River Flow Monitoring by Sentinel-3 OLCI and MODIS: Comparison and Combination [PDF]
Remote Sensing, 2020 The monitoring of rivers by satellite is an up-to-date subject in hydrological studies as confirmed by the interest of space agencies to finance specific missions that respond to the quantification of surface water flows. We address the problem by using multi-spectral sensors, in the near-infrared (NIR) band, correlating the reflectance ratio between a

In situ evidence of non-zero reflectance in the OLCI 1020 nm band for a turbid estuary
Remote Sensing of Environment, 2012 Abstract A spectroradiometer able to measure up to 2500 nm has been used to measure the reflectance for the Ocean and Land Color Instrument (OLCI) 1020 nm band. In July and October 2010 two measurement campaigns were organized at the Scheldt river to collect reflectance spectra and corresponding Total Suspended Matter (TSM) concentration and ...

Development of VIIRS-OLCI chlorophyll-a product for the coastal estuaries
Frontiers in Marine ScienceCoastal waters require monitoring of chlorophyll-a concentration (Chl-a) in a wide range of Chl-a from a few mg/m3 to hundreds of mg/m3, which is of interest to the fisheries industry, evaluation of climate change effects, ecological modeling and detection of Harmful Algal Blooms (HABs).
