Inverse estimation of multi-substance concentration based on a radiative transfer theory for remote-sensing analysis of coastal and ocean subsurface properties

A new method based on a four-flux radiative transfer model has been developed to estimate multi-substance concentration even in red tide or blue tide areas. In this method, the concentration of the multi-substance concerned can be obtained simultaneously from the satellite image data by solving a non-linear inverse problem specified with the optical characteristics of each substance as pre-known parameters. The fundamental performance of the method was examined by applying it to numerically simulated image data.
