Atmospheric Effects of Aviation: First Report of the Subsonic Assessment Project

摘要

This document is the first report from the Office of Aeronautics AdvancedSubsonic Technology (AST) Program's Subsonic Assessment (SASS) Project. This effort's objective is the assessment of the atmospheric effects of the current and predicted future aviation fleet. The two areas of impact are ozone (stratospheric and tropospheric) and radiative forcing. These are driven, respectively, by possible perturbations from aircraft emissions of NOX and soot and/or sulfur-containing particles. The report presents the major questions to which project assessments will be directed (Introduction) and the status of six programmatic elements: Emissions Scenarios, Exhaust Characterization, Near-Field Interactions, Kinetics and Laboratory Studies, Global Modeling, and Atmospheric Observations (field studies).
