Linear regression equations relating the global solar radiation and sunshine duration are derived for a total of 14 stations in Peninsular Malaysia. Mean monthly global solar radiation values for other stations which have only sunshine data are estimated using these regression equations. The intensities of global solar radiation during different times of the day and under different meteorological conditions are discussed. Maps of mean monthly global solar radiation are presented and discussed. It is found that the distribution pattern of global solar radiation follows somewhat with that of rainfall pattern. Net radiation was estimated using empirical equations developed by Chang (1970), Davies (1967). Selirio et al. (1971) and Penman (cited by Chang, 1970). Comparison of the estimated net radiation with the limited net radiation record available shows that the Davies' formula gives the best estimates. Hence Davies' formula is used for the estimation of net radiation. Maps of estimated net radiation are similarly prepared and discussed.
