In situ evidence of non-zero reflectance in the OLCI 1020nm band for a turbid estuary
(Elsevier Science Inc, 2012-02)
A spectroradiometer able to measure up to 2500nm has been used to measure the reflectance for the Ocean and Land Color Instrument (OLCI) 1020nm band. In July and October 2010 two measurement campaigns were organized at the ...
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 ...
Evaluation of the suitability of MODIS, OLCI and OLI for mapping the distribution of total suspended matter in the Barra Bonita Reservoir (Tietê River, Brazil)
(2016-10-01)
The objective of this work was to evaluate the suitability of three remote sensors, namely, the Moderate Resolution Imaging Spectroradiometer (MODIS), the Operational Land Imager (OLI), and the Ocean Land Color Instrument ...
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 ...
Evaluación de productos satelitales de clorofila-a derivados de Aqua-MODIS y OLCI en la sección norte de la plataforma continental Argentina
(Universidad Nacional de Mar del Plata, 2020)
La clorofila-a (Chl-a) satelital se utiliza como proxy para estudiar la dinámica delfitoplancton en los ambientes marinos con una alta cobertura espacial y temporal. Elobjetivo del presente estudio es evaluar el desempeño ...
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 ...
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 ...
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 ...
Biophysical matter in a marine estuary identified by the Sentinel-3B OLCI satellite and the presence of terrestrial iron (Fe) nanoparticles
