Objective
To explore the spectral data of future satellite born advanced ocean colour sensors by theoretical and experimental studies.
Progress to end 1991
New activity proposed from 1991
Detailed description of work foreseen in 1992 (expected results)
Ocean colour studies from space have mainly used the data of the 4 channels of the Coastal Zone Color Scanner (CZCS). The sensors to be launched within the next years (SEAWIFS, MERIS, ROSIS, MODIS) will provide precise and extended spectral information of the Ocean. For the real use of this advanced information a better understanding of the optical properties of coastal and oceanic water is needed. This is of particular importance for practical applications in coastal areas with different sediment content of the water, optical stratification of bottom reflectance. The study is based on theoretical radiation modelling and verification by field measurements. The following actions are proposed :
- Development of a multi layer radiation transfer model for the entire visible and NIR spectral range (400-900 nm).
- Creation of a spectral a data base for optically active materials (OAM) as phytoplankton species, sediment and dissolved organic matter (DOM) using literature and laboratory archives.
- Bioptical measurements in collaboration with local research institutes using appropriate new techniques and instruments to build up the data base for an adequate validation of the radiation model.
