Book Synopsis Cryogenic, Whole-air Sampler and Program for Stratospheric Composition Studies by : Charles C. Gallagher
Download or read book Cryogenic, Whole-air Sampler and Program for Stratospheric Composition Studies written by Charles C. Gallagher and published by . This book was released on 1976 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: A program has been initiated to measure the stratospheric content of NO, NO2, CO, SO2, CH4, NH3 and other trace gases which may influence our environment. The initial or baseline concentrations of these gases are being measured as a function of altitude and latitude. Subsequent measurements will indicate any time dependency in these concentrations and permit a possible correlation with increased Air Force stratospheric operations. Latitudes from Panama to Alaska and altitudes from 12 to 30 km will be investigated. (Author).

Book Synopsis Composition Alteration of Stratospheric Air Due to Sampling Through a Flow Tube by : J. M. Calo
Download or read book Composition Alteration of Stratospheric Air Due to Sampling Through a Flow Tube written by J. M. Calo and published by . This book was released on 1984 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: A numerical model of a sampling tube used to conduct stratospheric air to the sampling point of a balloon-borne cryogenic whole air sampler, was developed to assess the potential effects of passage through the tube on alteration of species mixing ratios from those in the ambient. This model is based on the application of a general purpose, multireaction chemical kinetics code (CHEMSEN) to a 31 reaction (49 with heterogeneous wall loss), 23 species (41 with adsorbed or 'lost' constituents) stratospheric kinetic model, modified to take into account heterogeneous interactions with the tube wall. Effects of homogeneous gas phase chemistry and heterogeneous wall loss were estimated at three different altitudes: 15, 20, and 30 km. It was found that the gas phase chemistry was generally incapable of appreciably altering the sampled composition from that in the ambient. On the other hand, depending on the particular set of assumptions used, heterogeneous wall loss was found capable of imposing significant alterations on the sampled gas composition, particularly at altitudes above about 20 km, due to rapid radial diffusion. The expected tube wall temperature is shown to have a negligible effect on the homogeneous gas phase kinetics in the sampling tube.
Book Synopsis Modified Gas Valve for Improved Balloon Descent Control by : George F. Nolan
Download or read book Modified Gas Valve for Improved Balloon Descent Control written by George F. Nolan and published by . This book was released on 1980 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability to control balloon descent rates has been improved through use of a modified gas valve which has a range of openings. The descent rates obtained with this valve are more constant than those obtainable with the standard gas valve. Atmospheric temperature lapse rate and other thermal and aerodynamic influences are unquantifiable factors affecting balloon vertical motion, but are better compensated for when use is made of a variable opening gas valve. Even with this valve, slow descents on the order of 200 fpm or less will have oscillations with short periods of time when ascents and leveling off will occur. (Author).
