Abstract :
The MERIS-derived remote sensing reflectance (Rrs) ratios Rrs(708)/Rrs(665) and Rrs(753)/[Rrs(665)-Rrs(708)] have been successfully used to estimate chlorophyll concentration in diverse turbid coastal waters of US. Here, the response of these two optical proxies with respect to changes on concentration of suspended particulate matter (CSPM) is evaluated in the St. Lawrence Estuary for the first time. Preliminary results showed that Rrs(708)/Rrs(665) had a better performance (RMSE = 3.06) than Rrs(753)/[Rrs(665)-Rrs(708)] (RMSE = 7.76) for estimating CSPM distributions during spring conditions.
