Resumen:
Ultraviolet-B radiation (UV-B, 280-315) is monitored in Córdoba, Argentina (31o24´ S, 64o11´ W, 400 meters above sea level) using the Yankee Environmental Systems (YES) pyranometer, model UVB-1. Measurements of solar broad band UV-B irradiances were conduced between November 1998 and December 1999. These are, to our knowledge, the first measurements obtained in Córdoba with a high quality pyranometer. The site selected for the measurements represents semi-urban conditions and is along the most frequent wind direction (NE-SW). For clear sky days, the measurements are in good agreement with results of a radiative transfer model.  However, this study shows substantial reduction of UV-B radiation on days with high levels of air pollution.  The maximum UV irradiance measured was 2.61 W m-2. In this work we investigate the seasonal variation of UV-B radiation to assess its response to air pollution, physical variables, and meteorological factors.
