Abstract:

In the near future commercial aircraft SSTs will be in routine schedule operation. Environmental experts have exhibited a variety of concerns over possible adverse effects the effluents from such flights may have upon the earths climate. Unfortunately many of these prognostications are based on rather sketchy data as to the normal chemical composition of the atmosphere. In the program the matrix isolation technique is to be adapted to the cryogenic sampling of the atmosphere at altitudes of 40,000-65,000 Ft. The following species are to be monitored H2O, H2O2, NO, NO2, N2O5, HNO3, O3, OH, HO2, CO, and CH4. The report discusses the design and construction of the cryogenic sampling system and the design and construction of a ground power support system.
