  1. The far-ultraviolet spectroscopy of molecules of astrophysical interest

    … stars whose far-ultraviolet emission is intense. Laboratory spectroscopy of such molecules will lead to a better understanding of their astrophysical behaviour, in particular Celestial Masers. This thesis is preoccupied with the spectroscopy of H$_{2}$O, D$_{2}$O, OH, CO, and C$_{2}$H$_{2}$ in the …

  2. Remote Sensing of Hydrocarbon-induced Rock Alterations at Cement Field, Oklahoma

    … as crystallization gradient of gypsum samples. Laboratory spectroscopy was used to assist with image classification. Principal component analysis, minimum noise fraction, spectral angle mapper, and band ratios are used in image processing. Remote sensing data detected bleaching and carbonate …

  3. Chemical physics and astrochemistry of H3+ and sub Doppler mid infrared spectroscopy of molecular ions

    … temperatures are described. The results of these laboratory measurements are included into a model of the hydrogenic chemistry of diffuse molecular clouds, in which an excess of para-H3+ is observed relative to its expected abundance at the measured cloud temperature. The model suggests that the …

  4. Validation and application of the MERIS Terrestrial Chlorophyll Index.

    … content and MTCI that was evident from laboratory spectroscopy investigations, demonstrating the suitability of the MTCI as a surrogate for field chlorophyll content measurements independent of cover type. However, this relationship was significantly weakened where the leaf area index …

  5. Radiative transfer modeling of thermal infrared emissivity spectra: applications to martian regolith observations

    … Few measurements have been attempted in the laboratory or field regarding directional emissivity effects of planetary regoliths; such measurements are necessary for modeling and interpreting directional emissivity effects that are clearly present in the Mars Global Surveyor Thermal Emission …

  6. Post-shock thermochemistry in hypervelocity CO2 and air flow

    … in anticipation of the upcoming Mars Science Laboratory (MSL) and future missions to the red planet. The work is motivated by observed anomalies between experimental and numerical studies in hypervelocity impulse facilities for high enthalpy carbon dioxide flows. In this work, experiments are …
