The 11-level Geophysical Fluid Dynamics Laboratory global chemical transport model (GCTM), which explicitly treats NO(x), HNO3, and PAN as transported species, has been used to assess the impact of sub-sonic aircraft emissions on the distribution of reactive nitrogen compounds (NO(y)) in the atmosphere. A 3D aircraft source inventory compiled by Boeing and McDonnell Douglas has been used, in conjunction with previously compiled surface-based fossil-fuel combustion and stratospheric source inventories. Consistent with previous 2D model calculations, we find that aircraft emissions have a significant impact on upper tropospheric NO(x) and HNO3 budgets in the mid- and high latitudes of the Northern Hemisphere. The relative impact of the aircraft source on upper tropospheric NO(x) levels at mid- and high northern latitudes varies longitudinally, and that in certain regions the aircraft source dominates the total NO(x) budget. Aircraft emissions appear to only minimally impact the NO(y) budget in the Northern Hemisphere lower troposphere, and in much of the Southern Hemisphere. Comparisons of model results with NO(y) measurements at Mauna Loa, Hawaii, and over western Alaska suggest that sources other than surface-based fossil-fuel combustion, stratospheric NO(x) production, and aircraft emissions, are significant in determining the free tropospheric NO(y) budget in these regions.
