  • Methodologies and protocols for the collection of midwave and longwave infrared emissivity spectra using a portable field spectrometer

    Abstract The development of highly portable field devices for measuring midwave and longwave infrared emissivity spectra has greatly enhanced the ability of scientists to develop and verify exploitation algorithms designed to operate in these spectral regions. These data, however, need to be collected properly in order to prove useful once the scientists return from the field. Attention to ...

  • Comparison of field and laboratory collected midwave and longwave infrared emissivity spectra / data reduction techniques

    Abstract Many targets that remote sensing scientists encounter when conducting their research experiments do not lend themselves to laboratory measurement of their surface optical properties. Removal of these targets from the field can change their biotic condition, disturb the surface composition, and change the moisture content of the sample. These parameters, as well as numerous others, ...

  • The importance of background in the Detection and Identification of Gas Plumes using Emissive Infrared Hyperspectral Sensing

    Abstract Using a Fourier transform infrared field spectrometer, spectral infrared radiance measurements were made of several generated gas plumes against both a uniform sky and terrestrial background. Background temperature, spectral complexity, and physical homogeneity each influenced the success of emissive infrared spectral sensing technology in detecting and identifying the presence of a ...

  • INFRARED TECHNOLOGY - It`s Use in Forensic Building Science to Solve Moisture Intrusion Problems

    This paper will focus discussion on the building envelope, the science behind the inspection, techniques for inspection, and verification of the findings. Because much of our work is pioneering, we will end by addressing the question 'Where do we go from here?' WHY USE INFRAREDA picture says a thousand words; infrared thermography is the only diagnostic technology that lets you instantly ...

  • Canopy gas exchange measurements of cotton in an open system

    A portable, open transparent chamber system for measuring canopy gas exchanges was developed and tested. Differentials between incoming and outgoing atmospheric H2O and CO2 concentrations were used to calculate canopy transpiration (E) and net assimilation (A) at 10-s intervals using solenoid valve actuated sample lines connected to an infrared gas analyzer. A programmable data logger controlled ...

  • Measurement of a Doubly Substituted Methane Isotopologue, 13CH3D

    ABSTRACT: Methane is an important energy resource and significant long-lived greenhouse gas. Carbon and hydrogen isotope ratios have been used to better constrain the sources of methane but interpretations based on these two parameters alone can often be inconclusive. The precise measurement of a doubly substituted methane isotopologue, 13CH3D, is expected to add a critical new dimension to ...
