First NO2 measurements by car-DOAS instrument in Minsk
Abstract
The work is dedicated to the car-DOAS instrument that has been developed in Research Institute of Applied Physical Problems, BSU and its application for NO2 vertical column retrieval. The instrument is based on own production spectrometer with concave holographic diffraction grating and non-cooled CCD-array detector. The instrument is employing in spectral range of 340 - 600 nm and FWHM = 4.5 nm. The optical fiber radiation input system with zenith geometry has been implemented. The comparison results with reference instrument will be presented and discussed. Reference instrument successfully took part in MAD-CAT (2013) and CINDI-2 (2016) international inter-comparison campaigns. It has spectral range of 320 - 400 nm and FWHM = 0.32 nm. First mobile measurements around the Minsk aiming to retrieve NO2 emission power of the city have been carried out. Obtained results have been compared with Belarusian Hydro-meteorological Centre data and satellite data; corresponding results will be presented and discussed.
