Algorithm To Derive Inherent Optical Properties From Remote Sensing Reflectance In Turbid And Eutrophic Lakes, Kun Xue, Emmanuel Boss, Ronghua Ma, Ming Shen

Marine Sciences Faculty Scholarship

Inherent optical properties play an important role in understanding the biogeochemical processes of lakes by providing proxies for a variety of biogeochemical quantities, including phytoplankton pigments. However, to date, it has been difficult to accurately derive the absorption coefficient of phytoplankton [aph(λ)] in turbid and eutrophic waters from remote sensing. A large dataset of remote sensing of reflectance [ Rrs (λ)] and absorption coefficients was measured for samples collected from lakes in the middle and lower reaches of the Yangtze River and Huai River basin (MLYHR), China. In the process of scattering correction of spectrophotometric measurements, the particulate absorption coefficients …
