The University of Saskatchewan (USask) routinely derives stratospheric aerosol extinction from limb radiance measurements by the Ozone Mapping and Profiler Suite Limb Profile (OMPS-LP). Recently a new version of the data product (v2.1) has been publicly released with several improvements. Most notably aerosol extinction is reported at multiple wavelengths using a novel bias correction scheme that reduces wavelength dependent errors present in limb scatter derived aerosol by training a gradient boost regression scheme on coincidences with SAGE III-ISS occultation measurements. The algorithm has also been extended to routinely process data from both the NPP (launched in 2011) and N21 (launched in 2021) versions of OMPS-LP. Here we describe the algorithm, it's improvements, and validate the data product against correlative measurements.
