Evaluation of Atmospheric Correction Algorithms for Sentinel-2-MSI and Sentinel-3-OLCI in Highly Turbid Estuarine Waters
(Multidisciplinary Digital Publishing Institute, 2020-04)
The present study assesses the performance of state-of-the-art atmospheric correction (AC) algorithms applied to Sentinel-2-MultiSpectral Instrument (S2-MSI) and Sentinel-3-Ocean and Land Color Instrument (S3-OLCI) data ...
Performance analysis of the C2RCC processor in estimate the water quality parameters in inland waters using OLCI/Sentinel-3A images
(2018-10-31)
Remote sensing can be a powerful tool for long-term spatial and temporal water quality monitoring if proper sets of algorithms are available. To estimate optically significant substances (OSS) by satellite images the ...
Estimation of chlorophyll-a concentration from optimizing a semi-analytical algorithm in productive inland waters
(2018-02-01)
The high nutrient concentrations coming from non-point and point pollution have been linked to algae blooms, especially in hydroelectric plant reservoirs, due to higher residence time compared to rivers. The monitoring of ...
High performance of chlorophyll-a prediction algorithms based on simulated OLCI Sentinel-3A bands in cyanobacteria-dominated inland waters
(2018-07-15)
In this research, we have investigated whether the chlorophyll-a (chl a) retrieval algorithms based on OLCI Sentinel-3A bands are suitable for cyanobacteria-dominated waters. Phytoplankton assemblages model optical properties ...
Effect of Prompt Particle Events on OLCI Ocean Color Imagery in the South Atlantic Anomaly: Detection and Removal
(Institute of Electrical and Electronics Engineers, 2018-10)
It has been found that cosmic rays and massive charged particles trapped in the magnetosphere or arriving from the sun might produce spike noise over the dark offset signal coming from charge-coupled devices (CCDs) on optic ...

Remote sensing of chlorophyll-a concentration based on absorption coefficients in Ibitinga reservoir
(Universidade Estadual Paulista (Unesp), 2018-03-23)
O presente estudo objetivou estimar as concentrações de clorofila-a (Chl-a) no reservatório da usina hidroelétrica de Ibitinga (RHI), localizado no Rio Tietê, estado de São Paulo, Brasil, por meio de coeficientes de absorção ...
Estimating the optical properties of inorganic matter-dominated oligo-to-mesotrophic inland waters
(2018-04-09)
Many studies over the years have focused on bio-optical modeling of inland waters to monitor water quality. However, those studies have been conducted mainly in eutrophic and hyper-eutrophic environments dominated by ...
