Abstract
The remote sensing of chlorophyll-a concentration of inland water is troublesome because of the numerous pollutant substances. It was found that the reflectance ratio R(700 nm)/R(675 nm) depends on not only chlorophyll-a concentration but also the scattering and absorption coefficients of suspensions and dissolved organic matter. The absorption of phycocyanin at 624 nm is a very important spectral feature for estimation of chlorophyll-a concentration as well as that of chlorophyll-a. New algorithms were developed, in which reflectance ratio R(600 nm)/R(624 nm) or R(560 nm)/R(624 nm) was used as water quality correction.
