| Research Abstract |
Tropospheric ozone is significant for global atmospheric environment because it can damage human health and vegetation including agricultural crops. It also affects climate because is one of significant greenhouse gases. However, the ozone distribution, its budget, and therefore, its influence on the environment have not been fully understood. In this study, the influence of the biomass burning in Southeast Asia on the production of the tropospheric ozone is discussed. This study consists of three parts : (I)ozone variation observed during the BIBLE aircraft observation campaigns and influence of biomass burning in the Indonesian region, (II)ozone increased layers observed during the TRACE-P aircraft observation campaign and influence of biomass burning in the Indochina region, and (III)ozone variation over Indochina observed by an intensive ozonezonde observation and influence of biomass burning in the Indochina region.

ere quite low over the tropical Pacific Ocean. In the upper troposphere, OPG gradually increased downwind in eastern and western Indonesia. While O_3 did not increased over Indonesia, it increased by 50 % in the air masses which passed over Indonesia and were observed in Indian Ocean and northern Australia. These results indicate that ozone was produced in the air masses affected by emissions and convection over Indonesia. Average O_3 production rate during transport is estimated to be about 2ppbv/day, being comparable with the photochemical model calculation. These results demonstrate that the convection over Indonesia in association with biomass burning and lightning influenced OPG amount over Indonesia, even when biomass burning was inactive, and that it caused 10-15 ppbv (about 50 %) increase of O_3 over Indian Ocean and northern Australia.
During TRACE-P, increase of ozone and OPG was often observed at the altitude around 4 km over western and central Pacific in subtropical latitude at about 20N. Trajectory analyses and collation analyses between OPG and tracers indicate that this increase of ozone and OPG were attributed to the biomass burning in the Indochina region.
An intensive ozonesonde observation was carried out at Sri Samrong (17N, 99E), Thailand, between March and June, 2003. Observed ozone mixing ratios generally exceeded 60 ppbv and sometimes exceeded 90 ppbv throughout the troposphere. There was a stable inversion layer at an altitude around 4 km over Thailand during the observation period, indicating that ozone precursors emitted from biomass burning and industrial activities were upwardly transported up to this layer. However, ozone mixing ratios did not show significant variation above and below this layer. Meteorological analyses combined with analyses of aerosol characteristics indicated that biomass burning in Southeast Asia was not only a dominant ozone source, but also the pollutant from South Asia and the transport from the middle latitude contributed to the high ozone concentrations, even below the inversion layer.
