Current Capabilities in the Modeling of Infrared Limb Emission

Abstract

Accurate models of infrared limb emissions are required to interpret measured limb radiance profiles in terms of atmospheric temperatures, densities and composition. Measurements of infrared limb emission made by the Nimbus 7 LIMS experiment will be compared to calculated emission profiles based on nearly simultaneous measurements of temperature and composition. Uncertainties in spectroscopic data as well as in the in-situ measurements and how they affect the comparability will be discussed.
