Retrieval of Chlorophyll a, suspended solids, and colored dissolved organic matter in Tokyo Bay using ASTER data

In the present investigation, we implemented the NN method in the analysis of ASTER data of Tokyo Bay, as a case study in the coastal waters in order to demonstrate the usefulness of remote sensing with high spatial resolution. After validation of the NN using simulated data sets and a field data set observed from a ship, estimation of the concentration of TSS and Chl-a was reasonably accurate. However, in the case of CDOM, the result is not reliable. Disadvantages of the NN method are discussed in this paper.
