sunshine for a major city in each of the fifty States. This data is
not available in chart form.

percentage of possible sunshine annually.

The following figures are annual percentages of possible sunshine for
each of the 50 states.  Scientists keep records of daily sunshine. At
weather stations throughout the country, the percentage of possible
sunshine is calculated monthly and then averaged annually.
