:# A mask over the U.S.(1=in U.S. and 0=not in U.S.)  is used to implement these emissions since we do not have original global emission files. NEI99 is used in boxes exclusively U.S., those boxes which have Canadian and Mexican emissions are left as previous 1998 emissions.

:# NEI99 includes both weekend and weekday emissions and those are implemented here.  Diurnal scaling is done as before in GEOS-CHEM.

This page describes the biofuel emissions inventories in GEOS-Chem.

NOTE: Depending on the inventory, biofuels are often lumped together with anthropogenic emissions.

Bond et al 2007 inventory

GEOS-Chem uses the Tami Bond et al (2007) inventory for biofuel emissions of black carbon and organic carbon. For more information about this inventory, please see our carbonaceous aerosols wiki page.
