Abstract:

Based on the atmospheric pollutants data from a differential optical absorption spectroscopy (DOAS) system in Nanjing University of Information Science and Technology, the mass concentrations of O3, NO2 and SO2 in the northern suburb of Nanjing from January to November in 2008 were analyzed. The results indicate that the monthly mean mass concentrations of O3 are high in summer, while both mass concentrations of NO2 and SO2 are low in summer. The diurnal variation curve of O3 mass concentrations is mono-modal, while both curves of NO2 and SO2 mass concentrations are bimodal. The correlation between diurnal NO2 and O3 mass concentrations is negative. The SO2 mass concentrations are generally high in this region, and the weekend effect is more apparent for NO2 and SO2thanfor O3 in summer.
