  • Bright air : geoprocessing thermal imagery to map the nocturnal dynamics of the boundary layer in a mountain valley

    Creator:
    Johnson, Christopher
    Abstract:
    A thermal infrared (TIR) camera is used to remotely sense the foliage temperature in a mountain valley. The foliage temperature is used as a proxy for air temperature and can be used to study and map the dynamics of the nocturnal, weak-wind boundary layer in this valley. All radiative flux...

  • Estimating ground cover via spectral data

    Creator:
    Axness, Daniel S.
    Abstract:
    Potato ground cover and spectral data were measured in the Columbia Basin during the 1990 growing season. Three spectral were correlated with ground cover; normalized difference, near infrared-red ratio, and the first derivative of the spectral curve at 750 nm. All models were statistically significant at the 99% level. Normalized...
