Description
The SASKTRAN radiative transfer model was originally developed for operational processing of retrievals of stratospheric trace gas and aerosol from the OSIRIS limb scattered sunlight measurements. Initially designed to solve the radiative transfer equation through successive orders of scattering in a spherical atmosphere, the model has evolved to an extensive framework of modules to set the atmospheric state in multiple dimensions, specify optical properties of species, and select various methods of solution of the radiative transfer equation for various limb, nadir, and occultation measurement configurations. This talk will present details on the various options available to the SASKTRAN user, with a focus on the potential for analysis of ALTIUS measurements, including simulation of the polarized radiance, optimized two-dimensional analytic weighting functions, and efficient multiple scattering. Benchmark accuracy and computational requirement for retrievals on OSIRIS and OMPS limb scattering data will be discussed.
