This dataset addresses the large uncertainties related to the climate impact of key climate-warming components from these emissions.\r\n\r\nThe filter-based PM2.5 samples, collected between May 2014 and April 2016,  were analysed for carbonaceous aerosols (Organic matter and black carbon), water-soluble inorganics, and carbon isotopes (\u0394\u00b9\u2074C and \u1e9f\u00b9\u00b3C) for the black carbon fraction calculations. The dual-carbon isotope signatures were used to quantify the relative contribution of black carbon to the emissions and the relative contribution of liquid fossil C4 plants and C3 plants.","url":"http:\/\/bolin.su.se\/data\/kirago-2024-fine-aerosols-1","keywords":["Atmosphere","Aerosols","Black carbon","Carbonaceous aerosol","Open fires","Carbon isotopes","Sub-Saharan Africa","Source apportionment","Earth science > Atmosphere > Aerosols > Carbonaceous aerosols"],"creator":{"@type":"Person","name":"Leonard Kirago, \u00d6rjan Gustafsson, Samuel M.
