Abstract :
Recent developmental efforts involving in the MODTRAN® atmospheric radiative transport model and derivative codes have led to advancements with important implications for hyperspectral imaging. New MODTRAN® features include (a) direct computation of diffuse transmittance and spherical albedo data, (b) two options for computing multiple line-of-sight (MLOS) radiances using a single DISORT scattering calculation for each spectral wavelength or channel and (c) enhancements to the treatment of Earth´s curvature effects on scattered radiances.
