Remote-sensing reflectance in the Beaufort and Chukchi seas: observations and models

Applied Optics, 2003
Two semianalytical remote-sensing reflectance models were evaluated and validated by use of bio-optical data collected in the Beaufort and Chukchi seas. Both models were efficient at retrieving chlorophyll concentration, phytoplankton absorption coefficients,and particulate backscattering coefficients.

Retrieval of chlorophyll from remote-sensing reflectance in the China seas

Applied Optics, 2000
The East China Sea is a typical case 2 water environment, where concentrations of phytoplankton pigments, suspended matter, and chromophoric dissolved organic matter (CDOM) are all higher than those in the open oceans, because of the discharge from the Yangtze River and the Yellow River. By using a hyperspectral semianalytical model, we simulated a set

Characterization of the Fluorescence Peak on Remote Sensing Reflectance For Different Conditions of Lakegarda

2018 9th Workshop on Hyperspectral Image and Signal Processing: Evolution in Remote Sensing (WHISPERS), 2018
The presence of phytoplankton in the oceans and freshwaters basins provides relevant ecological indications about water quality. Its abundance influences the interaction between the solar light and the water body, which in turn can be detected by remote sensing techniques.

Atmospheric Effects On Remote Sensing Of Surface Reflectance

SPIE Proceedings, 1984
This paper reviews the atmospheric effects on remote sensing of surface reflectance. The scattering and absorption of sunlight by atmospheric molecules and aerosols affects the quality of images of the surface remotely sensed from satellites and aircrafts.

The Application of Reflected GPS Signals to Ocean Remote Sensing

Remote Sensing of Environment, 2000
Abstract The L-band broadcast signal from the Global Positioning System (GPS) reflected off of the sea surface is under study for use as a ocean, coastal, and wetlands remote sensing tool. The reflected signal from a given GPS satellite is cross-correlated with the pseudorandom noise code uniquely identifying that satellite.

Small-sized remote sensing reflectance meter

Fundamental and Applied Hydrophysics
A small-sized spectroradiometer (SSR) developed at the Shirshov Institute of Oceanology of the Russian Academy of Sciences based on a miniature AIOX 2000–02 spectrometer for deck measurements of the spectral remote sensing reflectance Rrs(λ), the parts of which are mainly made by 3D printing, is described.

Remote sensing of photosynthetic processes by the Photochemical Reflectance Index (PRI)

2006
The Photochemical Reflectance Index (PRI) has been proposed as a tool for the estimation of leaf and canopy light-use efficiency and photosynthesis from remote-sensing data. The application of the index is based on more than fifteen years of spectroscopic studies at the leaf level, which support it with a sound physiological basis. In the present study,

Estimation of the remote-sensing reflectance from above-surface measurements

Applied Optics, 1999
The remote-sensing reflectance R(rs) is not directly measurable, and various methodologies have been employed in its estimation. I review the radiative transfer foundations of several commonly used methods for estimating R(rs), and errors associated with estimating R(rs) by removal of surface-reflected sky radiance are evaluated using the Hydrolight ...

Applying narrowband remote-sensing reflectance models to wideband data

Applied Optics, 2009
Remote sensing of coastal and inland waters requires sensors to have a high spatial resolution to cover the spatial variation of biogeochemical properties in fine scales. High spatial-resolution sensors, however, are usually equipped with spectral bands that are wide in bandwidth (50 nm or wider).
