摘要
临边地球大气遥感是实现上层大气微量气体成份探测和分析的重要手段,即通过对地球大气剖面下遥感数据-特性谱线下亮温值的获取,结合相适应大气模型,通过反演获取相应气体成份的全球分布,从而为大气科学研究及全球气候变化提供科学数据及决策依据。本文从星载临边亚毫米波遥感结构建模以及地球标准大气模型出发,利用"am"综合仿真工具,给出了其特征谱线在其不同临边遥感切角下的性能仿真,从而定量分析了遥感系统综合指标。
Limb atmosphere remote sensing is a very important method to implement the detection and analysis to trace gas in upper atmosphere, which acquires the remote sense data in global atmospheric profile-brightness temperature under featured spectra, combines the corresponding atmosphere model, and obtains the global distribution of corresponding gas composition through inversion. Then it can provide scientific data and decision basis for atmospheric research and the global climatic variation. Basing on the modeling of satellite borne limb sub-millimeter wave remote sense structure and the standard earth atmospheric models, this work utilizes"am" comprehensive simulation tool to perform performance simulation of its featured spectra under different limb remote sense corner cuts, thus quantitatively analyzes the integrated index of remote sense system.
