| Description: |
Extraterrestrial radiation is attenuated by the atmosphere in different proportions depending mainly on the solar zenith angle and the altitude of the measurement point. In this work, very high and extreme total solar irradiance measurements are presented that, on some days, surpassed the Solar Constant corrected by the actual Sun-Earth distance (CSC). This paper reports a detailed analysis of ground-based measurements of cloud-enhanced solar global irradiation in NE Brazilian cities. [Source: Renewable Energy]
