Composition of the Atmosphere at 10,000-40,000 Feet Using a Modified Matrix Isolation Technique.
Abstract
A mechanical cryogenic air sampler was adapted so that optical measurements could be made on a frozen air sample. Air samples were to be collected in the 10,000 to 40,000 ft range, but due to aircraft availability difficulties, no air samples were obtained; laboratory studies showed that IR optical spectroscopy was suitable for measuring water vapor and CO2 concentrations at less than 1ppm. Calibration curves for CH4, CO, CO2, N2O and H2O were obtained in the ranges that these gases are found in the atmosphere.
