dc.description.abstractWe examine seasonal and geographical distributions of tropospheric ozone production and mixing ratios over East Asia with a global three-dimensional chemical transport model called Model of Ozone and Related Tracers, version 1 (MOZART 1). Net ozone production within the East Asian boundary layer exhibits three distinct seasonal cycles depending on region (north of 20 degrees N, 5-20 degrees N and south of 5 degrees N). North of 20 degrees N, net ozone production over East Asia from spring through autumn is found to have a maximum extending from 25 degrees N-40 degrees N and from central eastern China to Japan, resulting from the strong emission and transport of anthropogenic O-3 precursors. In winter, maximum O-3 production in this region occurs between 20 degrees N and 30 degrees N, This is a region of long-range transport. Over the Indochina peninsula, between 5 degrees N and 20 degrees N, net O-3 production is controlled by the seasonal cycle between wet and dry seasons and has a maximum at the end of the dry season due to emissions from biomass burning. South of 5 degrees N, in the true tropics, O-3 mixing ratios are relatively constant throughout the year and do not exhibit a seasonal cycle. A spring-summer maximum of net O-3 production is found throughout the troposphere in East Asia. We estimate an annual net O-3 production in East Asia of 117 Tg/yr, Both model results and analysis of measurements of O-3/CO correlations over East Asia and Japan show strong variability as a function of both photochemical activity and seasonal meteorology, and indicate ozone export off the coast of East Asia in spring. An upper estimate of O-3 export from East Asia to the Pacific Ocean in the mid-1980s of 3.3 Gmol/d (58 Tg/yr) is obtained.en_US
