Reformulation of the MODTRAN band model for higher spectral resolution
SPIE Proceedings, 2000The MODTRAN 1 cm-1 band model has been reformulated for application to higher spectral resolution. Molecular line center absorption is still determined from finite spectral bin equivalent widths but is now partitioned between the bin containing the molecular transition and its nearest neighbor bin.

Modification of the method of parametric estimation of atmospheric distortion in MODTRAN model
SPIE Proceedings, 2015The paper presents a modification of the method of parametric estimation of atmospheric distortion in MODTRAN model as well as experimental research of the method. The experimental research showed that the base method does not take into account physical meaning of atmospheric spherical albedo parameter and presence of outliers in source data that ...

Modtran®6 Multiple Line-Of-Sight (MLOS) Option
IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018The MODTRAN6 radiative transfer model enjoys widespread use throughout the remote sensing community. A multiple line-of-sight option is now available that dramatically increases processing time when spectral transmittances and radiances are required for multiple paths within a scene.

Accuracy of lowtran 7 and modtran in the 20–55-μm region
Applied Optics, 1994LowTRAN 7 and MODTRAN were evaluated in the 2.0-5.5-µm region against field-collection data at high zenith angles and long path lengths to determine the degree of uncertainty associated with these models under these conditions. Matching data sets were developed with data from the U.S.

Exploiting MODTRAN radiation transport for atmospheric correction: The FLAASH algorithm
Proceedings of the Fifth International Conference on Information Fusion. FUSION 2002. (IEEE Cat.No.02EX5997), 2003Terrain categorization and target detection algorithms applied to hyperspectral imagery (HSI) typically operate on the measured reflectance (of sun and sky illumination) by an object or scene. Since the reflectance is a non-dimensional ratio, the reflectance by an object is nominally not affected by variations in lighting conditions.

Abstract : This report summarizes the work performed by Spectral Sciences Inc. (SSI) during FY under the SERDP program for atmospheric radiance algorithm optimization. The task consisted of (1) adding infrared CFC cross sections and concentration profiles to MODTRAN for transmittance and radiance calculations, and (2) investigation the use of MODTRAN ...
