MODO - Modtran® for Remote Sensing Applications
MODTRAN is the recognized standard for computing atmospheric transmission and radiance at medium to high spectral resolution (0.1 cm-1). PcModWin wraps around MODTRAN and makes it easy to use. PcModWin is a user-friendly input/output generation system developed by Ontar. It is a Windows-based program that organizes the inputs into screens that. Download MODO - Modtran for Remote Sensing Applications. MODO is a graphical front-end to the original Modtran radiative transfer code. MODTRAN provides two model options for computing multiple scattering contributions, an approximate 2-stream algorithm and the DISORT N-stream model. If the 2-stream model is selected, the surface albedo and solar-direction directional reflectivity are obtained. 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.

What is MODO ?
MODO is a graphical front-end to the original Modtran® radiative transfer code. It has been created to ease the modelling of the at-sensor radiance for hyperspectral sensors but also for generic radiometric simulation tasks.The basic functionality includes:
- running Modtran® through the GUI (creation and translation of tape5-s),
- plotting the Modtran® - outputs,
- extraction and conversion of spectra from the Modtran® - output,
- easy creation of sensitivity analysis series,
- convolution of spectra to hyperspectral band characteristics, and
- simple atmospheric correction for multispectral imagery over flat terrain
The distributions of MODO PRO version 5.1 and MODO version 4 include platform-specific Modtran® executable software,compiled from the original Modtran® code* and is compatible to all current operating systems (Linux/MacOSX/Windows). The MODTRAN executables are available through MODO only.

Overview of MODTRAN®Architecture, Capabilities, and Applications.
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.
