摘要

The CryoSat Validation Experiment (CryoVEx) has beenrnconducted by ESA, to examine the uncertainties in thernsatellite measurement of e.g. sea ice thickness. Inrnthis study, we aim to estimate the sea ice freeboardrnfrom CryoSat-2, and compare it with the high-resolutionrnAirborne Laser Scanner (ALS) measurements collectedrnalong CryoSat-2 ground tracks from the CryoVEx 2012rncampaign, together with NASA’s Operation IceBridgerndata. We will use the CryoSat SAR data level 1b (L1b) torndiscriminate the leads and from this, estimate the sea icernfreeboard. Furthermore, we are looking at the CryoSatrnlevel 2 (L2) product, and correcting the extremely offrangingrnpoints.
