    Large-scale transport of a CO-enhanced air mass from Europe to the Middle East (1989)
    In:  Other Sources
    Details
    Publication Date: 2011-08-19
    Description: On November 14, 1981, the shuttle-borne Measurement of Air Pollution from Satellites (MAPS) experiment observed a carbon monoxide (CO) enhanced air mass in the middle troposphere over the Middle East. The primary source of this polluted air was estimated by constructing adiabatic isentropic trajectories backwards from the MAPS measurement location over a 36 h period. The isentropic diagnostics indicate that CO-enhanced air was transported southeastward over the Mediterranean from an organized synoptic-scale weather regime, albeit of moderate intensity, influencing central Europe on November 12. Examination of the evolving synoptic scale vertical velocity and precipitation patterns during this period, in conjuction with Meteosat visible, infrared, and water vapor imagery, suggests that the presence of this disturbed weather system over Europe may have created upward transport of CO-enhanced air between the boundary-layer and midtropospheric levels, and subsequent entrainment in the large-scale northwesterly jet stream flow over Europe and the Mediterranean.

    Carbon monoxide mixing ratio inference from gas filter radiometer data (1983)
    In:  Other Sources
    Details
    Publication Date: 2011-08-18
    Description: A new algorithm has been developed which permits, for the first time, real time data reduction of nadir measurements taken with a gas filter correlation radiometer to determine tropospheric carbon monoxide concentrations. The algorithm significantly reduces the complexity of the equations to be solved while providing accuracy comparable to line-by-line calculations. The method is based on a regression analysis technique using a truncated power series representation of the primary instrument output signals to infer directly a weighted average of trace gas concentration. The results produced by a microcomputer-based implementation of this technique are compared with those produced by the more rigorous line-by-line methods. This algorithm has been used in the reduction of Measurement of Air Pollution from Satellites, Shuttle, and aircraft data.

    Foreign-gas-broadening effects in the 15-micron CO2 bands. (1972)
    In:  Other Sources
    Details
    Publication Date: 2011-08-16
    Description: The effects of N2, O2, Ar, and He on the absorption of radiation by the 15-micron perpendicular CO2 bands are reported. The investigation was carried out at medium resolution and at gas pressures less than 1 atm. The results of the study are presented in the form of a band-averaged broadening coefficient for N2, band-averaged broadening factors for O2, Ar, and He, and wavelength dependent broadening coefficients for N2, O2, Ar, and He. Comparisons are made with other experimental and theoretical results. In addition transmittances were calculated for homogeneous paths using some of the molecular parameters determined in the study and compared with measured transmittances.

    Comparison between carbon monoxide measurements from spaceborne and airborne platforms (1991)
    In:  Other Sources
    Details
    Publication Date: 2011-08-24
    Description: The measurements of air pollution from satellites (MAPS) experiment measured the distribution of middle tropospheric carbon monoxide (CO) from the Space Shuttle during October 1984. A critical area of the experiment is the assessment of experimental error of the MAPS data. This error is determined by the comparison between the space-based CO data and concurrent, direct CO measurements taken aboard aircraft. Because of the variability in the CO measurements near land sources, a strategy for comparing the tropospheric CO measurements over the remote oceans is presented.

    Vertical profiles of CO and CH4 in the lower and middle troposphere over the Eastern United States January 1978 (1979)
    In:  Other Sources
    Details
    Publication Date: 2019-06-27
    Description: Samples of tropospheric air were obtained over the Eastern United States during January of 1978. These samples were analyzed by gas chromatography using flame ionization detection to produce vertical profiles of carbon monoxide and methane from the surface to 8 km. The carbon monoxide mixing ratios at 35 deg N and 45 deg N agree with previously published values; however, the mixing ratio at 25 deg N was significantly lower than most published values. The methane mixing ratio was weakly dependent on latitude and has an average value of 1.64 ppm.

    Measurements of CO and CH4 in the troposphere over Saudi Arabia, India, and the Arabian Sea during the 1979 International Summer Monsoon Experiment /MONEX/ (1981)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: During the 1979 Summer MONEX, 150 air samples collected over Saudi Arabia, India, and the Arabian Sea were analyzed for CO and CH4. Near Dhahran and over the Ganges Valley there were high concentrations of CO, around 300 ppbv, in the boundary layer. Out over the Saudi Arabian desert there was no sharp increase in the boundary layer. It is suggested that these high concentrations originate from pollution sources. Low values of CO, down to 80 ppbv, are found over the Arabian Sea as the monsoon progresses, and these may originate from the Southern Hemisphere. Methane over Saudi Arabia (1.59 ppmv) is a little higher than that over the Arabian Sea (1.54 ppmv) probably because the latter region is influenced by air from the Southern Hemisphere.

    Tropospheric CO measurement experiment from the second Space Shuttle flight (1982)
    In:  Other Sources
    Details
    Publication Date: 2019-07-13
    Description: The MAPS experiment was designed to remotely measure the mixing ratio of carbon monoxide in the middle and upper troposphere using a gas filter radiometer as the sensing instrument. The asymmetrical worldwide distribution of CO is discussed as background, and the experimental scientific and technical objectives are briefly stated. The gas filter radiometer is described in detail, and the second Shuttle mission is summarized. Auxiliary and correlative data were obtained in order to evaluate the performance of the measurement system, to assess the effect of stratospheric ozone on the radiometer signals, and to determine the effect of the underlying surface. The experiment acquired about 32 hours of data between 38 deg N and 38 deg S, signal-to-noise ratios were as predicted and the instrument achieved satisfactory stability in spite of large temperature variations. Data reduction is in progress.
