We examined the characteristics of ozone and temperature data over the tropical station Costa Rica during the period
of 2012 – 2017, downloaded from Southern Hemisphere ADditional OZonsondes (SHADOZ) site. Our analysis reveals
important variations of ozone and temperature structures in troposphere and stratosphere. An interannual variability of ozone
fluctuations was observed in the measured wave activity and seasonal variation has also been observed with higher value in
Summer Season (June July August). Vertical profiles of ozone and temperature have been used to examine the characteristics of
wave number spectra of their fluctuations thereby assess the possible roles of gravity wave activity and to determine dominant
vertical wavelengths of ozone spectra. Average slopes of wave number spectra are found to be –2.76 (–2.46) in the troposphere
and –2.53 (–2.61) in the lower stratosphere for ozone (temperature) in summer.
