Paper Abstract

Satellite-based remote sensing to measure the chemical composition of the atmosphere has been under three different viewing geometries: nadir, occultation, and limb viewing. In the occultation mode, the sun, the moon, or the star has been selected as a target to trace it as soon as it comes above the horizon and until the line of sight reaches a maximum tangent height. Traditionally, these instruments of remote sensing observe reflected, backscattering, transmitted radiation of atmosphere, or natural thermal emission of the surface and atmosphere. And the spectra of the atmosphere from ultraviolet, visible, infrared to microwave can be detected by the spectrometer. Recently, a new technique was experimented to combine the limb viewing mode and scattering of the atmosphere, which is called as the limb scattering measurement. Based on the comparison of different observation techniques for the atmospheric chemistry, the limb scattering technique is illustrated here. And the optical characteristics of this technique are analyzed. The instruments employing this technique, including OSIRIS (the Optical Spectrograph and Infrared Imager System) onboard the Odin satellite launched in February 2001, SCIAMACHY (the SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY) onboard the Envisat satellite launched in March 2002, and SOLSE (the Shuttle Ozone Limb Sounding Experiment) on Hitchhiker Junior (HH-J) in 2003, are taken as examples for describing application of the technique respectively.
