中文摘要：

基于光化学模型模拟氧红外大气（OIRA）波段1.27μm气辉体发射率（VER）,是利用临边OIRA波段卫星数据反演中间层臭氧浓度一个重要的过程。从奇氧族光化学反应出发,基于大气动力学和光化学理论,建立了O2（a1Δg）的光化学模型。通过太阳辐射模拟值,解算了光化学反应系数,进而进行了Odin卫星轨道面内气辉VER的模拟。结果表明,白天气辉VER一般数量级达到106,峰值出现在50~55 km高度范围,而黑夜VER几乎为0。且随天顶角增大,VER达到峰值的高度增大。与利用OdinOSIRIS IR Level1数据反演的同时间VER剖面相比,VER剖面在数值量级、二维结构特征和衰减变化时间点方面,有很高的一致性。而且高纬地区比低纬地区一致性高,特别是80~100km之间稳合度最高,证明使用建立的光化学模型能够反演高纬度地区中间层臭氧。

英文摘要：

Simulation on 1.27 μm airglow volume emission rate（VER） is an indispensable aspect for inversion of mesospheric ozone concentration from satellite measurement in the near oxygen infrared atmospheric（OIRA） band.In this study,the photochemical reactions of odd oxygen family were reviewed.A photochemical model of O2（a1Δg） was established based on the atmospheric kinetics and photochemistry.The photochemical index were solved from the modeled solar fluxes,and then the airglow VER in an orbit plane of Odin was simulated.The results show that the large 106 of VER emerges in the daytime,with a peak near 50-55 km.The VER in the nighttime is nearly zero.The VER peak rises with the increase of solar zenith angle.The comparison between the modeled and retrieved VER from Odin OSIRIS IR Level1 data indicates that,there is a good agreement among the scale,photochemical features and decay time at all points along the section.Furthermore,the difference between the modeled and retrieved VER is smaller in high latitudes and the minimum is achieved between 80 and 100 km.It is shown the photochemical mode is able to study mesospheric ozone retrieval there.
