"Accurate assessment of concentration of chlorophyll a (Chla) and correct identification of algal blooms by remote sensing have previously been a great challenge in the optically complex Case-2 Waters. In this paper, we used a large biooptical data set to model the remote-sensing reflectance in an extremely turbid and biologically productive Lake Taihu in China," investigators in Nanjing, People's Republic of China report.
"The conceptual three-band model [R-rs(-1) (lambda(1)) - R-rs(-1)(lambda(2))] X R-rs (lambda(3)) (where R-rs represents remote-sensing reflectance just above the water surface) to retrieve Chla concentration was calibrated and validated, and a ...
