DAILY SUMS OF GLOBAL RADIATION FOR CLOUDLESS SKIES,
COLD REGIONS RESEARCH AND ENGINEERING LAB HANOVER N H
Quantitative information on global radiation for studies pertaining to the distribution, accretion, and ablation of ice and snow, thawing of soils, evaporation, and climatology is given in tables containing radiation received on a horizontal surface under cloudless skies. Sums of global radiation were computed as a function of geographic latitude, declination of the sun, precipitable water content of the atmosphere and atmospheric dust attenuation to the solar beam. A method of computation published by W. H. Klein 1948 for determining global radiation inside the atmosphere was followed. Expressions are given for determining 1 daily sums of extraterrestrial solar radiation, 2 daily solar radiation at the surface of the earth, 3 atmospheric transmission as a function of the optical airmass, 4 the effect of dust attenuation on solar energy, 5 daily sums of direct solar radiation at the surface of the earth, and 6 total precipitable water vapor content of the atmosphere.
