Abstract

Passive remote sensing experiments that monitor the spectrally integrated limb infrared emission from various constituents in the middle atmosphere are successful only if it is possible to accurately characterize the emission from both the target species and from all other species that emit within the bandwidth of each particular radiometric channel. Accurate characterization of the measured radiances is necessary if the equation of transfer is to be inverted to yield profiles of kinetic temperature and minor constituent concentration as a function of altitude. It is, therefore, essential to have an excellent understanding of the processes that give rise to the radiative emission from each species.
