Abstract
Abstract The Thornton–Running algorithm to estimate daily global radiation was tested at a site in a coastal desert of the eastern Mediterranean. In this algorithm three factors are multiplied in order to compute the daily global radiation: the total daily extraterrestrial radiation impinging on a horizontal plane, the maximum daily total atmospheric transmittance possible on days with clear skies (Tt,max), and the realized proportion of Tt,max for days during which the sky is not clear (Tf,max). Estimates of Tt,max compared very well with measured values while this was not the case for Tf,max. A good correlation was, however, obtained between predicted and measured values of daily global radiation with a noticeable underprediction of global radiation when measured values exceeded 20 MJ m−2. A regression analysis showed that errors in the estimated global radiation were linearly related to errors in Tf,max. Analysis of the data used in this study indicated that for the conditions prevailing in the area it...
