AEIC emissions inventory
The original AEIC inventory was retired in GEOS-Chem 13.4.0.
Monthly mean aircraft emissions were generated based on 2005 scheduling data from the Aviation Emissions Inventory v2.0, developed by Nick Simone and based on research by Marc Stettler under Steven Barrett. These were implemented into GEOS-Chem by Sebastian D. Eastham.
The following are gridded at a horizontal resolution of 1° x 1°. The emissions are vertically resolved in 60.9 m (200 ft) increments up to 1000 ft, and 1000 ft increments beyond that. The emissions are stored in NetCDF files and read in by aeic_mod.F:
- Fuelburn
- CO
- Hydrocarbons
- NOx
Black and organic carbon (BC/OC) are determined based on an emissions index of 0.03 g/kg fuel burn; sulfur emissions (sulfur dioxide and sulfates) are calculated assuming a fuel sulfur content of 600 ppm by mass and a sulfur conversion efficiency of 2%. The older aircraft NOx emissions have been removed wholesale, while the older sulfur emissions are enabled if AEIC emissions are disabled.
