Abstract

Present study investigated the sentinel-3 OLCI (Ocean and Land Colour Instrument) sensor retrieved chlorophyll and total suspended matter (TSM) validation. The in-situ chlorophyll and TSM concentration ranged from 0.14 μgl−1 to 9.36 μgl−1 and 0.15 mgl−1 to 39.27 mg l−1, respectively. Sentinel-3 derived chlorophyll (OC4Me) and TSM (TSM NN) algorithm value oscillated from 0.15mg m3 to 19.21mg m3 and 0.107 g m3 to 41.88g m3. TSM concentration of sentinel-3 retrieved value showed 45% underestimation and chlorophyll 40% over estimation. The present study revealed that more attention and improved methodology for data collection and analyses need to be applied in order to develop remote sensing product that perform well in optically complex water.
