The High Altitude Pollution Program (HAPP) was initiated by the Federal Aviation Administration in 1976 in order to assess the effects of aircraft engine emissions on the upper atmosphere. Its predecessor, the Climatic Impact Assessment Program (1971-1975) conducted by the U.S. Department of Transportation, focused international attention on the ozone depletion problem. This final report documents the conclusions of the studies funded by HAPP from 1976 until the program was terminated in 1982. Scientific considerations of the impacts of aircraft engine emissions on the stratosphere and troposphere are discussed. Major HAPP accomplishments in the areas of engine emissions, laboratory studies, field measurements, and modeling are summarized. Current evaluations of the effects of aircraft engine NOx emissions (through 1984) are also contained in the report. Based upon the studies undertaken, it appears that there is no immediacy of concern with regard to ozone and climatic changes that may result from the operations of civilian aircraft at this time.
