2001年3月7日和8日，利用电化学浓差电池臭氧探测仪在香港和昆明上空观测到对流层低层臭氧增强。利用NCEP资料、大气臭氧总量资料、MM 5数值模拟资料、TOMS的AI资料、MODIS的气溶胶光学厚度资料和MOPITT的CO浓度资料，分析了东南亚生物质燃烧对香港和昆明对流层低层臭氧分布的影响。生物质燃烧排放的输送表明，香港和昆明上空对流层低层臭氧的增强来自东南亚发生大规模火灾的区域。TOMS AI图像和大气背景环流显示，东南亚地区的生物质燃烧羽流可以被输送到中国西南/南部的下风向，导致对流层低层臭氧浓度的增加。
Ozone enhancement was observed in the lower troposphere over Hong Kong and Kunming on 7 and 8 March 2001 using the electrochemical concentration cell ozonesondes. Based on the data of NCEP, total column ozone, numerical simulation of MM5, AI from TOMS, aerosol optical depths from MODIS, and CO concentration from MOPITT, the influence of biomass burning in Southeast Asia on the ozone distribution in the lower troposphere over Hong Kong and Kunming is analyzed. The transport of the emissions of biomass burning shows that the enhancement of the lower tropospheric ozone over Hong Kong and Kunming is from the region where large-scale fires occurred in Southeast Asia. TOMS AI images and the atmospheric background circulations reveal that the biomass burning plumes in Southeast Asia can be transported to downwind South/Southwest China and lead to enhancement of the ozone concentration in the lower troposphere.
