COMBINED APPLICATION OF REMOTE-SENSING AND IN-SITU MEASUREMENTS IN MONITORING ENVIRONMENTAL PROCESSES

Combined use of remote sensing in the visible, infrared and microwave spectral regions, direct in situ measurements and model numerical expe riments makes it possible to study inland water bodies as elements of water body-catchment-atmosphere-systems with good spatial and temporal resolution. In this paper examples are presented of the remote sensin g methods developed for detection of hydrodynamics of large water bodi es (e.g. frontal and upwelling zones, internal waves, warm and cold su rface layers), monitoring of chlorophyll concentration, suspended mine rals and dissolved organic matter (DOM) in lakes, mapping of shallow w ater zones, wetlands and landscape structures, monitoring of ecologica l condition and changes of drainage basins, and studying the state of the atmosphere over lakes and catchment areas.
