Abstract
A technique is presented for estimating monthly sums of global radiation from a combination of calculations of monthly cloudless global radiation, surface meteorological observations, and empirical equations relating sunshine to global radiation. The percent deviation of calculated from observed values is not negligible but is much less than errors obtained using extraterrestrial solar radiation sums. If monthly global radiation is estimated for areas other than the one area described here, the possible errors should be redetermined. Techniques to adapt the equations for other areas are discussed.Keywords
