The Ice Sheet Mass Balance Inter-comparison Exercise (IMBIE), an international team of 89 polar scientists led by Andrew Shepherd from the University of Leeds and Erik Ivins at NASA’s Jet Propulsion Laboratory, compared and combined data from 11 satellites – including ESA’s ERS-1, ERS-2, Envisat and CryoSat missions, as well as the EU’s Copernicus Sentinel-1 and Sentinel-2 missions – to monitor changes in the ice sheet’s volume, flow and gravity.
The most complete picture to date of Greenland ice loss is detailed in a paper published in Nature.
