Abstract
Ultraviolet data from Rochester, Schenectady and Whiteface Mountain, New York, for the period November 1975-December 1977, have been studied to ascertain the importance of extraterrestrial ultraviolet (UV) radiation, sunshine, cloudiness and haze on received ultraviolet radiation. The first three factors can be shown to have great influence on received UV, while haze cannot be shown to selectively attenuate UV. It appears that there is a linear relationship between sunshine duration and received UV, with a correlation coefficient of 0.88 for the data studied.
