MODTRAN software produces integrated transmission and radiance at the sensor along a line of sight from all sources including cloud and aerosol scatter. MODTRAN models include fully featured atmospheric transmission, reflection, refraction and absorption of light. Millions of MODTRAN calculations can be run and used to produce a realistic multi-color scene simulation or remove atmospheric effects from multi-color remotely sensed imagery.
