REMOTE SENSING INVERSION ALGORITHM OF SUSPENDED PARTICULATE MATTER CONCENTRATION BY USING MERIS SATELLITE DATA IN THE YELLOW RIVER ESTUARY

摘要

In this paper, based on the in situ SPM (Suspendedrnparticulate matter) concentrations which containsrnextremely turbid water (SPM ranging from 4.48 torn2301 mg/L) and remote sensing reflectance spectralrndata obtained from the Yellow River Estuary in July,rnNovember and December of 2011, the statisticalrnretrieval algorithm for the concentration of SPM isrndeveloped to MERIS sensors. The algorithm are testedrnby other independent dataset, the results show that therndetermination coefficient of in-situ and retrieved SPMrnis 0.95(Logarithm coordinates) and the AbsoluternPercentage Difference (APD) is 30.7% (Linearrncoordinates). Finally, the map of SPM distribution inrnthe Yellow River estuary for October 16, 2011, isrngiven, and the spatial distribution characteristics arernpreliminarily analyzed.
