Project Description


CryoTop Evolution follows on the CryoTop project which aimed at developing and demonstrating swath processing of CryoSat-2 SARIn data. The aim of the CryoTop Evolution project is to generate an L2swath elevation product from the 2010-2016 archive of CryoSat-2 SARIn mode data, and to generate ice-sheet wide, 500m posting, Digital Elevation Models and maps of rates of surface elevation changes for Greenland and Antarctica. These data will be delivered to the community. In addition, the project will deliver science case studies pertaining to sub-glacial lakes, ice shelves thickness, calving fronts and grounding lines. The project exploits the swath processing algorithm, which consists in using the full waveform of CryoSat’s SARIn mode to generate swath of elevation, providing 1 to 2 orders of magnitude more elevation than conventional point-of-closest-approach (POCA) method. The project is in its first year and has delivered a preliminary DEM of the Greenland Ice Sheet, the first products for Greenland will be delivered in the early fall of 2017, with Antarctica following closely in early 2018.
