Precipitation	van der Veen, Bromwich, Csatho and Kim (2001)	This data is in meters/year (water equivalent). The grid was obtained from the following components: (1) Geographic trend surface derived from multivariate regression of accumulation; (2) Geometry effect regressing the geographic trend residual on the first and third principal components characterizing the ice sheet geometry; (3) Kriging interpolation of residual=[accumulation (ice cores and pits) or precipitation (coastal stations) - geometry and geographic effects] (4) Sublimation from Box and Steffen (2001). netCDF, CF 1.3.
