                         Space Observatory (29.4ºS, 53.8ºW) have been obtained using the 
                         MKIV (1997 2000), MKII (2000 2002) and MKIII (2002 2003) Brewer 
                         Spectrophotometers. The Total Ozone column data measured by the 
                         TOMS instruments in a grid point close to this station for the 
                         period from 1997 to 2003 are also used. The spectrophotometers 
                         measure Total Ozone Column on the wavelengths: 306.3, 310.1, 
                         313.5, 316.8 and 320.0 nm with an accuracy of about 1 percent, 
                         while TOMS measures on: 317.5 and 331.2 nm with error of about 2 
                         percent. These data are used to study the Total Ozone Column 
                         interannual variability in the Southern Brazil. The El Niño/ 
                         Southern Oscillation (ENSO) phenomenon cycle is measured by the 
                         Southern Oscillation Index (SOI). This index gives information on 
                         the phase and the intensity of the event and it is the 
                         standardized difference between the sea level pressure anomalies 
                         in Tahiti and Darwin. Monthly ozone climatological means for both 
                         equipments were calculated using the base period from January/1997 
                         to December/2003, totalizing seven years. The differences between 
                         the monthly ozone and the corresponding monthly ozone 
                         climatological mean give the monthly ozone anomalies (OA). The 
                         monthly OA for the Brewer and for the TOMS instruments show 
                         similar behaviors. In addition the linear correlations between the 
                         OA and the SOI are of 0.45 for the TOMS instruments and of 0.53 
                         for the Brewer instrument. Accordingly to a Student t-test these 
                         correlations are statistically significant. Therefore, these 
                         orrelations suggest a reduction (an increase) of Total ozone in 
                         the Southern Brazil during El Niño (La Niña) episodes.",
