Abstract

Based on in situ water sampling and field spectral measurement from June to September 2004 in Lake Chagan, this paper partly addressed to develop a new approach named inverse continuum removal to isolate fluorescence peak for the comparison of water reflectance spectra with different Chl-a concentration during the summer. Next, an attempt was made to link the reflectance changes including band depth and band area with Chl-a concentration and evaluate the potential of remote sensing data for inversion. Results show that the Chl-a determined from band depth and band area of fluorescence peak with the determination coefficient (R2) higher than 0.74. The study also proves that inverse continuum removal analysis can be used to effectively determine the Chl-a concentration of Lake Chagan in Northeast China.
