Retrieval of Limnological Parameters of Perialpine Lakes by Means of Meris Data

چکیده
The capabilities of the Envisat MEdium Resolution Imaging Spectrometer (MERIS) for monitoring water quality parameters of oligoto mesotrophic lakes in Austria and of Lake Garda in Italy are investigated within the project AO-164, “Environmental Research in the Eastern Alps”. From May to September 2003 field measurements and routine measurements from limnological stations are available parallel to MERIS acquisitions. The surface reflectance was derived from Level 1b MERIS data by means of radiative transfer calculations. An empirical algorithm was developed for mapping the concentration of chlorophyll a (Chl-a) based on the ratio between reflectance in MERIS bands 7 (665 nm) and 5 (560 nm).
