Abstract
Our calculation program based on the Iqbal formula integrates the solar irradiance during all the hours of the day, taking into account the position of the sun, the latitude of the studied site and total optical thicknesses (TOT) extracted from the AErosol RObotic NETwork database AERONET, to find the attenuation of the solar irradiance by the atmosphere. The cloudless atmosphere reduces the incident solar irradiance in the equatorial zone, characterized by a more regular meteorology, by about 30%. In temperate zones, the attenuation is variable, up to 50% in regions subject to desert dust and anthropogenic emissions (Delhi case). We can also observe weak attenuations of about 22% due to the low aerosol load (La_Laguna case).
