                         measure ozone and meteorological profiles have been made at the 
                         Southern Space Observatory, Brazil (29.4S, 53.8W) since 1996. In 
                         this work, a total of 50 launchings between November 1996 and 
                         December 2000 are analysed. All of them achieved at least the 
                         tropopause level, which local average altitude is around 17.5 km. 
                         Around 54 % of the soundings show a secondary ozone peak in the 
                         troposphere. The secondary ozone peak average altitude is 3,362 m, 
                         but the peaks occurrence spreads over the range 0.9 - 6.1 km. The 
                         ozone partial pressure average in this altitude range is 19.5  
                         3.5 \μ hPa without the peaks, while the peaks only have an 
                         average of the 38.8  10.6 \μ hPa. The peaks seasonal 
                         distribution is uneven, with occurrences mainly in November, with 
                         10 events, and December, with 7 events, meaning 91 % and 70 % of 
                         the monthly soundings, respectively. Both these months and January 
                         are the months with maximum biomass burning in the region of the 
                         Rio Grande do Sul State for the same period (1996 -- 2000) 
                         according to NOAA-12 satellite data. These could indicate that the 
                         sources of the secondary peak are due to biomass burning events.",
