RACMO2.3p3 monthly-accumulated shortwave radiation data for Greenland (September 2000–2018) C. T. van Dalum, W. J. van de Berg, and M. R. van den Broeke

Short summary
The reflectivity of sunlight, which is also known as albedo, is often inadequately modeled in regional climate models. Therefore, we have implemented a new snow and ice albedo scheme in the regional climate model RACMO2. In this study, we evaluate a new RACMO2 version for the Greenland ice sheet by using observations and the previous model version. RACMO2 output compares well with observations, and by including new processes we improve the ability of RACMO2 to make future climate projections.
