Abstract

Product data from DOMINO version 2.0 for January 2005 to December 2013 was used to analyze the temporal and spatial variation for vertical column density of tropospheric NO2 （TroNO2） over the Yangtze River Delta of China. Results showed that （1） the mean annual TroNO2 vertical column density was 9.72 1015 moleccm－2, the compound growth rate was 2.10%, and growth was 2.6 1014 moleccm－2. （2） Concentration of the TroNO2 column over 9 years indicated a maximum concentration in winter, followed by autumn, spring, and summer. （3） Primarily human activity but also climate influenced the TroNO2 column concentration. （4） The TroNO2 column concentration in northern Jiangsu and the central parts of southwest Zhejiang steadily increased over nine years; whereas it remained stable in southern Jiangsu and northeast Zhejiang. Thus, even with abnormally low temperatures and an arid climate contributing to the apparent increase in the Yangtze River Delta, the TroNO2 column concentration seemed acceptable for domestic economic development. ［Ch, 4 fig. ３ tab. 43 ref.］
