Abstract:Monitoring the concentration and distribution of nitrogen dioxide NO2 in urban environment is of great interest because of the importance of this gaseous pollutant in affecting air quality. In this paper we present the development of a multi-axis differential optical absorption spectroscopy instrument capable of sensitively detecting NO2. The passive instrument collects the sun light scattered by the air molecules and aerosols in the atmosphere and measures the spectrum using a highly sensitive portable spectr… Show more
