Received: 25 December 2011; in revised form: 19 January 2012 / Accepted: 19 January 2012 / Published: 9 February 2012 Abstract: The chemical composition of the troposphere in the tropics and Southern Hemisphere (SH) is significantly influenced by gaseous emissions released from African biomass burning (BB). Here we investigate how various emission estimates given in bottom-up BB inventories (GFEDv2, GFEDv3, AM
