PARTICULATE BACKSCATTERING RETRIEVAL FROM REMOTELY-SENSED TURBIDITY IN VARIOUS COASTAL AND RIVERINE TURBID WATERS

摘要

The semi-empirical algorithm of [1] for the estimationrnof turbidity (T) from marine reflectance (ρ_w) isrncalibrated and validated using a large dataset of in siturnmeasurements collected in various waters, for use withrnany ocean colour hyperspectral sensor, and withrnSentinel-2, Landsat 8 and Pléiades spectral bands. Thernrelationship between particulate backscatteringrncoefficient (b_(bp)) and side-scattering (T) is investigatedrnthrough simulation of Fournier-Forand phase functions,rnassuming variable particles size and composition, andrnthrough T and b_(bp) in situ measurements in clear tornextremely turbid waters.
