From TOMS ozone data sees the affection of Indonesia forest fire on total ozone

Biomass burning can result in tropospheric ozone increasing. In 1997, Indonesia big forest fire in dry season as a result of EWino emitted large a mount of Biomass burning plumes into the atmosphere, which produce ozone in troposphere via photochemical reaction. We mapped three day average of Earth Probe TOMS data from July to December of 1997 in Latitude of 20 degrees S to 20 degrees N, and Longitude of 30 degrees E to 180 degrees E, which involves the forest fire area. As a comparison we got every day ADEOS TOMS maps in the same area and the same period in 1996. From this maps we can fined that in October 1997 the largest total amount of ozone was about 30 dobson unit larger than the average in the same period of 1996. The area of largest amount (about 295 to 300 dobson unit) was twice appeared in September 8 to 13 and October 11 to 19 which lasted about ten days. The location of that was in the west not far from the forest fire area which can be considered as a result of seasonal wind from east to west. Besides that a fairly large amount of ozone area existed from east Indonesia through the west, we can find that ozone amount was largely increased than that of 1996.
