AN SEMI-ANALYTIC MERIS OCEAN COLOR REMOTE SENSING MODEL OF BOHAI SEA AND ITS RETRIEVAL ABILITY ANALYSIS

摘要

Bohai is a semi-close sea of China, which is confrontedrnwith serious problems on resource, environment andrnecology. To match ENVISAT MERIS spectral band,rnthis paper explores a semi-analytic ocean color retrievalrnmodel based on optimization method and Bohai in-siturndata by putting forward two models: forward modelrnwhich simulates remote sensing reflectance with oceanrncolor constituents concentration and inversion modelrnwhich retrieves the ocean color constituentsrnconcentration with seawater remote sensing reflectance.rnThe results show that the simulation model withrnoptimized parameters is more applicable to the researchrnarea, and the inversion model is feasible and robustrnalthough its practicability needs further validation.
