Programme for monitoring of the Greenland ice sheet
In 2007, Denmark launched the Programme for Monitoring of the Greenland Ice Sheet (PROMICE) to assess changes in the mass balance of the ice sheet. The two major contributors to the ice sheet mass loss are surface melt and a larger production of icebergs through faster ice flow. PROMICE is focused on both processes. Ice movement and discharge is tracked by satellites and GPSs. The surface mass balance is monitored by a network of weather stations in the melt zone of the ice sheet, providing ground truth data to calibrate mass budget models. Currently, PROMICE operate more than 20 automatic weather stations installed on the ice sheet. The weather stations measure all the important meteorological parameters, but also ice ablation, snow accumulation, ice temperatures, ice movement, and more.
