利用MODIS图像同时反演水色三要素的方法研究
Model on the chlorophyll, suspended matter and gelbstoff concentrations based on MODIS data
摘要
Abstract
In order to establish the mode of the concentration of three elements ( chlorophyll-a, suspended matter and gelbstoff) , several neural network models were established to retrieve the three element concentration simultaneously from remote sensing reflectance based on moderate-resolution imaging spectroradiometer( MODIS) data. The measured ocean color data was obtained in Pearl River esturay in 2003 and 2004. According to the model, the map of the concentrations of the three elements was drawn and its forming reason was analyzed. The study demonstrates that the model can get the better prediction accuracy based on the reflectance at band combination of 443nm, 488nm, 531nm, 351 run, 667run, 678nm and 748nm than the other band combinations. The algorithm has good accuracy.关键词
