An important parameter necessary for describing the microclimate or heat budget at the earth's surface is the quantity of incident solar radiation. However, measurements of radiation on other than a horizontal surface are not normally available. This article provides a set of tables listing the ratio of total daily solar energy received on a surface of given aspect and slope to that received on a horizontal surface at latitude 37° 30' S. By multiplying this figure by the total short wave radiation recorded on a horizontal plane subject to similar cloud and atmospheric conditions, daily or monthly values of solar radiation on a sloping surface may be approximated. © 1976 Taylor & Fracis Group, LLC.
