Overview of surface ozone variability in east Asia-North Pacific region during IGAC/APARe(1994—1996)

Journal of environmental Sciences 2004年第4期16卷 599-609页

Shim environmental engineering Unit Department of Civil and Structural Engineering The Hong Kong Polytechnic University Hong Kong Department of Atmospheric Science Nanjing University Nanjing 210093 China Chinese Academy of Meteorological Science Beijing 100081 China Research Center for Advanced Science and Technology University of Tokyo Tokyo Japan Department of Atmospheric Science "National" Taiwan University Taipei Taiwan China Global environmental Research Center Korea Institute of Science and Technology Seoul South Korea

Surface ozone(O\-3) was measured at Oki Island(Japan), Cheju Island(South Korea), Lanyu Island(Taiwan Province, China), Cape D'Aguilar(Hong Kong SAR) and Lin'an, Longfenshan, Waliguan(China mainland) during January 1994—December 1996 as a component of IGAC/APARe(International Global Atmospheric Chemistry/east Asia-North Pacific Regional experiment). This paper gave a joint discussion on the observational results at these stations over the study region. Investigations showed that the average of surface O 3 mixing ratios at the seven sites are 47.9±15.8, 48.1±17.9, 30.2±16.4, 31.6±17.5, 36.3±17.5, 34.8±11.5 and 48.2±9.5 ppbv, respectively. Significant diurnal variations of surface O 3 have been observed at Oki, Cheju, D’Aguilar, Lin'an and Longfenshan. Their annual averaged diurnal differences range from 8 to 23 ppbv and differ in each season. Surface O 3 at Lanyu and Waliguan do not show strong diurnal variability. Seasonal cycles of surface O 3 showed difference at the temperate and the subtropical remote sites. Oki has a summer minimum-spring maximum, while Lanyu has a summer minimum-autumn maximum. The suburban sites at D'Aguilar and Lin'an report high-level O 3 in autumn and low level O 3 in summer. Surface O 3 remains high in autumn and low in winter at the rural site Longfenshan. For the global background station Waliguan, surface O 3 exhibits a broad spring-summer maximum and autumn-winter minimum. The backward air trajectories to these sites have shown different pathways of long-range transport of air pollution from east Asia Continent to North Pacific Ocean. Surface O 3 was found to be strongly and positively correlated with CO at Oki and Lanyu, especially in spring and autumn, reflecting the substantial photochemical buildup of O\-3 on a regional scale. It is believed that the regional sources of pollution in east Asia have enhanced the average surface O 3 concentrations in the background atmosphere of North Pacific.
