Hyperspectral Simulation And Recovery Of Submerged Targets In Turbid Waters, Charles R. Bostater
Hyperspectral Simulation And Recovery Of Submerged Targets In Turbid Waters, Charles R. Bostater
Ocean Engineering and Marine Sciences Faculty Publications
Modeled hyperspectral reflectance signatures just above the water surface are obtained from radiative transfer models to create synthetic images of targets below the water surface. Images are displayed as 24 bit RGB images of the water surface using selected channels. Example model outputs are presented in this paper for a hyperspectral Monte Carlo and a hyperspectral layered analytical iterative model of radiative transport within turbid shallow water types. Images at the selected wavelengths or channels centered at 490, 530 and 680 nm suggests the two models provide quite similar results when displayed as RGB images. The techniques are demonstrated to …
Synthetic Image Generation Of Shallow Water Using An Iterative Layered Radiative Transfer Model With Realistic Water Surface Waves, Charles R. Bostater Jr., Lisa Huddleston, Luce Bassetti
Synthetic Image Generation Of Shallow Water Using An Iterative Layered Radiative Transfer Model With Realistic Water Surface Waves, Charles R. Bostater Jr., Lisa Huddleston, Luce Bassetti
Ocean Engineering and Marine Sciences Faculty Publications
Modeled hyperspectral reflectance signatures just above the water surface are obtained from an analytical-based, iterative radiative transport model applicable to shallow water types. Light transport within the water body is simulated using a fast, accurate radiative transfer model that calculates the light distribution in any layered media. A realistic water surface is synthesized using empirically-based spectral models of the ocean surface to generate water surface waves. Images are displayed as 24 bit RGB images of the water surface using selected channels from a synthetic hyperspectral image cube. The selected channels are centered at 490, 530 and 676 nm. Hyperspectral image …
Data Assimilation Of Avhrr And Modis Data For Land Base Initialization And Boundary Conditions In The Utc-M Atmospheric Boundary Layer Sea-Breeze Model Of Space Coast Florida, Charles R. Bostater Jr., Jerome A. King, Lisa H. Huddleston, Luce Bassetti
Data Assimilation Of Avhrr And Modis Data For Land Base Initialization And Boundary Conditions In The Utc-M Atmospheric Boundary Layer Sea-Breeze Model Of Space Coast Florida, Charles R. Bostater Jr., Jerome A. King, Lisa H. Huddleston, Luce Bassetti

The purpose of this paper is to present results of simulations of the Florida Tech UTC-M sea-breeze model22 with the addition of a simplified atmospheric downwelling radiation subroutine1,4 combined and a thermal inertia subroutine17,19,20 into the atmospheric planetary boundary layer model, in order to calculate time dependant heat flux boundary conditions at the air-land boundary that are derived from satellite data from AVHRR and MODIS sensors. The improved UTC-M planetary boundary layer model with this thermal sub-model subroutine is used to demonstrate the use of thermal inertia to help estimate heat fluxes at the land-air interface which in turn influences …

Submerged aquatic vegetation (SAV) is an important indicator of freshwater and marine water quality in almost all shallow water aquatic environments. Throughout the world the diversity of submerged aquatic vegetation appears to be in decline, although sufficient historical data, of sufficient quantitative quality is lacking. Hyperspectral remote sensing technology, available from low altitude aircraft sensors, may provide a basis to improve upon existing photographic regional assessments and monitoring concerned with the aerial extent and coverage of SAV. In addition, modern low altitude remote sensing may also help in the development of environmental satellite requirements for future satellite payloads. This paper …
