Abstract

Atmospheric transmittance is a significant parameter in the research of atmospheric radiation transmission. To research the impact of atmospheric profile on the simulation of infrared atmospheric transmittance, multichannel infrared radiometer SABER (Sounding of the Atmosphere using Broadband Emission Radiometry) carried by TIMED satellite (Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics) is used to acquire atmospheric profile. The infrared limb atmospheric transmittance of the South China Sea area (105°E-118°E,4°N-21°N) and MODTRAN standard atmospheric model are simulated. The differences between the two models are analyzed that in infrared spectral band, the variation of atmospheric profile has a great impact on the simulation of atmospheric transmittance. The atmospheric transmittance of the arbitrary region can be obtained by this method, which is more accurate than the standard atmospheric model.
