Uncertain Model Parameters for SCIAMACHY Limb Retrieval

In this presentation we describe two techniques for treating the uncertain model parameters for the SCIAMACHY limb retrieval processor. As uncertain parameters we consider the tangent height and the surface albedo. The first technique consists in a simultaneous estimation of the uncertain parameters and the target parameters, while the second technique is based on a generalized covariance matrix including all information on spectral sensitivity of the measured signal to the uncertain parameters.
