EROSOL Robotic Network (AERONET), Moderate Resolution Imaging Spectroradiometer (MODIS) and global UV-B (280-315 nm) irradiance measurements and calculations were combined to investigate the effects of aerosol loading on the UV-B radiation reaching the surface under cloudless conditions in Córdoba, Argentina. The aerosol radiative forcing and the aerosol forcing efficiency were calculated for an extended period of time (2000-2013) at a ground-based monitoring site affected by different types and loading of aerosols. The aerosol forcing efficiency was evaluated by using the aerosol optical depth at 340 nm retrieved by AERONET at the Cordoba CETT site. The individual and combined effects of the single scattering albedo and the solar zenith angle on the aerosol forcing efficiency were also analyzed. In addition, and for comparison purposes, the MODIS aerosol optical depth at 550 nm was used as input in a machine learning method to better characterize the aerosol load at 340 nm and evalua
