摘要
利用2011年黄河调水调沙期间测量的45组表面光谱和悬浮物浓度数据,分析了黄河口海域不同悬浮物浓度水体的光谱特征.采用Rrs(709)/Rrs(443)和Rrs(709)/Rrs(560)的波段组合形式,由实测数据建立了针对MERIS的悬浮物浓度反演模型.基于独立数据的模型精度检验结果表明,模型反演结果的相关系数为0.87,平均相对误差为28.3%.
During water and sediment regulation of Yellow River in 2011,45 groups of surface spectral and suspended matters concentration data were obtained. Based on these data, spectral characteristics of Yellow River estuary waters is analyzed. A suspended matters retrieval model for MERIS data is estab- lished. We find that the combination of Rrs(709)/Rrs(443) and Rrs(709)/Rrs(560) is superior to other bands' combinations and has high retrieval accuracy. The correlation coefficient derived from this model is 0.87, the mean relative error of the model test result is 28.3 %.
