Estimating the Solar Irradiance of an Intermountain Region Using GOES (Geostationary Operational Environmental Satellite) Satellite Data: a Test of Two Statistical Models.

Pagination or Media Count:
The performance of two statistical models that use satellite data to calculate the global solar radiation incident upon the earths surface are assessed. The estimates are determined for a mid latitude ten station network and represent a variety of sky cover conditions. Evaluations of the models for different sky conditions reveal the need for revised regression coefficients for the Hay and Hanson 1978 model and the Tarpley 1979 model. The Hay and Hanson 1978 model was shown to perform better for partly cloudy and overcast sky conditions while the Tarpley 1979 model performed better under clear skies. On a hourly and daily time scale, the Hay and Hanson 1978 model proved to be the better performer.
