Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1981 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impact of high altitude aviation on stratospheric ozone is now believed to be a decrease in total columnar ozone for flights above 15 km (about 49,000 feet). The model calculations also show that the current subsonic fleet (and the fleet foreseeable to 1990) will result in a net ozone increase of about 1 percent, considering normal flight altitudes. Whatever the net change in total column ozone, increases or depletions will occur at different altitudes. These are expected to have subtle influences on atmospheric circulation, the effects of which are only beginning to be understood. As a formal program, the High Altitude Pollution Program will be terminated in 1982 with the issuance of a final report. The FAA will continue to maintain and update, as appropriate, its capability to make quantitative assessments of the environmental effects of cruise-altitude emissions, and will monitor and assist, as possible, other research programs, both here and abroad.

Available in PDF, EPUB and Kindle. Book excerpt: This report pertains to the feasibility of developing a Stratospheric Measurement System, which is a key element of the FAA High Altitude Pollution Program (HAPP). Analytical measurement concepts considered during the study for the oxides of nitrogen and ozone are identified and ranked in Tables 3-1 and 3-40, respectively. Scientific ballooning considerations were also examined in the main study to the extent necessary to determine overall feasibility of developing a Stratospheric Measurement System (SMS). The conclusion of the study is that there exists a set of analytical techniques that can be flown on a balloon platform to obtain the specified HAPP/SMS measurements. A conceptual design of the integrated system is presented.

This book was released on 1980 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: The High Altitude Pollution Program (HAPP) Scientific Advisory Committee held its second meeting during March 28-30, 1979 at the Federal Aviation Administration (FAA) Headquarters in Washington, D.C. The purpose of this meeting was to discuss the field measurement experiments. Atmospheric measurements from a critical element in the validation process of the atmospheric models used to assess the impact of the aviation on the stratosphere. The Federal Aviation Administration carries out these measurements in cooperation with the National Aeronautics and Space Administration and the National Oceanic and Atmospheric Administration. Principal investigators working on different aspects of the field measurements program presented technical progress reports to the Committee. Such issues as the measurement strategy, data utilization, and coordination wit other Federal programs were discussed. This Executive Summary includes the Committee Chairman's presentation of the findings of the meeting to the Acting Director of Environment and Energy as Part I and the Committee's recommendations for field measurements (as noted by the Rapporteur) as Part II. Three appendixes at the end contain the meeting agenda, list of attendees and participants, and the Committee Charter and membership respectively. (Author).
