Accuracy and Performance of CryoSat-2 SARIn Mode Data Over Antarctica
The instrument onboard CryoSat-2 has a new measurement mode to improve performance on the steeper margins of the ice sheets where conventional radar altimetry has been limited in accuracy and coverage. We assess the accuracy of CryoSat-2 synthetic aperture radar interferometric (SARIn) mode data usi...
