Solar Radiation

In this booklet, I build a mathematical model for solar radiation, between 0.3 and 5 microns, at sea level, for days without clouds, for any specified latitude and day of the year. I take into account the eccentricity of the orbit of the Earth around the Sun and the phenomenon of extinction due to the atmosphere. The Sun is initially considered a black body and then an empirical corrective factor is introduced to account for the absorption lines of the star.
