SAR Polar Ocean DTU Cryosat Data

Coverage:  The whole Arctic region North of 65 deg N 

Time Period: All Baseline B data available by later 2013

Cryosat-2 Data Products Used:ESA SAR Baseline B L1b

Method: 
The performance of three existing retrackers that have already been applied to Cryosat-2 SAR data over sea ice will be investigated. These include a number of threshold retrackers, an OCOG retracker and a 5-parameter beta-retracker. In addition, DTU Space will implement a new leading-edge retracker, which has already produced very good preliminary results for Cryosat-2 SAR waveforms ([Idris and Deng, 2011], Coastal Altimetry Workshop, San Diego). This analysis could form the basis for possible reprocessed L1B products by ESA using more robust retrackers in the Polar Ocean.
