Abstract :
Several theoretical calculations are presented and our approach discussed for simulating overall composite scene thermal infrared exitance and canopy bi-directional reflectance of a forest canopy. Calculations are performed for selected wavelength bands of the DOE Multispectral Thermal Imagery and comparisons with atmospherically corrected MTI imagery are underway. NASA EO-1 Hyperion observations also are available and the favorable comparison of our reflective model results with these data are reported elsewhere.
