GIS-Based Analysis of NO2 Concentrations in Changchun City
Investigated the monitored data of NO2 in July 2002-2005 to gain a better understanding of NO2 distribution in summer of Changchun, which is located in Northeast China. The dynamic information of NO2 concentrations and the relationship between Nox and O3 were studied. Particular attention was paid to the distribution of NO2 concentrations in July 2004. By visualizing the monitored data of 2004, we found that NO2 played an important role in the overall air quality evaluation. By using GIS, new relationships and correlations were established and spatial distribution of air pollutants was more readily evaluated and quantified in this paper.
