Upcoming Improvements to the SAGE III/ISS Retrieval

The Stratospheric Aerosol and Gas Experiment operating on the International Space Station (SAGE III/ISS) is an occultation instrument that retrieves aerosol extinction and ozone, and other trace gas concentrations. Since the release of the version 5.1 data product in December 2018, the algorithm team has been exploring several modifications to improve the overall quality of the science products. This includes updates to the cross sections and how they are convolved with the SAGEIII point spread functions, improvements to the water vapor retrieval, potential new DOAS-style retrievals, and the incorporation of data from a disturbance monitoring package (DMP). These changes along with their impacts on the data products are presented.
