The interactive map of the solar activity database contains the monthly mean of daily duration totals of sunshine, global radiation and diffuse radiation for more than 1500 locations in all regions of the world, as well as averaged data for sky cover for the observation period between 2004 and 2014 for more than 11,000 relevant meteorological observations locations. The map was created based on the data from the World Radiation Data Center (WRDC) and Global-Historical-Climatology-Network (GHCN) of National Oceanic and Atmospheric Administration U.S.
To retrieve information, select the source name in the legend - WRDC or GHCN and click one of the active locations on the map. Depending on your initial choice, you will receive either sunshine duration, global radiation, diffuse radiation or sky cover diagrams, with a different colour highlighting the respective sky cover state fractions - clear, scattered from 1/8 to 4/8, broken from 5/8 to 7 / 8, overcast, obscured, partial obscuration.
By selecting the following layers in the legend: GHCN SKC, you can see the average values of sky cover with the corresponding colour scheme for specific geographic areas, in a cross section, measuring: latitude = 1, longitude = 0.5 (degrees), and calculated based on the data of meteorological stations located inside this cross section of the map.
