Brief communication: Firn data compilation reveals the evolution of the firn air content on the Greenland ice sheet
The firn covering the Greenland ice sheet interior can retain part of the surface melt, buffering the ice sheet’s contribution to sea level, but its characteristics are still little known. Using remote-sensing observations from 2000- 2017, we estimate that firn covers 1,405,500 ±17,250 km 2 of the i...
