Abstract
A simple quadratic correlation, which is obtained from a universal Angstr¨om-type quadratic relation, between daily horizontal global solar irradiation and satellite images is presented. The performance of this correlation is seen to be in the acceptable accuracy limits for daily estimates. In addition, by using data from 5 locations in Turkey, a linear correlation between the bright sunshine hours and satellite based cloud index is derived. Utilizing these 2 correlations, one can easily obtain spatial daily solar irradiation and sunshine duration maps for the regions with similar latitudes and climates of locations of interest
