Greenland Ice Sheet Surface Air Temperature Variability: 1840–2007*
Meteorological station records and regional climate model output are combined to develop a continuous 168-yr (1840–2007) spatial reconstruction of monthly, seasonal, and annual mean Greenland ice sheet nearsurface air temperatures. Independent observations are used to assess and compensate for syste...
