There recently has been renewed interest in the development of faster and more efficient aircraft for intercontinental passenger flights. Such aircraft would probably spend a large fraction of their flight time in the stratosphere, perhaps as high as 35 km. As a natural progression from studies that were done in the early 1970s, this study reinvestigates the sensitivity of stratospheric ozone to NO/sub x/ emissions based on current understanding of atmospheric chemical and physical processes. The LLNL one-dimensional and new two-dimensional chemical-radiative-transport models of the troposphere and stratosphere are used in this investigation. The two-dimensional model provides latitudinal, altitudinal, and seasonal resolution; and the computationally faster one-dimensional model is used for sensitivity studies. Because of uncertainties in possible future emissions, it is necessary to examine the model sensitivity to a wide range in magnitude, altitude, and latitude of assumed NO/sub x/ emissions. As an initial study, the models are used in simulation of a typical scenario from the CIAP era, and results are compared with those of a published two-dimensional model, which includes some three- dimensional features. This investigation lays the groundwork for future studies, including different background amounts of ClX and for other aircraft emission scenarios. 12 refs., 3 figs., 1 tab.
