CryoTop datasets


The CryoTop datasets contain surface elevation generated from swath processing of CryoSat-2 measurement. The CryoTop datasets also contain gridded products generated from the swath derived elevation, these are 2 Digital elevation models (500 m and 1 km posting) and 2 maps of rates of surface elevation change (500 m and 1 km posting) as well as associated errors. The swath elevation data are provided as NetCDF files following the naming convention of the original CryoSat-2 datafiles provided by the European Space Agency, the gridded products are provided as GeoTIFF files. The methodology and data format are described in the dataset user manual.
