E. Abstract: The Multilevel Diffusion Model (MDM) Version 5 was modified to include features of more recent versions. The MDM was used to predict in-cloud HCl concentrations for the April 12 launch of the space Shuttle (STS-1). The ... NASA Center: NASA (non Center Specific) Publication Year: 1981 Added to NTRS: 2004-11-03 Accession Number: 82N17653; Document ID: 19820009779; Report Number: NASA-CR-167497 Oxidation of SO2 by NO2 and air in an aqueous suspension of carbon Author(s): Rogowski, R. S.; Schryer, D. R.; Cofer, W. R., III; Edahl, R. A., Jr.; Munavalli, S. Abstract: A series of experiments has been performed using carbon black as a surrogate for soot particles. Carbon black was suspended in water and gas mixtures were bubbled into the suspensions to observe the effect of carbon ... NASA Center: Langley Research Center Publication Year: 1982 Added to NTRS: 2004-11-03 Accession Number: 83A25193; Document ID: 19830043975 Pathways of nitrogen loss following land clearing in a humid tropical forest Author(s): Matson, Pamela; Vitousek, Peter Abstract: Tropical deforestation generally leads to large losses of carbon and nitrogen. The Premontane Wet Forest Life Zone is subject to the highest rate of deforestation in Central America, and carbon and nutrient losses in from ... NASA Center: Ames Research Center Publication Year: 1985 Added to NTRS: 2004-11-03 Accession Number: 93N70607; Document ID: 19930073160 Chemistry of the global troposphere - Fluorocarbons as tracers of air motion Author(s): Prather, Michael; Russell, Gary; Rind, David; Mcelroy, Michael; Wofsy, Steven Abstract: Winds and convective mixing from a general circulation model of the atmosphere have been applied in a chemical tracer model (CTM) to simulate the global distribution and temporal variability of chlorofluorocarbons (CFCs). ...

M.; Glenn, M. J.; Nolt, I. G.; Carli, B.; Carlotti, M. Abstract: The stratospheric vertical distribution of CO is obtained from balloon-based FIR limb thermal emission spectra by analyzing several limb sequences of the R8 and R1 spectral lines at 34.588 and 49.932/cm, respectively. This ...

B.; Ackerman, T. P. Abstract: In their reply (Porch et al., 1987) to our comments (Turco et al., 1987) on their smoke-scavenging-by-dust paper, Porch et al. attempt to justify a number of parameter assumptions in their original article, again revealing ... NASA Center: Ames Research Center Publication Year: 1987 Added to NTRS: 2004-11-03 Document ID: 20000021124 The potential impact on atmospheric ozone and temperature of increasing trace gas concentrations Author(s): Brasseur, G.; Derudder, A. Abstract: The response of the atmosphere to emissions of chlorofluorocarbons (CFCs) and other chlorocarbons, and to increasing concentrations of other radiatively active trace gases such as CO2, CH4, and N2O is calculated by a coupled ... NASA Center: NASA (non Center Specific) Publication Year: 1987 Added to NTRS: 2004-11-03 Accession Number: 88N24112; Document ID: 19880014728; Report Number: AERONOMICA-ACTA-A-322-1987, NAS 1.26:182965, NASA-CR-182965 Ecological applications of high resolution spectrometry Author(s): Lawrence, William T. Abstract: Future directions of NASA's space program plans include a significant effort at studying the Earth as a system of interrelated ecosystems. As part of NASA's Earth Observing System (Eos) Program a series of space platforms ...
