Trace gas emissions from fossil fuels, biofuels, and biomass burning are based on inventories and routines provided by the Harvard University GEOS-Chem group. Individual sources are described below. The general approach for fossil fuel and biofuel emissions is to begin with a global inventory and overwrite particular regions where regional inventory data is available. Fossil fuel emissions are scaled from the inventory base year to the simulation year using scaling factors from the Harvard University GEOS-Chem group (''van Donkelaar et al.'', 2008). Biomass burning emissions use emission factors for boreal forest, tropical forest, and savanna/herb/other vegetation types to convert ~~GFED2~~ carbon emissions to emissions of NOx, CO, or VOCs.

**For 2006 and later, Zhang et al. (2009) inventory for 2006 over southeast Asia

*Biofuel emissions of MEK, PRPE, C2H6, C3H8, ALK4, CH2O, and ALD2 come from Yevich et al. (2003). All species except CH2O are overwritten with EPA/NEI1999 biofuels over the US. For years 2006 and later, biofuel emissions are zeroed over southeast Asia to avoid double counting because the 2006 inventory for southeast Asia does not separate fossil fuels and biofuels.
