MODTRAN6: a major upgrade of the MODTRAN radiative transfer code
Proceedings of SPIE, 2014The MODTRAN6 radiative transfer (RT) code is a major advancement over earlier versions of the MODTRAN atmospheric transmittance and radiance model. This version of the code incorporates modern software ar- chitecture including an application programming interface, enhanced physics features including a line-by-line algorithm, a supplementary physics ...

Recent Advances in Development of Polarimetric MODTRAN®6
IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020Efforts have begun on development of MODTRAN7, a polarimetric version of MODTRAN6. A beta-release, modeling single scatter Stokes parameters and linear polarized ground emission is planned for later this year. The basic formalism, single scattering models, and demonstration calculations are presented.

Further comparison of MODTRAN 5 to measured data in the UV band
Proceedings of SPIE, 2014The ability to accurately model background radiation from the sun is important in understanding the operation of missile systems with ultraviolet (UV) guard channels. In theory a missile system’s UV channel detects a target’s silhouette, caused by its ‘negative contrast’ with respect to background UV radiation.

Validation of MODTRAN®6 and its line-by-line algorithm
Journal of Quantitative Spectroscopy and Radiative Transfer, 2017Abstract A new line-by-line (LBL) algorithm has been developed for use within the MODTRAN ® 6 1 atmospheric radiative transfer model. The model computes both emitted and scattered line-of-sight radiances utilizing a spherical refractive geometry package and the DISORT discrete ordinate model to solve the 1-D scattering problem.

MODTRAN®61 Generated Single Scattering Adjacency Function
IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020A new MODTRAN6 output file and post-processing utility has been written to enable generation of single scattering adjacency (aka point spread) functions. The approach relies on Helmholtz reciprocity. A series of MODTRAN single scattering solar radiance calculations are performed to build up a table of adjacency file segment contributions.

HP-MODTRANS: A High performance modular transputer architecture
Microprocessing and Microprogramming, 1993Abstract The main objective of this paper is to present a newly developed high performance transputer architecture called HP-MODTRANS. This dynamically rearrangeable system is organised in a modular way. Each module consists of several transputer clusters operating in parallel, connected toa crossbar switch.
