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...

| Summary: | 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 cost function we arrive at a measure of the obtained change in quality of model results. In this respect the sea ice component of the MITgcm is compared with and without an activated ITD parameterisation. |
