基于SABER卫星数据的临近空间大气参量分析

Analysis on near space atmosphere parameters based on SABER satellite data

临近空间大气中存在复杂的光化学、动力学和电动力学过程,直接影响航天器的准确入轨和安全运行,近年来已成为国际研究新热点。文章概述了临近空间大气环境特征,介绍了TIMED卫星和探测技术,基于最新的SABER/TIMED v2.0Level 2A数据获取大气温度、大气压、大气密度和臭氧含量等一系列参量,对其特性进行讨论并结合实例进行量化分析。

Near space has become an international research hotspot in recent years,where exist complex photochemistry,kinetics and electrodynamics process which can affect the accurate injection and secure operation of spacecraft.This paper introduces the characteristics of near space atmosphere environment as well as TIMED satellite and its sounding technology.Based on the newest data from SABER/TIMED v2.0Level2A,a series of parameters such as air temperature,air pressure,air density and ozone content are obtained.Then,its characteristics are discussed and quantitative analyzed combining with typical cases.
