南海海域叶绿素浓度分布特征的卫星遥感分析

SATELLITE REMOTELY-SENSED ANALYSIS OFDISTRIBUTION CHARACTERS OF CHLOROPHYLLCONCENTRATION IN SOUTH CHINA SEA

介绍了第二代海洋水色传感器 SeaWiFS资料的特点及其基本处理方法、海水叶绿素浓度提取方法。对南海海域表层海水叶绿素浓度分布的时空变化特征及其与营养物质和南海环流的关系进行了初步分析。

This paper introduces the properties of satellite data obtained by Sea-viewingWide Field--of--view Sensor (SeaWiFS), the basic method for the data processing and thealgorithm for determination of chlorophyll concentration. The results of chlorophyllconcentration retrieved by application of the default algorithm of SeaWiFS Data AnalysisSystem (SeaDAS) are in good agreement with the sea truth data. The temporal and spa-tial variations of ch1orophyll concentration distribution in the surface layer of the SouthChina Sea and their relationship with the nutrients and the circulation system are ana-lyzed.
