传统的海水透明度监测方法是利用船舶等进行实测。由于船测本身固有的缺点,满足不了当前对海洋要素大范围、快速、实时监测的需求,必须结合卫星、航空遥感等手段,进行立体监测。文章以海水透明度为突破口,开展中国海透明度的卫星遥感监测。结果表明,利用卫星遥感技术反演海水透明度精度可以达到相对平均误差22.6%,在中高透明度海区,具有更高的反演精度。利用建立的海水透明度遥感反演算法和SeaWiFS卫星遥感数据,制作了两年的中国海透明度遥感产品数据集,并利用该产品,对中国海透明度的时空变化规律进行了遥感分析。
The traditional method of monitoring water transparency is the in-situ measurement by using ship et al. However, this method can not satisfy the large area, quick and real-time monitor demand of the ocean element, because of the inherent shortcoming of the in-situ measurement. It must combine the remote sensing method to fulfill the stereo monitor. This paper puts water transparency as the breakthrough, and studys the water transparency monitoring by using satellite remote sensing. The result shows that the inverse relative error is 22.6% by using remote sensing, and it is even better for clear water. A collection of water transparency products of the China sea for two years is generated by using the inverse algorithm and SeaWiFS data sets. Also, the analysis of the distribution and fluctuation patterns of water transparency in the China sea is carried out by using the established collection.
