Paper Abstract

In the early 1980s, the SO2 pollution sources in Chengdu were related to coal consumption. One-third of total annual coal consumption in Chengdu came from Chengdu Coal-fired Power Plant, the largest coal-fired unit. On the basis of the monitoring result of sampling by aircraft over Chengdu in the May of 1984 and the September of 1989, it is found that the distribution of the concentration of SO2 in the upper level of atmospheric boundary layer (ABL) is relevant to the elevated pollution sources of Chengdu Coal-Fired Power Plant and local meteorological condition. However, the concentration of SO2 is normally about 10 ppb from the top of ABL up to an altitude of 4000 m and does not change obviously with the increase of altitude. This may be relevant to the peculiar geographical position and climatological condition of Chengdu.
