                         ozone and UV-B radiation. The data were collected at the Southern 
                         Space Observatory (OES/CRSPE/INPE MCT), located in the southern 
                         part of Brazil, and analyzed by linear and first order exponential 
                         fits. The UV-B radiation (280315 nm) was measured by the UV-B 
                         radiometer (Eko Instruments model MS-210W) and the total ozone 
                         column was measured by the Total Ozone Mapping Spectrometer (TOMS) 
                         installed on board of NASA's Earth Probe satellite. The UV-B 
                         radiation measurements employed for correlation analysis (from 
                         July 1999 to December 2001) had fixed solar zenith angles and were 
                         taken on days with clear sky. The mathematical behavior of 
                         correlations at different angles was observed and correlation 
                         coefficients were determined by linear and first order exponential 
                         fits. High correlation coefficient values were obtained for both 
                         fits studied and the differences between them can be considered 
                         small. The values for linear fits varied from R2=0.64 (SZA 55°) to 
                         0.90 (SZA 30° and 35°) and for exponential fits varied from 
                         R2=0.63 (SZA 55°) to 0.85 (SZA 30° and 35°).",
