The impact of an ITD parameterisation on the quality of model results

An ice thickness distribution (ITD) parameterisation is by now part of most sea-ice models. Yet although it is based on a more physical reasoning, the gain for current models by its use is still unclear. By measuring the misfit to satellite observations for concentration, thickness and drift in a co...
