2002年3月，作为一项国际合作研究工作，首次对大陆中国上空的大气污染物进行了空中观测。渤海上空的观测航班从大连飞往丹东、锦州和青岛。观测到高浓度的气态污染物(臭氧、二氧化硫和氮氧化物)，二氧化硫和氮氧化物具有很好的相关性。颗粒污染物的化学成分对比表明，细颗粒物中硫酸盐离子浓度较高。硫酸盐和硝酸盐离子的浓度与铵离子和钙离子的浓度具有良好的相关性，表明渤海地区的气溶胶被很好地中和了。
The first aerial observations of atmospheric pollutants over mainland China were performed as an international collaborative research effort in March, 2002. Observation flights over Bo Hai were made from Dalian to Dandong, Jinzhou, and Qingdao. High concentrations of gaseous pollutants (O3, SO2, and NOx) were observed; SO2and NOxshowed a very good correlation. Comparing the chemical compositions of particulate pollutants showed that there was a high concentration of sulfate ions in fine particles. Concentrations of sulfate and nitrate ions showed good correlations with concentrations of both ammonium and calcium ions, suggesting that the aerosols over the Bo Hai area were well neutralized.
