Substantial reductions in black carbon from both fossil fuels and biomass burning during China’s Clean Air Action Open
Black carbon (BC) aerosols exacerbate air pollution and climate warming, but their climatic impacts and sources are poorly constrained by bottom–up emission inventories (EIs). China’s Clean Air Action (CAA), which was launched in 2013, pro…
