Abstract
Chlorophyll distribution in Lake Kinneret was estimated in a period of low chlorophyll-a concentrations (3–7 mg m−3) using remotely sensed data. The data set included high-spectral-resolution radiometric measurements in the range 400–750 nm, chlorophyll and suspended matter concentrations, Secchi disk transparency and vertical attenuation coefficients at 20 stations. The spectroradiometric data were used to create the algorithms suitable for quantitative determination of chlorophyll content. The present paper presents experimental field evidence showing that fluorescence can be successfully used for remote monitoring of chlorophyll-a content (with an estimation error −3) in productive inland waters with a background of variable and relatively high suspended matter concentration.
