Overview of MODTRAN®Architecture, Capabilities, and Applications.
HITRAN is an acronym for hi gh-resolution tran smission molecular absorption database. HITRAN is a compilation of spectroscopic parameters that a variety of computer codes use to predict and simulate the transmission and emission of light in the atmosphere.
The MODTRAN® (Berk et al., 2014) (Berk et al., 2008) (MODerate resolution atmospheric TRANsmission) computer code is used worldwide by research scientists in government agencies, commercial organizations, and educational institutions for the prediction and analysis of optical measurements through the atmosphere. MODTRAN was developed and continues to be maintained through a longstanding collaboration between Spectral Sciences, Inc. (SSI) and the Air Force Research Laboratory (AFRL). The code is embedded in many operational and research sensor and data processing systems, particularly those involving the removal of atmospheric effects, commonly referred to as atmospheric correction, in remotely sensed multi- and hyperspectral imaging (MSI and HSI).
The MODTRAN software computes line-of-sight (LOS) atmospheric spectral transmittances and radiances over the ultraviolet through long wavelength infrared spectral regime (0 - 50,000 cm-1; > 0.2 μm). The radiation transport (RT) physics within MODTRAN provides accurate and fast methods for modeling stratified, horizontally homogeneous atmospheres. The core of the MODTRAN RT is an atmospheric 'narrow band model' algorithm. The atmosphere is modeled via constituent vertical profiles, both molecular and particulate, defined either using built-in models or by user-specified radiosonde or climatology data. The band model provides resolution as fine as 0.2 cm-1 from its 0.1 cm-1 band model. MODTRAN solves the radiative transfer equation including the effects of molecular and particulate absorption/emission and scattering, surface reflections and emission, solar/lunar illumination, and spherical refraction.

The underlying physics and algorithms used in MODTRAN are well established and, with over a 30 year heritage, MODTRAN has been extensively validated, serving as the community standard atmospheric band model.
Our Atmospheric LUT Generator (ALG) toolbox supports usage of MODTRAN version 5 (Berk et al., 2006) and version 6 (Berk et al., 2015).
