This report describes the content and format of a circumsolar radiation data base assembled by Lawrence Berkeley Laboratory. This 200-megabyte data base contains detailed intensity profiles of the solar and circumsolar region (out to 3 degrees from the sun's center), the total and spectrally divided direct normal radiation data, and the total hemispherical solar radiation in the horizontal plane and the plane facing the sun. Data are available for 11 locations in the United States covering 1976 to 1981. Measurements were made by four automatic scanning instruments called circumsolar telescopes that operated about 16 hours per day. This data base, the Reduced Data Base, was generated from a larger data set to provide data in a more manageable form. 15. Document Analysis
