Abstract This study aimed to write a mathematical model that contributes to providing all points of change for solar radiation according to variation in the angle of solar elevation. This work proposed a model sufficient to predict the solar radiation on a horizontal area in different contexts and added air pollution such as CO, CO2, and CH4 linked with parameters such as ηbeam, κbeam, κdiffuse, β, and TL, which represent a new pollution factor that defines the mathematical model according to two components, direct and diffuse radiation. We know that the effect of pollution on light is achieved by absorbing solar radiation, which obscures part of it, and the rest of the radiation crosses the Earth’s atmosphere at a limited rate, which encouraged us to take into account the pollution side and the equation is comprehensive and sensitive at the same time. We recorded the largest value of CO2 in April and December at an estimated value of 408 (μmol/mol), where the diffuse radiation rate is low, and this coincides with the CO. Finally, we reached satisfactory results, as they were markedly identical and with almost no errors. Keywords A new factor of pollution . Prediction . CO2 . CO . CH4 . TL
