Abstract

1996 marks the revival of the production of visible channel imagery of the ocean with the planned launches of Japan's ADEOS Ocean Color Temperature Sensor (OCTS), SeaWiFS, and the EOS MODIS-N, with launch dates 1996, 1997 and 1998 respectively. At least three other missions are at various stages of planning. The missions will initiate a continuous global time series of ocean color data that should extend well into the next century. The classification of water types and application of pigment retrieval algorithms specific to those water types may increase the accuracy of retrieved pigment concentrations. The aim is to develop a pigment concentration retrieval algorithm tunes to local oceanic conditions. Investigation of the effects of the physical and optical properties of the ocean on the water- leaving radiance, and the development of an inversion scheme for measurement of those physical and optical properties may be achieved through modeling. This approach also aids the design of validation programs. A simple relationship has been fond for predicting the reflectance of the ocean for different optical properties. The applicability of this relationship to chlorophyll concentration retrieval is being investigated. A multiple channel reflectance inversions has been used to derive pigment concentrations from model results. Preliminary results show that the scheme is sensitive to uncertainty in optical properties of water constituents. The scheme does however provide some indication of the confidence limits applicable to the retrieved concentration.
