Scholarcy highlights
- Between total solar radiation on a horizontal surface and hours of bright sunshine 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 Ångström equation at each latitude ϕ over the range 0° - 60° is derived and is shown to give values in reasonable accord with previous experience
