利用曙暮气晖反演中层臭氧的可行性

FEASIBILITY OF RETRIEVING MESOSPHERIC OZ0NE FROM TWILIGHT AIRGLOW

利用1.27μm曙暮气晖反演大气O3是中间层03含量的重要测量方法．本文研究了1.27μm地面曙暮气晖所包含的独立信息参量、可测量高度和垂直分辨率；讨论了光化学参量、大气参量不定性的影响和对中间层O3含量变化的灵敏度．结果指出，利用这一方法可以给出60－90km高度的大气O3含量，光化模式参量不定性的影响约为10％．

Rerieving atmospheric ozone using 1.27μm twilight airglow is an important method of mesospheric atmospheric ozone measurements. In this paper, the information content,measurable height and venical resolution have been studied, and the effect of the uncertainty of photocheemical and atmospheric models parameters and the sensitivity of the variation in mesospheric ozone content have been discussed. The numerical simulation results show that the atmospheric ozone content in 60-9Okm altitude may be given using 1.27μm twilight airglow measurements, the effect of the uncertainty of photochemical model parameters is about 1O%.
