In this study, an analysis of the monthly mean values of the fraction of the sky covered by clouds (C) of all types and the duration of bright sunshine hours (S) and global solar radiation on the horizontal surface (H) was carried out to establish relationship for solar radiation estimation for Bangladesh. The relationship between C and (1 − S/S0), where S0 is the maximum possible hours of suns...

tion, and thought that visual solar radiation might provide protection from developing MS. In 1970, a study from Switzerland (which is on a similar latitude in the northern hemisphere as Tasmania is in the southern hemisphere) [5] showed a higher clinical RR in winter and spring months, and a later study (also from the northern hemisphere) [6] of seasonal fluctuations in Gd-enhancing lesions on...
