he Ultraviolet B (UV-B, 280–315 nm) and total (300–3000 nm) irradiances in a suburban site in C!ordoba city (31.44º S; 64.19º W) were measured and calculated between November 1998 and December 2002. Measurements were carried out with a pyranometer YES UVB-1 (UV-B) and a pyranometer YES TSP-700 (total) while UV-B calculations were performed by using the radiative transfer model TUV 4.1 (Tropospheric Ultraviolet Visible). The evolution and characteristics of total ozone column values over C!ordoba during the last 12 years was analyzed. The stratospheric ozone depletion over Antarctica during the springtime does not affect the UV-B measurements. The agreement between UV-B measurements and calculations for clear sky days at solar noon is better than 10% for zenith angles <70º. A simple model to calculate total radiation was obtained by fitting the experimental values under clear sky conditions. The agreement is better than 5% for zenith angles <70º. The small interannual variability
