Abstract:
The secondary objective of the Sentinel-3 Surface Topography Mission is to provide surface elevation measurements over sea ice and land ice regions in conjunction with CryoSat-2. In order to assess the present data quality of the Sentinel-3 SRAL PDGS products over sea ice and land ice, a processing of the S3 SRAL L1A products up to L2 has been carried out. The enhancement of this processing with respect the current PDGS processing baseline is to double the length in the range window and to double the resolution by means of zero-padding.
The enhanced products will be cross-compared against the PDGS products in order to highlight the role and effect of the zero-padding for freeboard computation and of the radar window extension for the tracking of the land ice margins.
A cross-comparison against collocated CryoSat-2 products will be presented. The final objective is to assess the add value brought by these two new processing options for potential implementation in the Sentinel-3 SRAL PDGS.
