Ice-sheet mass balance in central West Greenland

Updated 2000-09-25

The aim of the project is to obtain more insight in the response of the Greenland ice sheet to climatic change. For this purpose we will link our surface energy-balance model to an atmospheric model, so that the model can be forced by variables characterizing the atmosphere outside the thermal influence of the ice sheet itself. The modelling is supported by the mass-balance and meteorological data that we collect along a transect in West Greenland (the Kangerlussuaq-transect or K-transect). The albedo of the ice sheet is studied by means of satellite data and measurements obtained from a helicopter. Research activities - develop numerical models of the surface energy balance and the boundary layer above the ice sheet - perform annual measurements of the mass balance and ice velocity along the K-transect - maintain two automatic weather stations along the K-transect - study the surface albedo by means of remote-sensing images - improve methods to retrieve the surface albedo from satellite data by means of measurements obtained from a helicopter
