Initial results of CryoSat-2 data from the Arctic
We examine SAR L1b data from the commissioning phase, currently available for the calibration and validation teams. We use CryoSat-2 data to detect leads in the sea-ice in an area north of Svalbard. Furthermore, we classify the sea-ice from computed freeboard values, and evaluate the coherence betwe...
