    Wind measurements with the High Resolution Doppler Imager (HRDI) (1985)
    In:  CASI
    Details
    Publication Date: 2004-12-04
    Description: The Upper Atmosphere Research Satellite (UARS), to be launched in 1989, is to provide a global data set required to understand the mechanisms controlling upper atmosphere structure and processes, as well as the response of the upper atmosphere to natural and human perturbations. The High Resolution Doppler Imager (HRDI) is the primary instrument for measuring the dynamics of the stratosphere and mesosphere. The goal of HRDI is to measure wind velocities in the stratosphere and mesosphere during the day and the mesosphere and thermosphere at night with an accuracy of 5 m/sec. HRDI will determine winds by measuring Doppler shifts of atmosphere absorption and emission features. Line of sight winds will be taken in two directions, thus allowing the wind vector to be formed. The HRDI instrument is overviewed. The basis of the measurement is explained, as is an outline of the instrument. Since neither instrument nor observational techniques is fully mature, only a brief sketch is presented.

    Brightness of the O2 atmospheric bands in the daytime thermosphere (1985)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: The Fabry-Perot interferometer on Dynamics Explorer 2 was used as a low sensitivity photometer to study the O2 Atmospheric A band during the daytime. A study of the brightness of the emission showed that the assumed source of O2(b1Sigma g +) in the thermosphere, O(1D), can account for the observed intensity up to about 250 km but with a significantly different scale height. This combined with an enhanced brightness above this altitude suggests an additional source for this emission.

    Absorption and emission line shapes in the O2 atmospheric bands - Theoretical model and limb viewing simulations (1989)
    In:  Other Sources
    Details
    Publication Date: 2019-07-12
    Description: A multiple scattering radiative transfer model has been developed to carry out a line-by-line calculation of the absorption and emission limb measurements that will be made by the High Resolution Doppler Imager to be flown on the Upper Atmosphere Research Satellite. The multiple scattering model uses the doubling and adding methods to solve the radiative transfer equation, modified to take into account a spherical inhomogeneous atmosphere. Representative absorption and emission line shapes in the O2 1Sigma(+)g - 3Sigma(-)g atmospheric bands (A,B, and gamma) and their variation with altitude are presented. The effects of solar zenith angle, aerosol loading, surface albedo, and cloud height on the line shapes are also discussed.

    The dayglow of the O2 atmospheric band system (1986)
    In:  Other Sources
    Details
    Publication Date: 2019-07-12
    Description: The dayglow of the O2 atmospheric O2(1Sigma) band system has been simulated by taking into account the three main production mechanisms of the O2(1Sigma) state resonance fluorescence, a photochemical term due to quenching of O(1D), and a pure chemical process. Values of the emission rate, which are involved in the resonant scattering of the O2 atmospheric bands (A, B, and gamma), have been obtained as a function of altitude (0-120 km) and solar zenith angle using a line-by-line calculation. The values of the emission rate, along with updated rate coefficients, have been used in the calculation of the production rate of O2(1Sigma) and the volume emission rate of the (O2 1Sigma, v prime = 0)-(O2 3Sigma, v double prime = 0) transition. The results of these calculations are compared to observational measurements and are found to be in excellent agreement.
