MODTRANIt is,MODerate resolution atmospheric TRANSmission It is an atmospheric radiative transfer model jointly developed by the US Air Force Research Laboratory (AFRL) and Spectral Sciences (SSI).

In the ultraviolet to long-wave infrared spectral region (0 – 50,000 cm-1; > 0.2 μm), MODTRAN's six model atmospheric temperature profiles (geographical and meteorological conditions), aerosol models (ground boundary layer altitude 6- 0km meteorological range), satellite observation position (altitude and zenith), and wavelength band are set, the atmospheric spectral transmittance and atmospheric upward radiance, and the spectral radiance reaching the satellite sensor can be calculated.
