中文摘要：
探索了如何从空间对远紫外日辉辐射进行遥感观测,以便为检测高层大气状态提供新的监测方法。针对风云三号（FY-3）气象卫星有效载荷观测结果的数据处理,研究了利用140～180nm波段的LBH（Lyman-Birge-Hopfield）日辉辐射与OI 135.6nm日辉辐射进行O/N2反演的方法。通过研究这两个远紫外日辉观测信号的辐射特性,验证了二者的柱辐射率之比135.6/LBH与太阳活动呈相关关系。检验了太阳活动对O/N2反演曲线的影响,结果表明：太阳活动的变化会造成O/N2反演曲线之间存在比较大的偏差,因此在O/N2的反演技术中必须考虑如何消除太阳活动的影响。本文的工作为FY-3载荷仪器的O/N2图像反演技术的研究奠定了基础。
英文摘要：
How to obverse the far ultraviolet（FUV）dayglow emission from space in remote sensing was explored to provide a method for monitoring of the upper atmosphere.On the basis of data processing for observation signals of payloads on the meteorological satellite FY-3,an O/N2retrieval method by use of the Lyman-Birge-Hopfield（LBH）band in the range of 140-180nm and the OI 135.6nm dayglow emissions was researched.By analysis of the characteristics of 140-180nm and the OI 135.6nm dayglow emissions,it proves that the 135.6/LBH is correlated with solar activity. Then,the effects of the solar activity on the O/N2retrieval curves were investigated,and the resultsshow that there are large deviations between the retrieval curves with different solar activities,so the solar activity effect must be removed in the O/N2retrieval method.This work provides a solid basis for the development of the O/N2retrieval method prepared for data processing of instruments on FY-3.
