There recently has been new interest in the development of faster and more efficient aircraft for intercontinental passenger flights. Such aircraft would likely spend a high fraction of their flight time in the stratosphere. As a natural progression from studies that were done during the CIAP Program in the mid 1970s, this study investigates the sensitivity of stratospheric ozone to NO/sub x/ and HO/sub x/ emissions in conjunction with current understanding of atmospheric chemical and physical processes. The LLNL one-dimensional and two-dimensional chemical-radiative-transport models of the troposphere and stratosphere are used in this investigation. Because of the significant uncertainties in possible future emissions, it is necessary that we examine the models sensitivity to a wide range in magnitude, altitude, and latitude of assumed emissions. As well as examining different NO/sub x/ and HO/sub x/ emission levels, attempts are also made to examine the sensitivity of ozone to emissions under different background amounts of stratospheric chlorine (CIX). These studies lay the groundwork for future studies aimed at analyses of more realistic aircraft emission scenarios.
