At the end of October, 2019, I attended the science team meeting for the SAGE III instrument, currently in orbit on the International Space Station. My presentation, about using the NO2 data from SAGE III, as well as that from its precursor SAGE II and another instrument called OSIRIS, to study long term trends, is now publicly available. You can check it out by clicking on the science team tab at this link and then clicking on “Trends and Variability in Stratospheric NO2 from Merged SAGE II and OSIRIS Satellite Observations“.
