<blockquote>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&deg; x 1&deg; x 1 km, and the global source is 0.51 Tg N/yr.</blockquote>

=== 02-Oct-2007 ===
Due to the [[Lightning_NOx_emissions#The common block bug fix|common block error described by Lee Murray]], in [[GEOS-Chem_versions_under_development#v7-04-13|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.
