Statistical analysis of ozone in 1999-2001

Spectral analysis is used to investigate the stratospheric ozone formation and decomposition processes. To detect the reason for extreme high ozone concentrations for each season, the data was converting into high-frequency seasonal component; the latter has been evaluated by using the ozone concentrations at this location. In the data set of 1999-2001 this influence contributed peak at cycle duration of 2, 40, and 300 day peaks in the power density spectrum estimated from the ozone data.
