SUSPENDED MATTER DYNAMICS IN LAKE CONSTANCE IN 2003DERIVED FROM MERIS AND MODIS SATELLITE DATA

摘要

Lake Constance is the third largest lake in CentralEurope. The river Rhine, which passes the lake, importsa significant amount of mineralic particles. Theirtransport and sedimentation within the lake is of importancefor a number of applications, for example shiptraffic, pumping stations for extraction of drinkingwater, hydraulic engineering, fishery, and ecology.Only satellites offer a cost-effective way for obtainingtime series of the spatial distribution of suspendedmatter in such a large lake. The potential of satellitebasedmonitoring of suspended matter is investigatedusing MERIS and MODIS time series from 2003, addressingtwo specific questions: (1) Are these sensorssuited to derive useful time series of medium- andlarge-scale patterns of suspended matter in Lake Constance?(2) Are the quantitative results from the twosensors comparable?
