYCOM Consortium Hybrid Coordinate Ocean Model.
This image illustrates the improvement in predicted sea ice concentrations achieved at the Naval Research Laboratory by taking a standalone sea ice model and coupling it to an ocean model using ESMF. Results were evaluated by comparing the output of the standalone and coupled versions to observations. The image shows that excess ice in the standalone version is corrected in the coupled version.
Accurate sea ice prediction is a critical global imperative, since concentrations of ice at the pole affect shipping routes, ocean circulation, sea ice levels, oil exploration efforts, and other issues with profound social and political consequences.
