* CMIP5 anthropogenic emissions are broken down by source category. We treat the “agricultural waste burning” category as the biofuel input for GOCART, and sum the other anthropogenic categories for the anthropogenic input. Ship and aircraft emissions are input separately. | * CMIP5 anthropogenic emissions are broken down by source category.

* We convert CMIP5 aircraft BC emissions to fuel emissions for GOCART using the altitude-dependent emission ratios from Aerocom, which are based on Döpelheuer’s thesis (2002). See readme_aerocom_aircraft.docx for more information. We then regrid the aircraft data to 72 GEOS5 vertical levels. | * We convert CMIP5 aircraft BC emissions to fuel emissions for GOCART using the altitude-dependent emission ratios from Aerocom, which are based on Döpelheuer’s thesis (2002).
