PENGUKURAN OZON PERMUKAAN DI BANDUNG TAHUN 2001 - 2002

The diurnal mean surface ozone concentration decreases at 6.00-6.30, and at 7.00 start to increase again. The momentarily decreased is presumed caused by increasing NOx from transportations when the sun radiation intensity still low. The maximum concentration is at 10.30 in January and 11.00 - 13.30 in July; at night the concentration are 74.43 ugr per m - 83.75 ugr per m, and in July are 89.32ugr per m-123.16ugr per m. The minimum surface ozone concentrations in January the average are 27.05 ugr per m-39.80 ugr per m, and in July are 35.64 ugr per m-58.86 ugr per m. Dago Pakar has the higher monthly means surface ozone concentration, except in October - January. In October - January surface ozone concentration is almost the samee with the other stations. The other four - stations have monthly means surface ozone concentration 2001-2002 has maximum concentration 47.09 ugr per m - 66.80 ugr per m, minimum 11.93 ugr per m - 27.27 urg per m and average 33.48 ugr per m-47.05 ugr per m. Dago Pakar and Tirtalega have higher Ozone Pollution Index. There is no specific type of surface ozone concentration distribution in wet month or dry month.
