GEOS-5 GMI Configuration for PIESA: Difference between revisions

*Global biofuel CO emissions are from Yevich et al. (2003). These are overwritten with EPA/NEI 1999 biofuels over the United States. 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.

*To account for CO production from co-emitted non-methane hydrocarbons, we scale up fossil fuel CO emissions by 2%, biofuel CO emissions by 8.6%, and biomass burning CO emissions by 5%.

===VOC sources===

*Global fossil fuel emissions of MEK, PRPE, C2H6, C3H8, and ALK4 come from GEOS-Chem's inventory for 1985 (Wang et al. 1998), based on speciation information from EPA. Annual scaling of VOC's uses the same scaling factors as CO.

*The following regional inventories overwrite the global VOC emissions:

**EPA/NEI 2005 over the United States for all species, with seasonality from EPA/NEI 1999

**EMEP over Europe for MEK, PRPE, C2H6, and ALK4

**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.
