Here we provide an archive of Modèle Atmosphérique Regionale v. 3.5.2 simulations over Greenland. This archive contains daily data at 20-kilometer resolution with lateral boundary forcings from the National Centers for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR) reanalysis model. Data are provided in netCDF format, where information of all variables and their units are provided within the netCDF files. See method section for more detailed description of the data. Citation: If this dataset is used in any publication, this data repository and Fettweis et al. 2017 should be cited. Contact Xavier Fettweis for obtaining more recent MAR based simulations (see contact information in metadata).
