Radiation data were compiled and computed from many sources in the Arctic to produce a two-part Arctic Global Radiation (AGR) data set. The first part includes a time series of monthly fluxes from land stations, ocean drifting stations and empirically derived long-term climatological estimates from earlier Russian studies. While many of the station time series are quite short, some span over 40 years. Data are provided for the region north of 60 degrees N. The second part is a long-term monthly mean gridded climatology for the region north of 65 degrees N, based on the AGR-1 data set. For the most comprehensive information on this data set, read the extensive documentation.
