The study of total ozone columns above Kiev and variations of ozoneconcentrations in the troposphere at different altitudes above Kiev was carriedout using ground-based Fourier Transform InfraRed (FTIR) spectrometricobservations that are taken on a routine basis at the Main AstronomicalObservatory of the National Academy of Sciences of Ukraine (MAO NASU). Thisstudy was performed within the framework of the international ESA-NIVR-KNMIOMI-AO project no.2907 entitled OMI validation by ground-based remote sensing:ozone columns and atmospheric profiles during the time frame 2005-2008. Theinfrared FTIR spectral observations of direct solar radiation in the wavelengthrange of 2-12 micron as transmitted through the Earth's atmosphere wereperformed during the months of April-October of each year. The aim of theproject was the validation of total ozone columns and vertical ozone profilesas obtained by the Ozone Monitoring Instrument (OMI)) onboard of the NASAEOS-Aura scientific satellite platform. The modeling of the ozone spectral bandshape near 9.6 microns was performing with the MODTRAN code and a molecularband model based on the HITRAN-2004 molecular database. The a-prioriinformation for the spectral modeling consisted of water vapor and temperatureprofiles from the NASA EOS-Aqua-AIRS satellite instrument, stratospheric ozoneprofiles from the NASA EOS-Aura-MLS satellite instrument, TEMIS-KNMIclimatological ozone profiles and surface ozone concentration measurementsperformed at the specific times of infrared spectra observations. Thetroposphere ozone variability was analyzed for two typical episodes: the springepisode of enhanced total ozone columns and the summer episode of enhancedsurface ozone concentrations.
