The Climatic Impact Assessment Program (CIAP) of the U.S. Department of Transportation is charged with the assessment of the impact of future aircraft fleets and other vehicles operating in, or transiting through, the stratosphere. Monograph 3 considers the perturbations of the radiation fluxes, and therefore the composition of the stratosphere, that are produced by the emission of engine effluents from potential, large-scale operations of aircraft in the lower stratosphere (e.g., 29 to 69 kft or 9 to 21 km). The important engine emissions are the odd nitrogen oxides (NO/sub x/ or NO and NO/sub 2/), sulfur dioxide (SO/sub 2/), and water vapor (H/sub 2/O). Monograph 3 considers the significant perturbations in the composition of the radiative species in the stratosphere, which include ozone (O/sub 3/), nitrogen dioxide (NO/sub 2/), sulfuric acid aerosols (75 percent H/sub 2/SO/sub 4/), and water vapor. These considerations require an understanding of complex phenomena involving radiative, chemical, dynamic, and thermodynamic processes in the stratosphere. Since CIAP is concerned with predictions of effects that take place in the distant future, the methodology used for this purpose is based on models of atmospheric phenomena. (GRA)
