Radiance multiply scattered from clouds and thick aerosols is a significant component in the short wave IR through the visible region of the electro-optical (EO) spectrum. In MODTRAN, until very recently, multiple scattering predictions could not vary with the azimuth of the line-of-sight (LOS), although the single scattering component of the radiance ...

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.

Radiometric images taken in mid-wave and long-wave infrared bands are used as a basis for validating a sea surface bidirectional reflectance distribution function (BRDF) being implemented into MODTRAN 5 (Berk et al. [Proc. SPIE5806, 662 (2005)]). The images were obtained during the MIRAMER campaign that took place in May 2008 in the Mediterranean Sea ...

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

Comparison of night sky spectral radiance measurements with MODTRAN and LOWTRAN 7 predictions
SPIE Proceedings, 1992Measurements of the night sky spectral radiance were made with a Fourier Transform spectrometer at angles between 1 degree(s) and 90 degree(s) elevation over the wavelength region from 2.5 to 10.0 micrometers . The LOWTRAN 7 and MODTRAN computer models were used to predict the path radiance from ground to space for the same angles as the measurements ...

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 ...

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 ...
