A Linear Retrieval Algorithm For Retrieval Of Three Components Of Case 2 In Coastal Oceans Of China

Retrieval of concentrations of total suspended matter, chlorophyll, and CDOM constitutes a concern in remote sensing of Case 2 ocean water. Based on former research achievements, this study established a linear model of Reflectance of Remote Sensing (Rrs) of Case 2 coastal water of China. Experimental simulation was also carried out. The results show that the concentrations of TSM and chlorophyll are relatively less sensitive to the model errors, while CDOM is more sensitive. Remote sensing data of Yellow Sea and East Sea of China provided by National Satellite Ocean Application Service of China were applied in this paper. Spectral profiles calculated from the linear model show the similar trend with measured results form the Yellow Sea and the East Sea. The linear relationships between band 443 nm and band 490, and 5 10 and 555 nm match well with real situations. The spectral curves of TSM and chlorophyll in our model yield some useful information for calculating the concentration of CDOM.
