EO4SMB has published a new study in Nature Communications, demonstrating the ability of CryoSat-2 radar altimetry to map Greenland Ice Sheet run off. This represents the successful completion of one of the core objectives of the EO4SMB, and the first use of satellite data to measure this key climate parameter from space. Using this new dataset, the study showed that over the past decade, 3.5 trillion tonnes of ice have melted from the surface of the ice sheet. It also found that year-to-year variability in melting has increased through time, along with the frequency of episodes of extreme melting. Full details of the study “Increased variability in Greenland Ice Sheet runoff from satellite observations” are available at https://dx.doi.org/10.1038/s41467-021-26229-4.
