Description Annual (April to April) elevation change rates of the Greenland Ice Sheet from April 2011 to April 2020 from CryoSat-2, ICESat-2 and NASA’s ATM flights on a 1x1 km grid. Methods We have used radar altimetry data from ESA’s Earth Explorer CryoSat-2 mission (Wingham et al., 2006) to estimate annual mass changes of the GrIS from April 2011 to April 2020. We supplemented CryoSat-2 data with laser altimetry observations from NASA’s Operation IceBridge Airborne Topographic Mapper (ATM) flights from April 2011 to April 2019 (Studinger et al., 2020). NASA ended its Operation IceBridge measurement over Greenland in spring 2019, so to fill the gap in laser altimetry data, we used Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) data from April 2019 to April 2020. We applied corrections for the Earth’s immediate elastic response to contemporary ice mass changes and a correction for glacial isostatic adjustment (GIA) using a recent model entitled “GNET-GIA” (Khan et al., 2016). We converted the observed ...
