font face="Times New Roman"> Broadband Ultraviolet-B (UV-B, 280-315 nm) and total (300-3000 nm) radiation measurements and calculations have been carried out in Córdoba City, Argentina (31º 24´ S, 64º 11´ W, 470 meters above sea level) between November 1998 and December2002. UV-B measurements were carried out with a YES UVB-1 radiometer while calculations were performed by using the Tropospheric Ultraviolet Visible model (TUV 4.1). Total measurements were taken by using a YES TSP-700 pyranometer and the calculations by using a parameterization. The site selected for the measurements represents semi-urban conditions and is along the most frequent wind direction (NE-SW) respect to the city center. For clear sky days, calculations showed a good agreement with measurements. However, this study showed a substantial reduction (up to 50%) in the UV-B radiation on days with high levels of aerosols. The default aerosol properties included in the model did not account for the o
