This data set includesthe materials required to reproduce the figures and tables presented in the study: "North Atlantic cooling is slowing down mass loss of Icelandic glaciers". The data consist of: 1.Maps of annualsurface mass balance (SMB) ofIcelandic glaciers and ice caps (ICL) from RACMO2.3 at 500 m spatial resolution in NetCDF format. smb_rec.1958-2019.RACMO2.3-ERA.ICL-0.5km.YY.nc : annual cumulative SMB of Icelandic glaciers and ice caps (kg m -2 or mm w.e. per year) from RACMO2.3forced by ERA reanalysesfor theperiod 1958-2019, and further statistically downscaled to 500 m spatial resolution. Forcing includesERA-40 (1958-1978), ERA-Interim (1979-2018) andERA5 (2019) reanalyses. smb_rec.1958-2099.RACMO2.3-CESM2-SSP85.ICL-0.5km.YY.nc :annual cumulative SMB of Icelandic glaciers and ice caps (kg m -2 or mm w.e. per year) from RACMO2.3forced by CESM2 for the historical period 1958-2014 and byCESM2 under a high-end warming scenario SSP5-8.5 for the period 2015-2099, further statistically downscaled to 500m spatial resolution. Topo_icemask_lsm_lon_lat_ICL-0.5km.nc :mask file including an ice mask,land/sea mask and surface topography derived from the ArcticDEM, and longitude/latitude coordinates on the 500m grid. NB : theNetCDF files above use aPolar Stereographic North (EPSG:3413) projection witha horizontalresolution of 500m x 500m. The reference point is located at 45ºW longitude and 70ºN latitude. 2.Time series ofannual ICL-integratedSMB components(Gigatons or Gt per year),annual mean 2 m air temperature above Icelandic glaciers and ice caps(T2m; K), annual mean sea surface temperature (SST) in the Northern Blue Blob. These time series are available in ASCII format for the RACMO2.3 simulation forced by ERA reanalyses (1958-2019) and the RACMO2.3 projection forced by CESM2 under a high-end warming scenario SSP5-8.5 (1958-2099).
