SummaryPredictions of the future Arctic climate are highly uncertain because of obvious discrepancies between IPCC models and observations. The observation of sea ice thickness and the improvement of parameterizations in climate models are thus important aims to increase our understanding of the Arctic climate system. The aim of this project is twofold: 1) to contribute to the observational sea ice thickness data record and 2) to generate a statistical distribution of lead width occurrences for improved parameterizations of the tubulent ocean-ice-atmosphere interaction. TerraSAR-X data will be used together with co-located CryoSat-2 waveforms in order to derive an optimized lead classification. The work will be embedded in several ongoing research projects, like the BMBF funded project "Scale dependent parameterization of processes in the atmospheric boundary layer over arctic sea ice (MIKLIP/SPARCS)", the Cluster of Excellence CliSAP-2 research topic B1 "Arctic and Permafrost", the ESA funded project SMOSIce, and the BMWi funded project Ice Route Optimization (IRO-2).
