Abstract: 根据TOR卫星数据分析,我国长江三角洲地区对流层O2柱含量的长期变化就全年和大多数月份而言均为增长趋势,1978-2000年间其年均值的增长趋势为0.82 DU/10 a。这种长期变化趋势所引起的气候效应及其对大气氧化性的影响值得进一步研究。结果表明,长江三角洲地区对流层O3柱含量的季节变化与该地区的临安区域大气本底站的地面O3季节变化有着显著的相关关系,临安站的观测数据具有区域代表性。
Analysis of tropospheric ozone residue(TOR)data from satellite measurements indicates an increasing trend of tropospheric ozone over the Yangtze Delta region of China.The increasing trend can be derived both from the annual mean TOR and from the monthly mean TOR except for March.During the period of 1978-2000,the increase in the annual mean TOR was 0.82 DU per decade.The study on impact of this long-term trend on the climate and atmospheric oxidizing capacity over the region should be done.Data comparison shows a significant correlation between the TOR and surface ozone data collected at the GAW Lin’an regional background station in the Yangtze Delta region,suggesting that the observational data have regional representativeness
