While it is of academic interest as to the variations at similar latitude locations and resolving he differences in those variations surely the point of the exercise (apart from academic interest which is important) is to compare data on such things as the comparative incidence of uv damage such as skin cancer and other impacts of uv on people. I.e. plot the comparative % incidence of uv damage at a range of global locations and theorise if the differences would be explained by ‘Covering up’
