Short summary
This study optimizes non-methane volatile organic compound (NMVOC) emissions in China using satellite formaldehyde data from Ozone Mapping and Profiler Suite (OMPS) and Tropospheric Monitoring Instrument (TROPOMI). By applying an advanced inversion system, we produced improved NMVOC emission inventories in 2019 and 2020. The optimized results improve formaldehyde and ozone simulations in general, and a consistency analysis is further designed to assess the reliability of these two posteriors.
