Questions about how emissions are changing during the COVID-19 lockdown periods cannot be answered by observations of atmospheric trace gas concentrations alone, in part due to simultaneous changes transport, emissions, dynamics, photochemistry, and chemical feedback. A transport model simulation benefiting from a multi-species inversion framework using well-characterized should differentiate those influences enabling closely examine emissions. Accordingly, we jointly constrain NO x VOC TROPOspheric Monitoring Instrument (TROPOMI) HCHO NO2 columns months March, April, May 2020 (lockdown) 2019 (baseline).
