Exchange grid & multi-ice categories coupling: comparison of two flux computation strategies
We evaluate the impact on fluxes over ice, particularly non solar heat, and the coupled effects to the NEMO/GELATO ocean/sea-ice model, of a separate flux calculation by SURFEX for each of the five ice categories represented in the GELATO ice model. We compare these effects with those produced by a...
