摘要

ESA’s upcoming satellite Sentinel-3 will provide continuity for altimeter and optical medium spatial resolution imagery, with high temporal resolution. Sentinel-3 will carry the OLCI sensor (Ocean and Land Color Instrument), a multispectral medium resolution instrument planned for Ocean Color observation designed to minimize sun-glint and composed with 21 spectral bands. In comparison to the latter sensors, Sentinel-3 includes two new bands in the NIR spectral domain for the aerosol retrieval, required to perform an accurate atmospheric correction.rnThe objective of this study is to evaluate the performance of the upcoming multispectral sensor by comparing OLCI reflectance, obtained from hyperspectral satellite imagery processing, with synchronous MERIS data. Selected satellite observations, acquired on 11/01/2012 over northern Adriatic Sea basin, show turbidity patterns due to wave-rngenerated resuspension of sediments during intense wind stress conditions.
