Fig. 2: Changes in effective radiative forcing (ERF) due to changes in anthropogenic emissions of aerosols and precursors.

Spatial distributions of changes in annual mean ERF (W m−2) due to changes in (a) global, (b) China’s domestic and (c) foreign anthropogenic emissions of aerosols and precursors in 2019 relative to 2013. Changes in ERF are calculated as the differences in net radiative fluxes at the top of the atmosphere. The shaded areas indicate results are statistically significant at the 90% confidence level. Regional averages of the changes over China (CN), North America (NA) and Europe (EU) are noted near these regions.
