Solar radiation model validation
Three solar radiation models have been used in developing the Augmented SOLMET Solar Data Tapes for the 26 SOLMET sites and the 222 ERSATZ Solar Data Tapes. One of the models, a theoretical one, predicts the solar noon radiation for clear sky conditions from the optical air mass, precipitable water vapor and turbidity variables. This model is referred to as the Clear Solar Noon Model. A second model, an empirical one, also developed by NOAA, predicts the hourly total horizontal radiation from meteorological variables. This model is referred to as the Total Horizontal Regression Model. And a third model, also an empirical one, predicts the hourly direct normal radiation from the hourly total horizontal radiation. This model is referred to as the Aerospace Direct Normal Model. A study of the accuracy of these solar radiation models is reported. To assess the accuracy of these models, data was obtained from several US National Weather Service Stations and other sources, used the models to estimate the solar-radiation, and then compared the modeled radiation values with observed radiation values. The most important results of these comparisons for these three models mentioned above are included. (MHR)
