N2 - Ozone plays a key role in the photochemical equilibrium of the atmosphere. In the stratosphere, it absorbs harmful ultraviolet solar radiation, in the troposphere it is one of the main air pollutant, greenhouse gases and it is involved in the troposphere’s oxidative capacity. In this study, we analyze the ozone variability in different atmospheric layers over St. Petersburg (Russia) measured with the ground-based FTIR spectrometer Bruker 125 HR at the Peterhof station (59.82 N, 29.88 E), and compare it to the satellite Infrared Atmospheric Sounding Interferometer (IASI) ozone retrievals. The FTIR spectrometer has a maximum optical path difference of 180 cm, yielding an apodized spectral resolution of 0.008 cm-1, and has been recording IR spectra since 2009. The high spectral resolution of the registered spectra allows the retrieval of the ozone content in four atmospheric layers. We applied the PROFFIT inversion code to the ozone vertical profiles retrievals in 9.6-m O3 absorption band and calculated the dail
