Abstract: Correlation equations have been developed to obtain the monthly average of daily global, beam and diffuse solar radiation at Karachi, Pakistan from the fraction of maximum possible sunshine hours. The global, beam and diffuse solar radiation estimated via these equations are then compared with the measured values with excellent agreement. Diffuse and beam radiation can be estimated even in the absence of global radiation.
