abstract = "Total Ozone Column data in a station in the Brazilian Southern
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.",
