      摘要: 根據TOR衛星數據分析,我國長(cháng)江三角洲地區對流層O3柱含量的長(cháng)期變化就全年和大多數月份而言均為增長(cháng)趨勢,1978-2000年間其年均值的增長(cháng)趨勢為0.82 DU/10 a。這種長(cháng)期變化趨勢所引起的氣候效應及其對大氣氧化性的影響值得進(jìn)一步研究。結果表明,長(cháng)江三角洲地區對流層O3柱含量的季節變化與該地區的臨安區域大氣本底站的地面O3季節變化有著(zhù)顯著(zhù)的相關(guān)關(guān)系,臨安站的觀(guān)測數據具有區域代表性。

      Abstract: 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誥n regional background station in the Yangtze Delta region, suggesting that the observational data have regional representativeness.

      Key words: tropospheric ozone, long-term trend, the Yangtze Delta
