A long term study of the relations between erythemal UV-B irradiance, total ozone column, and aerosol optical depth at central Argentina

Autor: Luis E. Olcese, Mariana Achad, Gustavo Gerardo Palancar, María Laura López, Beatriz M. Toselli

Global ultraviolet-B irradiance (UV-B, 280–315 nm) measurements made at the campus of the University of Córdoba, Argentina were analyzed to quantify the effects of ozone and aerosols on surface UV-B erythemal irradiance (UVER). The measurements ha
