Abstract
In freshwater bodies, the presence of considerable amounts of optically active components with a high changeability of qualities makes the interpretation of remote sensing measurements difficult, when these are based only on the upward radiation brightness characteristics. A higher information content and reliability of measurements in such cases may be ensured by means of a combined use of both the brightness and degree of polarization of the upwelling radiation. An experimental test of this approach was made in Lake Onega. The effective wavelength, obtained from the spectral distribution of the brightness coefficient, was considered a brightness characteristic. Water quality indices were determined with the help of multiple regression equations. The obtained correlation coefficient for relative water transparency is R=0.78 ± 0.06 and the regression level average quadratic error is S z = ± 0.32 m.
