This dataset contains the Greenland mass time series generated from the GRACE JPL RL05M data. The time series is a 1-dimensional time series of ice mass averaged over the Greenland ice sheet from GRACE expressed in equivalent ice mass (Gt). 1 mm of sea level equivalent equals 360 Gt of ice. The time series starts in May 2002 to present, with a lag of up to 4 months. An animation of the spatial variations can be found here. These data are available in ASCII format (Reference: Watkins et al., 2015, doi: 10.1002/2014JB011547.).
