EMPIRICAL MODEL COMPARISON AND MODEL TUNING FOR ESTIMATING a(CDOM) IN A TROPICAL RESERVOIR IN BRAZIL
(Ieee, 2015-01-01)
The aim of this work was to fit an empirical model for estimating the Colored Dissolved Organic Matter (CDOM) absorption coefficient (a(CDOM)) at 412 nm [a(CDOM)(412)] and 443 nm [a(CDOM)(443)], in Itumbiara reservoir ...
Estimating the CDOM absorption coefficient in tropical inland waters using OLI/Landsat-8 images
(2016-07-02)
Coloured dissolved organic matter (CDOM) is the most abundant dissolved organic matter (DOM) in many natural waters and can affect the water quality, such as the light penetration and the thermal properties of water system. ...
Empirical model comparison and model tuning for estimating aCDOM in a tropical reservoir in Brazil
(2015-11-10)
The aim of this work was to fit an empirical model for estimating the Colored Dissolved Organic Matter (CDOM) absorption coefficient (aCDOM) at 412 nm [aCDOM(412)] and 443 nm [aCDOM(443)], in Itumbiara reservoir (Goiás ...
The aCDOM spatial and temporal distribution analysis in Funil reservoir
(Universidade Estadual Paulista (Unesp), 2017-08-03)
A matéria orgânica dissolvida (DOM) é a componente da água que pode ser usada como indicativo de sua qualidade, pois possui duas fontes: uma alóctone, relacionada com descargas de material terrestre, estando vinculada aos ...
Spatial variability of chromophoric dissolved organic matter in a large floodplain river: Control factors and relations with phytoplankton during a low water period
(John Wiley & Sons Inc, 2016-04)
Chromophoric dissolved organic matter (CDOM) affects ecological processes in freshwater environments. Few studies assessed its spatial variability and relations with phytoplankton in floodplain rivers. Therefore, these ...
Variability in the light absorption coefficients of phytoplankton, nonalgal particles, and colored dissolved organic matter in a subtropical bay (Brazil)
(Hull, 2014-02-20)
This study characterized the variability in magnitudes and spectral shapes of the absorption coefficients of phytoplankton, detritus, and colored dissolved organic matter (CDOM) in a dynamic bay (Santos Bay) in southeastern ...
Bio-optical characterization of offshore NW Mediterranean waters: CDOM contribution to the absorption budget and diffuse attenuation of downwelling irradiance
(Pergamon-Elsevier Science Ltd, 2016-08)
We investigated the peculiar bio-optical characteristics of the Mediterranean Sea focusing on the spectral diffuse attenuation coefficient [Kd (λ)] and its relationship with chlorophyll a concentration (Chl a), complemented ...
Spectral absorption by marine chromophoric dissolved organic matter: Laboratory determination and piecewise regression modeling
(Elsevier Science, 2017-08)
Chromophoric dissolved organic matter (CDOM) is an important light-absorbing component of seawater. Yet spectrophotometric determinations of CDOM absorption from existing laboratory methods differ substantially. Since CDOM ...
Re-parameterization of a quasi-analytical algorithm for colored dissolved organic matter dominant inland waters
(Elsevier B.V., 2016-12-01)
Quasi-Analytical Algorithms (QAAs) are based on radiative transfer equations and have been used to derive inherent optical properties (IOPs) from the above surface remote sensing reflectance (R-rs) in aquatic systems in ...
Modeling the spatio-temporal dissolved organic carbon concentration in Barra Bonita reservoir using OLI/Landsat-8 images
(Springer, 2017-04-01)
Through exchange of heat between the water and the atmosphere inland waters affect climate at the regional scale and play an important role in the global carbon cycle. Therefore, there is a need to develop methods and ...
