Greenland Ice Sheet annual mass changes from joint inversion of gravimetry and altimetry

Data sets released are 2-year mean annual mass changes over the Greenland ice sheet, derived from joint inversion of gravimetry (GRACE, GRACE-FO) and altimetry (CryoSat-2) data. Unit is mm water equivalent per year. The data product covers the period from 2011 through 2020, with a two-year data gap (2017-2018) due to a lack of GRACE/GRACE-FO data.
