渤黄海水体漫衰减系数的遥感反演
A Novel Remote Sensing Algorithm for Estimating Dif-fuse Attenuation Coefficient in the Bohai Sea and Yellow Sea
摘要
Abstract
[Objective]Considering the complex characteristics of the Chinese Seas,a novel,rath-er high accuracy and stable algorithm was built to suit for both the clear water body and the turbid water body.[Methods]Based on in situ data around the coastal regions of China from January 2000 to February 2004,semi-analytical and empirical algorithms were developed for de-riving diffuse attenuation coefficient in turbid and clear waters,respectively.Based on the meth-od of weighting,these two algorithms were combined as a new algorithm.[Results]The retrieval result of the new combined algorithm shows that the correlation coefficient(R2 )of the algorithm reaches 0.891,and the RMSE and the MAPE are 0.543 m-1 and 26.77%,respectively. Furthermore,the precision and the stability of the algorithm are relatively good in model vali-dation.[Conclusion]The new algorithm is suit-able for the retrieval of Kd(490)in Bohai Sea and Yellow Sea.关键词
