Abstract

The amounts of radiations received from the sun at 42° N. latitude at various hours of the day throughout the year, both in the visible spectrum and in the ultra violet, were determined experimentally. Curves are plotted and tables are given to show what percent of the total comes from the sky alone in each of these regions of the spectrum. From these data, one may determine the relative amounts of ultra violet or visible radiations received at any two periods of the day or year either from sun and sky combined or from one of these alone.
