Monthly reference distribution of daily relative sunshine values

Abstract In this paper it is shown that for a given location the monthly distributions of the daily relative sunshine depend only, within statistical errors, on their monthly averages and are independent of the month of the year. Furthermore it is put in evidence that a reference distribution of the daily relative sunshine values for every month of the year can be found by the knowledge of the average deduced from data of some years.
