Solar radiation on the south coast of England

Abstract

AbstractThree years' data of incoming measured solar radiation at the Glasshouse Crops Research Institute are used to assess the radiation climate of the south coast. Radiation in both summer and winter is higher than at other stations in this country; this is, however, only partly attributable to the longer duration of sunshine because radiation is higher than would be expected from the longer duration of sunshine alone. A similar effect at Aberporth results from clean air, but despite the low level of pollution on the south coast, peak clear‐weather values are not abnormally high. Supplementation occurs on days that are not wholly clear; it is suggested that this is a result of reflection from orographic cloud.
