Timeseries of carbonaceous aerosol emissions (BC + POM) in Tg month⁻¹ from biomass burning sources averaged globally (grey line; same in all panels) and over several major source regions (panels). For the regional emissions, red and green shading indicates the relative contribution of BC and POM, respectively, to the total carbonaceous aerosol emissions; the total carbonaceous aerosol emissions are the sum of the POM and BC contributions (i.e. stacked area plots are shown, but POM emissions far exceed BC emissions). Comparing the regional and global timeseries, we show regional emissions events of global importance, such as the 1997 Indonesian fires.
