title: Solar altitude frequency tables.
abstract: A table is presented that gives the total number of hours in the year during which the sun's altitude exceeds a given value h, for h = 0-88 degrees in 2 degree increments and for latitudes from the Equator to the North Pole in 2 degree increments. The table also gives corrections to these figures for the effect of atmospheric refraction and the total hours of daylight at each latitude
