Gridded surface elevation changes from multi-mission satellite altimetry 1978-2017
Here we provide a 10x10km grid of monthly surface elevation changes (SEC) of the Antarctic Ice Sheet from our multi-mission satellite altimetry combination. Covering the period 1978-2017, the contributing satellite missions (Seasat, Geosat, ERS-1, ERS-2, Envisat, ICESat and CryoSat-2) provided measu...
