http://polarportal.dk/en/news/news/surface-mass-balance-of-the-greenland-ice-sheet/ WebIn this paper, we present a time series of the annual surface mass balance (SMB) of the Greenland ice sheet for the period 1866–2005. Values of SMB are quoted with respect to the average value for the 1961–90 climatological normal period. In addition, we report on how the spatial patterns of SMB vary over specified historic time intervals.
