Abstract:
Complex oceanic environment(OE) is a typical scene in space photoelectric detection. Ocean surface albedo(OSA) from visible to far-infrared is of great importance to study of ocean atmospheric transfer and background radiative properties. However, the OSA in China Sea areas was less studied at present. This study built a fast parameterized OSA application model on the basis of statistical analysis of multiple-satellite measured long-time OE parameters. The new model took chlorophyll concentration of sea water, aerosol optical depth, ocean surface wind speed and solar illuminating angles into account. The fast parameterized application model of sea surface albedo was established, and the spectral curves of 0.4-14 micron sea surface albedo in the South China Sea, the East China Sea, the Yellow Sea and Bohai were obtained, and spatiotemporal features of OSAs were analyzed. These OSA spectrum provides fundamental data support for space photoelectric engineering applications above seas.
