Overview
NOx
The inventory of aircraft NOx used in GEOS-Chem is described in Wang et al [1998]:
For NO emissions from subsonic aircraft, we adopted the 1992 monthly mean emisison inventory compiled by Baughcum et al [1996] and Metwally [1995]; the inventory has a resolution of 1° x 1° x 1 km, and the global source is 0.51 Tg N/yr.
The source code for the aircraft NOx emissions inventory is aircraft_nox_mod.f.
For more information about the data files, please see the following READMEs:

Due to the common block error described by Lee Murray, in GEOS-Chem v7-04-13 we have added a new module array (EMIS_AC_NOx) to "aircraft_nox_mod.f". The EMIS_AC_NOx array will be referenced in routine "setemis.f", which will pass the aircraft NOx emissions to the SMVGEAR solver. The old common-block array "GEMISNOX" will be removed.
SO2
From Park et al
Other anthropogenic sources of SO2 in the model include gridded monthly aircraft emissions (0.07 Tg S yr�1) taken from Chin et al. [2000a]
