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).

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).

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 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.

Available in PDF, EPUB and Kindle. Book excerpt: Experimental results are given for the absorption coefficient of the liquids hydrogen (three para concentrations), nitrogen, oxygen, carbon monoxide, methane and argon in the wavenumber range 20-250/cm (40-500 milli micros).In addition, data for liquid hydrogen are given at wave numbers up to 600/cm (16.7 milli micros). The results are discussed in terms of the induced dipole, and, in the case of carbon monoxide, the permanent dipole.An indication of the way in which the data may be employed in calculations of thermal radiative transfer is made by calculation of the modified Planck mean absorption coefficient.(Author).
