Data and analyses of one year (April 1979 - March 1980) of solar radiation data from the Atlanta Georgia Tech site are presented. Specific research results deal with: (1) intercomparison of the urban Georgia Tech site with data from the rural site at Shenandoah Georgia (separation 60km, 40 miles) for global (all sky) radiation, (2) model comparisons of the Watt model and Bird model for direct beam radiation against measured data, (3) a study of relative measurement errors for the Eppley PSP, Spectrolab SR75, Lambda LiCor, and Eppley 8-48, 4) global and direct radiation regressions versus percent available sunshine, (5) comparison of Campbell-Stokes and Foster Sunshine Switch measurements with pyrheliometer derived percent available sunshine, (6) comparison of isotropic versus anisotropic sky radiation for deriving solar radiation on a tilted surface versus measured data, (7) examination of various methods for plotting diffuse radiation versus other parameters, (8) display of observed variation of ultraviolet (0.30-0.39..mu..) radiation versus global radiation as a function of relative air mass and cloud cover, (9) annual time series and regression plotting techniques, and (10) examples of probability distribution and joint probability distribution statistics for daily averages, totals, maximum or minimums. Hourly, daily, and monthly values are tabulated in an appendix for direct, direct (RG630), global, global (RG630), diffuse, latitude tilted global, ultraviolet radiation, and available sunshine, for the period April 1979 to March 1980. Monthly averages of other meteorological and radiation parameters are also tabulated for this period.
