In situ evidence of non-zero reflectance in the OLCI 1020nm band for a turbid estuary

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 Scheldt river to collect reflectance spectra and corresponding Total Suspende...

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 turbidity. A wide range of TSM concentration was covered from 15 to 402mgL -1. The measurements show a significant increase in reflectance between 950 and 1150nm, corresponding to a decrease in the pure water absorption coefficient. A high correlation was observed between the reflectance at 1020 and 1071nm and TSM concentration.
