主流的透明度半分析反演算法在渤、黄海的适用性评价
Validation of Main Semi-analytical Retrieval Algorithms of Transparency in the Bohai and Yellow Sea
摘要
Abstract
Transparency,usually characterized by the Secchi disk depth ZSD ,is a basic parameter of optical properties of ocean water.Main semi-analytical algorithms for transparency estimation are validated based on 407 in-situ data in the Bohai Sea and Yellow Sea (the measured ZSD is in the range of 0.1 ~18.0 m).The semi-analytical algorithms include those based on remote sensing reflectance at 709 nm,at 560 nm and the quasi-analytical algorithm (QAA)of the inher-ent optical properties.Comparisons between Secchi depth retrievals from semi-analytical algorithms and in-situ measure-ments show that these three algorithms are not applicable to the Bohai Sea and Yellow Sea.The root mean square error (RMSE)is larger than 2.2 m and the average absolute percentage difference (APD)is larger than 68%.The semi-an-alytical algorithm based on remote sensing reflectance at 560 nm shows a better performance with RMSE of 2.2 ~4.6 m and APD of 68.0 ~86.7%,compared to the algorithms based on remote sensing reflectance at 709 nm (RMSE of 10.8~15.9 m and APD of 70.4 ~1 16.3%)and QAA (RMSE of 2.8 ~4.4 m and APD of 73.9 ~1 15.1%).关键词
