GMAO Science Snapshot - 2021 Greenland Ice Sheet Melt Events: A Variety Pack

The summer of 2021 is remarkable for a series of late-summer melt events that have covered large areas of the Greenland Ice Sheet, even extending to its highest point at Summit Station. These events have been captured in the GMAO Forward Processing (FP) analyses and in routine numerical weather predictions produced from the GEOS forecast model, running at the NASA Center for Climate Simulation (NCCS).
