Infrared land surface remote sensing using high spectral resolution aircraft observations Original Research Article

A method for emissivity–temperature separation using high spectral resolution infrared observations is presented. An additional constraint is available with high spectral resolution observations that allow for the determination of an effective surface temperature and effective surface emissivity spectrum appropriate for advanced atmospheric temperature and water vapor sounders. The method is illustrated using observations from a high altitude aircraft over a ground truth site in North Central Oklahoma, USA.
