Greenland mass ice balance

WebThe 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 approximately … WebTotal Ice Mass Balance. GRACE satellite data can be used to estimate monthly changes in the total mass of the Greenland ice sheet, as done in the past (e.g., Tedesco et al., 2024). However, the NASA GRACE mission, which started in 2002, ended in October 2024. Hence, there are no data available on the total mass balance for the 2024/18 season.
