基于OMI数据分析青藏高原周边对流层低层臭氧的分布特征

Seasonal variation of atmospheric ozone in the lower tropospheresurrounding the Tibetan Plateau based on OMI satellite date

  • 摘要: 提出一种利用地形海拔落差以及臭氧总量差来估算对流层低层大气臭氧浓度的方法.根据搭载于美国宇航局Aura卫星上的臭氧监测仪(OMI)提供的臭氧总量日观测数据,利用该方法计算出青藏高原与其周边地区四川盆地及印度北部的地形海拔落差及臭氧总量差,进一步分析了该地区低层大气臭氧的分布特征.结果表明:青藏高原周边地区对流层低层大气臭氧分布呈明显的季节变化,且低层大气臭氧分布有南北差异,南部臭氧含量高于北部.

     

    Abstract: In this work,contrasting of total ozone over different terrain elevation is used to estimate the atmospheric ozone in the lower troposphere.Daily time series of total column ozone measured by the Ozone Monitoring Instrument (OMI) onboard the NASAs Aura satellite are used here.This method is applied to study the seasonal variation of atmospheric ozone over the Sichuan Basin and Northern India by topographic contrast to Tibetan Plateau.The analyses show that there is an evident seasonal variation of atmospheric ozone in the lower troposphere surrounding the Tibetan Plateau.It is worth noting that there also is a difference among the north and south parts in this area,with higher ozone concentration in the south part.
