                         the events of influence of the Antarctic Ozone Hole (BOA) that 
                         occurred over the South of Brazil in 2016. To reach this goal, 
                         days of reduction were used in the stratospheric ozone content 
                         based on Total Ozone Column (CTO) daily average data obtained from 
                         the Brewer spectrophotometer installed at the Southern Space 
                         Observatory (OES/INPE) (29.443752 ºS, 53.823084 ºW; 488.7 meters) 
                         and by the Ozone measuring instrument (Ozone Monitoring Instrument 
                         - OMI) onboard the NASA Aura satellite. For those days, 
                         stratosphere dynamics analyses were carried out through isentropic 
                         fields of Potential Vorticity (PV) at 600 and 700 K (Kelvin) 
                         levels of potential temperature, using the daily PV averages 
                         obtained from ERAInterim reanalysis of ECMWF (European Center for 
                         Medium-range Weather Forecast) to verify the origin of the 
                         ozone-poor air masses. Thus, the confirmation of the origin of 
                         these masses through the retroactive trajectories obtained using 
                         the HYSPLIT model (Hybrid Single-Particle Lagrangian Integrated 
                         Trajectory) of NOAA (National Oceanic and Atmospheric 
                         Administration). In addition, images of the ozone content of the 
                         OMI satellite were used as a complementary technique to verify the 
                         performance of BOA over Southern Brazil. Then, 6 events of 
                         influence of the Antarctic Ozone Hole were identified over the 
                         South of Brazil in 2016, with an average reduction percentage of 
                         11% of the CTO to monthly climatologies, confirmed by the passage 
                         of stratospheric polar filaments over the OES region, observed in 
                         the VP isentropic fields at the 600 and 700 K potential 
                         temperature levels as well as by the retroactive trajectories of 
                         polar origin obtained in the HYSPLIT model.",
