MODTRAN5: A Reformulated Atmospheric Band Model with Auxiliary Species and Practical Multiple Scattering Options

Abstract

The MODTRAN5 radiation transport (RT) model is a major advancement over earlier versions of the MODTRAN atmospheric transmittance and radiance model. The new model's features include the following: (1) finer spectral resolution via the Spectrally Enhanced Resolution MODTRAN (SERTRAN) molecular band model, (2) a fully coupled treatment of auxiliary molecular species, and (3) a rapid and high-fidelity multiple scattering (MS) option. The finer spectral resolution improves model accuracy, especially in the intermediate- and long-wave infrared spectra. The auxiliary species will permit the addition of any or the entire suite of HITRAN species, along with default and user-defined profile specifications. The MS option makes feasible the calculation of Vis-NIR (Near InfraRed) databases that include high-fidelity scattered radiances. (9 figures, 11 refs.)
