Title

Evaluation of the effects of atmospheric pollutants on the performance of Angestrom-Prescott equation in estimating solar radiation (Case Study: Karaj)

Pages

  1053-1061

Abstract

 According to the fact that the solarimeteric stations are sparse, and the importance of awareness about solar radiation values, it is necessary to develop Solar radiation models based on other meteorological variables. The empirical Angstrom-Prescott equation-which is based on sunshine hours-is widely used for the estimation of solar radiation. Although many studies have been conducted in order to validate the coefficients of this equation for each region in Iran based on the specific meteorological conditions of sites, the role of air pollution as an important parameter to reduce the radiation received from the sun has not been addressed yet. In this article, the validation of A-P equation was carried out based on the 3-year data of Karaj station in a daily time scale, considering the Air pollution index through the logarithmic, linear and exponential equations. The research results showed that the corrected models with logarithmic structure with the determination coefficient of 0. 5911 were performing better than the original Angstrom-Prescott models.
