Abstract

We present the results of a study to determine the effect atmospheric properties have on the retrieval of temperature profiles. A high spectral resolution line-by-line atmospheric radiative transfer code, Emission Spectra, is used to compute radiances for different atmospheric conditions. Given the radiance due to variations in aerosols, observation angles, initial conditions, and spectral noise, we retrieve atmospheric temperature profiles using a Backus- Gilbert constrained eigenvalue approach. Limitations of using a constrained eigenvalue approach are discussed. Analysis of the eigenvalues provides valuable insight into the operation of this algorithm and may yield information to refine this methodology.
