Abstract

Aiming at the requirement of accurate simulation of near-space atmospheric infrared background radiation, this paper simulates near-space infrared atmospheric background radiance according to atmospheric parameters detected by satellites. The multi-channel infrared radiometer SABER (Sound of the Atmosphere using Broadband Emission Radiometry) carried by TIMED satellite (Thermosphere, Ionosphere Mesosphere Energetics and Dynamics) is used to acquire atmospheric profile. Combined with limb observation model and atmospheric background radiance calculation model, the transmittance and spectral radiance of infrared atmospheric background were simulated. The spectral radiance of atmospheric background under the standard atmospheric model and satellite atmospheric profiles was compared to analyze the difference between the two atmospheric parameter. In the infrared band, the atmospheric profile has a great impact on atmospheric background radiance. For the accurate simulation calculation of infrared background spectral radiance in different regions, the influence of atmospheric profile parameters should be taken into account.
基于卫星观测数据的翼面观测红外背景光谱辐射度分析
针对近空间大气红外背景辐射精确模拟的要求,根据卫星探测到的大气参数,模拟近空间红外大气背景辐射。利用TIMED卫星搭载的多通道红外辐射计SABER (Sound of Atmosphere using Broadband Emission Radiometry)(热层、电离层、中间层能量学与动力学)获取大气剖面。结合翼缘观测模型和大气背景辐亮度计算模型,对红外大气背景的透射率和光谱辐亮度进行了模拟。比较了标准大气模式和卫星大气廓线下大气背景的光谱辐亮度,分析了这两个大气参数的差异。在红外波段,大气剖面对大气背景辐射有很大的影响。为了准确模拟计算不同区域的红外背景光谱辐射,需要考虑大气廓线参数的影响。
