Abstract

The Limb-Atmospheric Infrared Spectrometer (LAS) was launched on February 14, 1984, boarding on the satellite "OHZORA" (EXOS-C) to investigate the constituents of the middle atmosphere. This sensor measures the infrared spectra of the solar radiation passing a limb atmosphere at various tangent heights. These spectra include the "whole" absorption bands of water vapor, carbon dioxide, methane, ozone, and nitrous oxide. Furthermore the spectra give the wavelength dependence of the aerosol scattering extinction. Consequently, we can get the vertical profiles of these atmospheric constituents at various global points, with good accuracy.
