Abstract

The variation with latitude of the regression parameters a and b in the conventional equation of Γ…ngstrΓΆm type
between total solar radiation on a horizontal surface (Q) and hours of bright sunshine (n) has been examined. It has been shown that the slope of the relationship b is effectively constant, while the threshold value a is a function of latitude. An empirical relationship leading to the Γ…ngstrΓΆm equation at each latitude Ο• over the range 0Β° ‐ 60Β° is derived and is shown to give values in reasonable accord with previous experience. It is
