Rudolf A. Hanel,Barney J. Conrath,W. A. Hovis,Virgil G. Kunde,Paul D. Lowman,William C. Maguire,John C. Pearl,J. A. Pirraglia,C. Prabhakara,B. Schlachman,G. V. Levin,P. Straat,T. E. Burke +12 more
TL;DR: In this article, spectral features due to the atmospheric dust storm indicate that large diurnal variations in atmospheric temperature existed up to at least 30 km; winds inferred from the temperature fields show a strong tidal component and significant ageostrophic behavior.
Journal ArticleDOI

Rudolf A. Hanel,Barney J. Conrath,W. A. Hovis,Virgil G. Kunde,Paul D. Lowman,John C. Pearl,C. Prabhakara,B. Schlachman,G. V. Levin +8 more
TL;DR: Large portions of the thermal emission spectra are significantly affected by dust with a silicon oxide content approximately corresponding to that of an intermediate igneous rock, thus implying that Mars has undergone substantial geochemical differentiation.
Journal ArticleDOI
Infrared Reflectivity of Iron Oxide Minerals
TL;DR: The total reflectivity from 0.5 to 6.0 microns of a number of iron oxide minerals exhibits features that may be useful in remote investigations of the surface of Mars as discussed by the authors.
Journal ArticleDOI
Infrared spectroscopy experiment for Mariner Mars 1971
Rudolf A. Hanel,Barney J. Conrath,W. A. Hovis,Virgil G. Kunde,Paul D. Lowman,C. Prabhakara,B. Schlachman,G. V. Levin +7 more
TL;DR: IR Michelson interferometer for Mariner Mars 1971 mission, investigating atmospheric and surface temperatures and atmospheric water vapor content as mentioned in this paper, was used for the Mars Exploration Program (MEP).
Journal ArticleDOI
Infrared reflectivity of Fe2O3·nH2O: Influence on Martian reflection spectra
TL;DR: In this article, a measure of the infrared reflectivity of limonite and Fe 2 O 3 · n H 2 O from 1 to 5 microns has been made and a strong reflection minimum due to water of hydration is shown.
