Greenland ice sheet mass balance assessed by PROMICE (1995–2015)
The Programme for Monitoring of the Greenland Ice Sheet (PROMICE) has measured ice-sheet elevation and thickness via repeat airborne surveys circumscribing the ice sheet at an average elevation of 1708 ± 5 m (Sørensenet al.2018). We refer to this 5415 km survey as the ‘PROMICE perimeter’. Here, we a...
