Comparison of skylight polarization measurements and MODTRAN-P calculations
Journal of Applied Remote Sensing, 2011Increased use of polarization in optical remote sensing provides motivation for a study of instruments and methods that can be used to test and validate polarized atmospheric radiative transfer codes and simulation tools. An example comparison of measured skylight polarization and calculations from a preliminary version of the polarized MODTRAN ...

Cluster versus grid for operational generation of ATCOR’s modtran-based look up tables
Parallel Computing, 2008A critical step in the product generation of satellite or airborne earth observation data is the correction of atmospheric features. Due to the complexity of the underlying physical model and the amount of coordinated effort required to provide, verify and maintain baseline atmospheric observations, one particular scientific modelling program, modtran,

Building a J-MASS IR environment player using MODTRAN
Proceedings of the IEEE 1996 National Aerospace and Electronics Conference NAECON 1996, 2002This paper describes methodology incorporating the MODTRAN infrared propagation model as a player in the Joint Modeling and Simulation System (J-MASS). MODTRAN, developed by the Air Force Geophysics Directorate of Phillips Laboratory, provides a medium resolution model of absorption, scattering, and background IR effects widely used in modeling and ...

MODTRAN-based retrieval of column water vapor from solar transmittance
SPIE Proceedings, 2004The Remote Sensing Group of the Optical Sciences Center at the University of Arizona has a history of collecting ground-based atmospheric data in support of calibration/validation and for atmospheric correction. This work has included the determination of columnar water vapor based on measurements of direct solar irradiance. In the past, the conversion

Applied Optics, 1996
Passive infrared remote detection of hazardous gases, vapors, and aerosols is based on the difference, Δ T, between the air temperature of the threat vapor cloud and the effective radiative temperature of the background. In this paper I address the problem of detection with a low-angle-sky background.

Polarized MODTRAN 3.7 applied to characterization of ocean color in the presence of aerosols
SPIE Proceedings, 2002The color of the ocean and estuarine waters are key indicators of pollutants as well as biological phenomenon. However atmospheric aerosols can be produce a significant bias in the observations. Of particular importance is dust from the Sahara and Gobi Deserts on the Atlantic and Pacific Ocean photometric observations.

MODTRAN® scattering: Extracting spherical-refractive path contributions from plane-parallel disort
2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017The well-established and extensively validated atmospheric radiative transfer model MODTRAN®1 is widely used by the remote sensing community to define the mapping from surface spectral reflectance to solar scatter radiance as a function of atmosphere definition.

A new MODTRAN-based thermal model for accelerating PLUME TRACKER volcanic emission analysis
2014 6th Workshop on Hyperspectral Image and Signal Processing: Evolution in Remote Sensing (WHISPERS), 2014Plume Tracker (PT), formerly MAP_SO2, is robust, extensively validated, analyst driven software for retrieving gaseous emissions from volcanic releases. While Plume Tracker provides very accurate results, analyzing multispectral imagery typically takes several days of analyst time.

Electro optical design for a space camera based on MODTRAN data analysis
SPIE Proceedings, 2014Electro-Optical design of a push-broom space camera for a Low Earth Orbit (LEO) remote sensing satellite is discussed in this paper. An atmosphere analysis is performed based on ModTran algorithm and the total radiance of visible light reached to the camera entrance diameter is simulated by Atmosphere radiative transfer software PcModWin. Simulation is

Impact of MODTRAN�5.1 on Atmospheric Compensation
IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008MODTRANreg Version 5.1 includes many new capabilities tailored to enhance and facilitate atmospheric compensation. For the thermal region, the new 0.1 cm-1 band model provides the finer spectral resolution required for analysis of state-of-the-art long-wave and mid-wave hyper- and ultraspectral imagers (e.g. AIRS).
