Zheng, YG, Zhu, PJ, Chan, CY, Chan, LY, Cui, H, Zheng, XD, Zhao, Q, Qin, Y (2004). Influence of biomass burning in Southeast Asia on the lower tropospheric ozone distribution over South China. CHINESE JOURNAL OF GEOPHYSICS-CHINESE EDITION, 47(5), 767-775.

Abstract
Ozone enhancement was observed in the lower troposphere over Hong Kong and Kunming on March 7 and 8, 2001 using the electrochemical concentration cell ozonesondes. Based on the data of NCEP, Total Column Ozone, the numerical simulation of MM5, AI from TOMS, aerosol optical depths from MODIS, and CO concentrations from MOPITT, we analyze the influence of the biomass burning in Southeast Asia on the ozone distribution in the lower troposphere over Hong Kong and Kunming. The transport of the emissions of biomass burning shows that the enhancement of ozone in the lower troposphere 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 are transported to downwind South China and lead to enhancement of the ozone concentrations in the lower troposphere.
