| Abstract |
A hydro-optical algorithm based on reflectance at 555nm has been used in the past for suspended particulate matter concentrations (SPM) retrieval from SeaWiFS over the Belgian coastal (case II) waters in Southern North Sea. The extra spectral resolution of MERIS offers the possibility of improvements, though necessitates algorithm recalibration. This study presents the calibration of the hydro-optical model used to derive SPM from MERIS reflectance for Belgian coastal waters. The model is based simply on reflectance at one suitably-chosen band. Regression analysis is carried out for seaborne measurements of reflectance and SPM taken over our region of interest, to determine and calibrate the bands best suited for SPM detection. Sensitivity of the method to errors is studied. |
