Monaghan, A. J., D. H. Bromwich, and S.-H. Wang. 2006. Recent trends in Antarctic snow accumulation from Polar MM5 simulations. Philisophical Transactions of the Royal Society A 364: 1683-1708.

Resolution: 60 km
Time Period: 1985-2001
Sources: Polar MM5 mesoscale model simulations with initial and boundary conditions provided by the European Centre for Medium-Range Weather Forecasts (ECMWF) 40-year Reanalysis (ERA-40)
Units: mm·a-1, or kg·m-2·a-1, snow water equivalent (SWE)
Background: Polar MM5, a mesoscale atmospheric model optimized for use over polar ice sheets, is employed to simulate Antarctic accumulation in recent decades by subtracting model-simulated precipitation from sublimation. (Negative values therefore indicate areas where sublimation is greater than precipitation.)
