摘要：

Following the manner of Prescott, most regression equations relating solar radiation to sunshine hours involve a factor a + bn/N, where a and b are constants dependent on the climate and the locality, and n/N represents the ratio of actual to potential duration of sunshine. Examination of the several published values of a and b shows that a is related linearly, and b is related hyperbolically, to the appropriate mean value of n/N. Use of these relationships to establish values of a and b results in a formula which provides more accurate estimates of radiation from sunshine data than by the extrapolated use of existing formulae. © 1978.
