Resolution is important for Greenland SMB. High-resolution RCMs are therefore an important tool contributing to reliable projections of sea-level rise. Now, there are a lot of papers about GrIS SMB using available RCMs. These studies made it possible to assess uncertainties in model estimates of SMB and to point out important processes (detailed snow physics scheme, e.g. albedo and meltwater refreezing). This also applies to Antarctic SMB. Sea-ice simulations from coupled RCMs help to identify key mechanisms for sea ice-atmosphere feedbacks (e. g. cyclones, albedo,…). Additionally, atmosphere data from high-resolution RCMs would be of interest for coastal erosion and frozen ground.
