Greenland mass balance
WebMar 21, 2024 · The mass of the Greenland ice sheet has rapidly declined in the last several years due to surface melting and iceberg calving. Research based on observations from the Gravity Recovery and Climate Experiment (GRACE) satellites (2002-2024) and GRACE Follow-On (since 2024 - ) indicates that between 2002 and 2024, Greenland shed … WebThe 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. The Greenland Climate Network (GC-Net) was established in 1995 by Prof. Konrad Steffen at CIRES, to obtain knowledge of the mass gain and climatology of the ice sheet.
