The gridded products cover the Antarctic Ice Sheet between 2011 and 2016. These data have been processed by the University of Edinburgh and are made publicly available as part of a European Space Agency funded project involving the University of Edinburgh, isardSat UK, University of Leeds-CPOM, ENVEO. Gridded elevation and elevation change over the CryoSat-2 LRM sector of the Antarctic Ice Sheet are provided by CPOM.

The methodology is described in details in: Gourmelen, N, Escorihuela, M, Shepherd, A, Foresta, L, Muir, A, Garcia-Mondejar, A, Roca, M, Baker, S & Drinkwater, MR 2017, 'CryoSat-2 swath interferometric altimetry for mapping ice elevation and elevation change' Advances in Space Research. DOI: 10.1016/j.asr.2017.11.014 Data collection: CryoSat-2 spaceborne interferometric radar altimeter. Data quality: Validation against operation ice bridge airborne laser altimeter returns a mean difference of 0.8 m, a median difference of 0.3 m, a standard deviation of 75.4 m and a median absolute deviation of 2.8 m. asNeeded completed
