This book was released on 1971 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The continuum absorption by H2O between 2400 and 2780/cm and by N2 between 2400 and 2650/cm has been measured. The H2O data cover the temperature range from 338 K to 428 K and are primarily for pure H2O. A few preliminary results for H2O + N2 mixtures are discussed. Calculated values of the continuum- absorption coefficient are compared with the experimental results. From absorption data on samples of pure N2 and of N2 + O2 at different temperatures, the attenuation by atmospheric N2 has been calculated for a range of temperatures encountered in the atmosphere. The strengths of several N2O bands between 1100 and 660/cm have been measured and are tabulated.

This book was released on 1971 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental data are presented on the absorption by a variety of N2O samples between 760 and 2380/cm. Most of the absorption between 760 and 850/cm is due to extreme wings of lines centered outside the interval. Strengths of the important band systems are given. Curves of transmittance and tables of integrated absorptance and the integrated absorption coefficient provide detailed information on the absorption. The objective of the study was to provide the data required to determine the parameters of all N2O absorption lines that absorb significantly over any atmospheric path of interest. (Author).

This book was released on 1970 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The continuum absorption by H2O between 800 and 1250/cm and by CO2 from 780 to 900/cm has been measured. The continuum results from the extreme wings of very strong absorption lines centered outside the 800-1250/cm interval. Experimental results are compared with calculated values based on various line shapes. The extreme wings of N2-broadened H2O lines produce less than 0.005 as much continuum absorption as self-broadened H2O lines at the same pressure. Self-broadened H2O lines absorb more than Lorentz-shaped lines, but the wings of self-broadened CO2 lines absorb only approximately 0.01 as much in the 780-900/cm region as if they had the Lorentz shape. The shapes of the wings of the CO2 lines which produce the continuum between 780 and 900/cm are similar to those near 2400/cm for both self broadening and N2 broadening. Suggestions on methods for using the results for atmospheric transmission calculations are given.

This book was released on 1969 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report summarizes work devoted to the emission of hot H2O and CO2 and to the absorption by these same gas species and other atmospheric constituents. The emission work involved a furnace and gas-handling system which could heat samples to approximately 2000K with the sample at nearly-uniform temperature and pressure. Many of the data have been presented in great detail in scientific reports in the form of tables of transmittance and integrated absorptance versus wavenumber. Strength of many absorption bands have been determined, and widths of the lines have been investigated. More than 25 weak bands of CO2 which had not been reported previously have been observed and identified. New information on the shapes of the extreme wings of CO2 and H2O absorption lines has been obtained. The shapes have unpredicted dependence on the broadening gas and temperature. (Author).

This book was released on 1988 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although both Carbon Dioxide and Nitrous Oxide are minor constituents of the terrestrial atmosphere, they play leading roles in several current atmospheric problems. Both CO2 and N2O are greenhouse gases, and while it is known that the atmospheric concentrations of both gases is increasing, the impact of these trends on global temperature is not yet adequately understood. In addition to being a greenhouse gas, N2O plays an indirect part in ozone chemistry. Heating a molecule makes possible the observations of molecular transitions originating from highly excited rotation-vibration states. Heating a molecule makes possible the observations of molecular transitions originating from highly excited rotation-vibration states. These observations can then be used to characterize the shape of the molecular potential function at increasing distances from the minimum of the potential function. The infrared spectra of linear molecules like CO2 and N2O are composed of vibration bands made up of a number of nearly equally spaced rotation lines. A Fourier Spectrometer is ideally suited to the study of high temperature gases since it meets both of these needs by providing high resolution over a wide spectral region.

Book excerpt: All of the N2O bands expected to absorb significantly between 4000 and 6700/cm have been listed, and the strengths of several of the stronger bands have been determined. Spectral curves are shown for samples at low pressure so that the line structure remains and for samples at approximately 15 atm with the structure smoothed out. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The work involves an experimental investigation of the absorption of infrared radiation by atmospheric gases, and a study of the emission by H2O and CO2 at temperatures as high as 2000K. Several hundred absorption spectra of H2O and CO2 samples near room temperature were obtained in the 0.7 to 5.5 micron region. The samples varied in path length from 1 cm to 933 meters and pressures ranged from approximately 5 microns Hg to 15 atmospheres. Strengths of many of the bands were determined and the widths of many of the individual lines were calculated. Abstracts of the technical reports and papers are presented. (Author).

Book excerpt: New and Future Developments in Catalysis is a package of seven books that compile the latest ideas concerning alternate and renewable energy sources and the role that catalysis plays in converting new renewable feedstock into biofuels and biochemicals. Both homogeneous and heterogeneous catalysts and catalytic processes will be discussed in a unified and comprehensive approach. There will be extensive cross-referencing within all volumes.The use of solar energy during various catalytic chemical processes for the production of an array of chemical products is the theme of this volume. Photocatalysis is a topic of increasing importance due to its essential role in many of today’s environmental and energy source problems. The use of solar energy for catalytic reactions results in a carbon dioxide–neutral process. All photocatalytic processes and the future developments in this area are discussed, including an economic analysis of the various processes. Offers in-depth coverage of all catalytic topics of current interest and outlines future challenges and research areas A clear and visual description of all parameters and conditions, enabling the reader to draw conclusions for a particular case Outlines the catalytic processes applicable to energy generation and design of green processes

Available in PDF, EPUB and Kindle. Book excerpt: "We describe a method of simulating measurements of atmospheric radiances and brightness temperatures in wide-bank window channels (at 11 and 3.7 um) of satellite radiometers. As input the simulation takes vertical profiles of atmospheric temperature and water-vapor mixing ratio, as well as the spectral response functions of the window channels. It models the atmospheric transmittances and integrates the equation of radiative transfer. We demonstrate the use of the method with applications to the Advanced Very High Resolution Radiometer on the TIROS-N satellite."--p.1.
