Ozone columns obtained by ground‐based remote sensing in Kiev for Aura Ozone Measuring Instrument validation

Abstract

[1] Ground-based observations with a Fourier transform spectrometer in the infrared region (FTIR)

The study of ground-level ozone over Kyiv and its impact on public health

“…They include ozone data for the lower layer of the atmosphere beginning in 2005. We performed a comparison of these ozone profiles for Kiev and the profiles recovered by us from the infrared Fourier spectrometer observations and modelling with MODTRAN4 code [7,8,9]. The first comparison of our retrieved profile for April 23, 2007 with OMO3PR data showed a significant difference in tropospheric part of the profiles (Fig.…”

“…Simulation of ground-level ozone concentrations in Kiev for an episode of its high concentration in August 2000 [3,10,11] is performed using a model of urban air pollution UAM-V [12]. Aa study of total ozone over Kiev and its concentration changes with altitude in the troposphere was also carried out using ground-based observations with the infrared Fourier spectrometer at the Main Astronomical Observatory of the National Academy of Sciences of Ukraine (MAO NASU) as a part of the ESA-NIVR-KNMI project no 2907 "OMI validation by ground based remote sensing: ozone columns and atmospheric profiles (2005)(2006)(2007)(2008))" [7,8,9].…”

Total columns and vertical profiles of ozone above Kyiv in 2005‒2008

“…Ground-based observations of strong and weak absorption lines in the electromagnetic spectrum of direct solar radiation transmitted through the Earth's atmosphere to the surface are routinely made at the Main Astronomical Observatory of National Academy of Sciences Ukraine with the Fourier Transform InfraRed spectrometer (FTIR model Infralum FT 801, [Egevskaya, Vlasov, Bublikov, 2001]). This particular instrument was optically redesigned for the study of atmosphere pollution in the Kiev metropolitan area [Shavrina et al, 2007]. The working spectral range of the Fourier spectrometer is 2-12 microns (equivalent to 800-5000 cm −1 with a best spectral resolution of˜1.0cm −1 .…”

“…For the analysis of our observations of 2007-2008, we used MLS data version v2.2, the higher accuracy of which has enabled us to develop a new method of ozone profile analysis: we are now varying the input profile of the tropospheric ozone only, where we only scale the stratospheric profile by a certain factor within the specified accuracy of MLS (2-5% in the layers of the pressure 216-0.02 hPa) without modifying its overall shape. A detailed description of our method for determining detailed tropospheric and stratospheric concentrations of ozone can be found in [Shavrina et al, 2007, Shavrina et al, 2008. The result of the analysis is the best fit of the model spectrum to the observed spectra of the ozone band, from which we obtained the best estimates of the tropospheric vertical profiles of ozone, the total column amount of ozone in the troposphere and finally the total column amount of ozone in the atmosphere.…”
