:comment = "This dataset was produced using ice sheet surface runoff output from the MAR regional climate model, forced at its lateral boundaries by CMIP5 model IPSL-CM5A-MR for RCP 8.5. It is assumed that runoff enters the subglacial hydrologic system, delineated using present-day geometry, and is routed to the ice sheet margin. Spatially-varying runoff is summed over each marine-terminating glacier’s catchment and each grid cell within a particular catchment is filled with the summed value. The values are extrapolated by three 1-km grid cells beyond the present-day ice sheet margin. This allows ice sheet models to sample runoff at any simulated location of a glacier terminus, whether it is retreating into the catchment or advancing slightly beyond the margin." ;
:info = "Basin-cumulative runoff values are adjusted for a bias between MAR climate model output and an estimate of runoff from the RACMO2.3p2 regional climate model, forced at its boundaries by ERA-Interim atmospheric reanalysis, over the time period from 1995 to 2014. This dataset was prepared by the ISMIP6 Greenland Ocean Forcing Working Group." ;
