The remote sensing method based on ground-based measurements of the direct solar IR radiance by Bruker Fourier
spectrometer with high spectral resolution (0.005 cm-1) has been considered. The spectra measured at St. Petersburg
State University (59.88N, 29.82E) in 2009-2011 have been analyzed. The retrieval task has been processed
using SFIT2, PROFFIT and originally developed software. The ozone total column amount as well as the content in
thick atmospheric layers has been obtained for the whole period of measurements. The results have been compared
to independent ground-based and satellite measurements. The temporal variations of ozone vertical structure, such
as daily and seasonal cycles, have been studied.
