SUMMARY:

Monitoring ozone using ground instruments and comparing with satellite data for mid-latitude regions is important since these regions are densely populated. The objective of the work is to identify the dominant modes of interannual variability of ozone content for the SHADOZ network station in Natal, which is a tropical region through a vertical ozone profile, for heights of 20, 25 and 29 km. 21 years of data (1998-2018) from the Southern Hemisphere Additional Ozonesondes (SHADOZ) balloon data will be used. To characterize the seasonal variability of O3 in Natal, the average values of each month and the monthly climatology will be calculated by calculating averages and respective standard deviations. And to determine the anomalies that influence this variation, the Morlet wavelet technique will be applied with data from the climatic indices Almost biennial and South Oscilation (ENSO). The interannual variability of the Natal season, on the other hand, will be obtained from the application of the wavelet analysis technique. As a result, it is expected to identify the dominant modes of interannual variability in these cities and to verify the difference between each of the localities.
