Obtaining Inherent Water Optical Properties From Apparent Water Optical Properties

SPIE Proceedings, 1988
Modeling the radiative transfer in the ocean requires the volume absorption coefficient, a, and the volume scattering coefficient, b. These are generally not measured during ocean optical field experiments, rather one typically finds that the apparent optical properties are measured or at least derived from irradiance measurements.

Parameterization of the inherent optical properties of Murchison Bay, Lake Victoria

Applied Optics, 2007
Lake Victoria, Africa's largest freshwater lake, suffers greatly from negative changes in biomass of species of fish and also from severe eutrophication. The continuing deterioration of Lake Victoria's ecological functions has great long-term consequences for the ecosystem benefits it provides to the countries bordering its shores.

Effects of The Inherent Optical Properties On Remotely Sensed Reflectance

2002
Abstract : The long-term goals of this project are to determine how the inherent optical properties and their vertical distribution affect remote sensing. This work includes using two-flow and full radiative transfer models to evaluate the conditions under which subsurface optical structure is detectable, and to develop an inversion model to determine ...

Uniqueness in remote sensing of the inherent optical properties of ocean water

Applied Optics, 2004
We examine the problem of uniqueness in the relationship between the remote-sensing reflectance (Rrs) and the inherent optical properties (IOPs) of ocean water. The results point to the fact that diffuse reflectance of plane irradiance from ocean water is inherently ambiguous. Furthermore, in the 400 < lambda < 750 nm region of the spectrum, Rrs(lambda)

Uncertainties associated to measurements of inherent optical properties in natural waters

Applied Optics, 2010
Monte Carlo simulations are used to explain and quantify the errors in inherent optical properties (IOPs) (absorption and attenuation coefficients) measured using the WET Labs AC-9 submarine spectrophotometer, and to assess correction algorithms. Simulated samples with a wide range of IOPs encountered in natural waters are examined. The relative errors

In situ methods for measuring the inherent optical properties of ocean waters

Limnology and Oceanography, 1995
In situ attenuation (488 and 660 nm), absorption (488, 676, and 750 nm), backscattering (at 488 nm), and stimulated fluorescence were determined as functions of depth in oceanic and coastal waters off Oregon, using both commercial instruments and recently developed prototypes.

Determination of inherent optical properties of Lake Ontario coastal waters

Applied Optics, 1979
Two optical models (one based upon Monte Carlo simulations of the solutions of the radiative transfer equations and one based upon exponential/quasi-single scattering simulations) relating the apparent and inherent optical properties of natural water masses are utilized in conjunction with directly measured values of the irradiance attenuation ...

Airborne LIDAR as a tool for estimating inherent optical properties

SPIE Proceedings, 2012
LIght Detection and Ranging (LIDAR) systems have been used most extensively to generate elevation maps of land, ice and coastal bathymetry. There has been space-, airborne- and land-based LIDAR systems. They have also been used in underwater communication.

Toward closure of the inherent optical properties of natural waters

Journal of Geophysical Research: Oceans, 1995
A fundamental relationship of inherent optical properties (IOP) is that the beam attenuation coefficient is the sum of the volume absorption and scattering coefficients (c = a + b). A relative calibration of a set of instruments can be provided using this IOP closure equation.
