长江口及邻近海域表层悬浮泥沙与漫衰减系数的遥感估算
发布时间：2021-01-31 12:21
水质量是衡量影响河口海岸区域生态环境的重要指标。而悬浮泥沙浓度和漫衰减系数均是影响水质量的关键参数之一。但是实地监测或者设立台站耗时耗力成本巨大,且测量数据区域代表性尚待考究,亟需准确低廉的大面遥感监测补充。准确性和时效性是实施遥感监测的前提,本文围绕实测数据和卫星遥感图像处理两个最主要的环节,对遥感监测悬浮泥沙和漫衰减系数的准确性展开深入研究,并探讨了时效性解决方案。本文第二部分围绕实测数据获取与处理过程,介绍了海洋调查船测量水体光学性质过程及所用仪器,总结和对比了6种光谱数据的获取和处理模型,创新地发展了适合浑浊水体的生物光学模型,总结对比了28种适合浑浊水体的遥感反演算法。准确的实测数据至少可以满足两方面的需求：1)生物光学模型建立和验证需要准确地实测水体光学性质,例如固有光学量（IOPs）、几何条件等等；2)大气校正之后的卫星信号转化为准确的遥感反射率（Rrs（λ））等。本文简单介绍了海洋遥感实地调查过程中常用的几种仪器和操作过程中应注意的问题。本文总结对比了Mobley model （MM）, Whitlock model （M）, Ruddick-Mobley mode1（...
