Gravity field from cryosat-2 sar altimetry: the merits of the empirical primary peak retrackers
SAR lead and ocean data from Cryosat-2 is processed using waveform retracking for estimation of gravity fields in the Arctic Ocean. The retrackers proposed in this work are based on the combination of the OCOG (Offset Centre of Gravity) and Threshold methods with Primary Peak extraction. These propo...
