Most of the applications already being exploited with the conventional low resolution altimeters can be improved with the SAR altimeters, thanks the better along-track resolution achieved. As Cryosat-2 was the first altimeter with SAR capabilities, most of the applications are in a development phase. Processors are being adapted and new models are being created in order to get the best performances on each case.
