Mass Balance and Velocity Data for Greenland Ice Sheet at High Elevations
17 Sep 2021 | | Contributor(s):: Beata Maria Csatho, Ash Narkevic, Ivan Parmuzin
This is an estimation of mass balance of the Greenland Ice Sheet at higher elevations, computed as the difference between the estimated annual total snow accumulation and ice discharge. Measurements are taken at 161 stations located 30 km apart, at 2000 m elevation that circumnavigates Greenland....
