Monthly mean aircraft emissions were generated based on 2005 scheduling data from the [https://lae.mit.edu/datasets/ Aviation Emissions Inventory v2.0], developed by [mailto:nsimone@mit.edu Nick Simone] and based on research by [mailto:mejs@mit.edu Marc Stettler] under [mailto:sbarrett@mit.edu Steven Barrett]. These were implemented into GEOS-Chem by [mailto:seastham@mit.edu Sebastian D. Eastham].
The following are gridded at a horizontal resolution of 1&deg; x 1&deg;. 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 <tt>aeic_mod.F</tt>:
# 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.

Latest revision as of 20:40, 13 July 2023

This page describes the aircraft emissions inventories used by GEOS-Chem.

AEIC 2019 emissions inventory

An updated version of the AEIC aircraft emissions (named AEIC 2019) was introduced in GEOS-Chem 13.4.0.
