Fig. 4: Response of organic aerosol (OA) on precursor reductions.
From: Widespread 2013-2020 decreases and reduction challenges of organic aerosol in China
Cutting all OA precursors in each sector represent model scenarios of clean-energy transition. Cutting individual category of OA precursors in each sector represent model scenarios of end-of-pipe control. OA concentrations are population-weighted annual mean concentrations. Percent values represent the reductions relative to the 2019 concentrations.
