My watch list  


MODTRAN (MODerate resolution atmospheric TRANsmission) is a computer program designed to model atmospheric propagation of electromagnetic radiation from 100-50000 cm-1 with a spectral resolution of 1 cm-1.

The spectral region covered is the far-infrared (100 cm-1 is 100µm wavelength), through visible light, to the deep ultraviolet (50000 cm-1 is 200 nm).

Some aspects of MODTRAN are patented by the US Air Force. Software licenses are issued by the USAF but distribution is handled by Ontar Corporation. MODTRAN core modules are written in FORTRAN.
