Atmospheric optical properties play an important role in many problems, such as military-systems analysis, climatology, pollution monitoring, global energy balance, etc. Unfortunately, atmospheric effects from molecular absorption/ scattering, aerosol absorption/scattering, clouds (ice and water), solar scattering, path refraction and surface ...

Multiple Scattering in MODTRAN®
2019MODTRAN® has the option to employ one of several multiple-scattering algorithms while performing MS calculations. Their particular use depends on the accuracy desired and the computation-time tolerance. The previous chapter provided some rules of thumb for MS considerations and selecting the appropriate algorithm. This chapter will discuss MODTRAN’s MS

Applying the OSS radiative transfer method to MODTRAN
SPIE Proceedings, 2006The Optimal Spectral Sampling (OSS) method models band averaged radiances as weighted sums of monochromatic radiances. The method is fast and accurate and has the advantage over other existing techniques that it is directly applicable to scattering atmospheres.

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.

Surface Reflectance in MODTRAN®
2019Multi-spectral and hyperspectral remote-sensing technologies have been developed over the last thirty years for a variety of applications. These technologies cover the entire optical spectrum, ranging from visible to NIR (VNIR), SWIR, MWIR, and LWIR light. The most mature sensor technology currently covers the VNIR–SWIR portion of the optical spectrum,

EOSPEC: a complementary toolbox for MODTRAN calculations
SPIE Proceedings, 2016For more than a decade, Defence Research and Development Canada (DRDC) has been developing a Library of computer models for the calculations of atmospheric effects on EO-IR sensor performances. The Library, called EOSPEC-LIB (EO-IR Sensor PErformance Computation LIBrary) has been designed as a complement to MODTRAN, the radiative transfer code ...

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

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.

Sensitivity study of Infrared Difference Dust Index by using MODTRAN
2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016Infrared Difference Dust Index (IDDI) is often used as a satellite dust product to detect the change of mineral dust aerosols in the atmosphere. And aerosol optical depth (AOD) is also a main measurement for mineral dust aerosol. To qualify dust loading on the regional or global scale, it is very necessary to understand the relation between IDDI and ...

MODTRAN Cloud and Multiple Scattering Upgrades with Application to AVIRIS
Remote Sensing of Environment, 1998Abstract Recent upgrades to the MODTRAN atmospheric radiation code improve the accuracy of its radiance predictions, especially in the presence of clouds and thick aerosols, and for multiple scattering in regions of strong molecular line absorption.
