MONITORING OF SURFACE NATURAL WATERS USING REMOTE SENSING FROM AIRBORNE PLATFORM

摘要

The inverse process, I. e. to infer the content of the natural waters from measurements of upwelling daylight at selected wavelengths is discussed in view of remote sensing applications. Some results of thematic mapping of oligotrophic natural waters are discussed using multispectral satellite ( MSS ) images and suspended sediments concentrations on separate routes of a scientific vessel. A radiation transfer model has been used to represent remote sensing radiance's of selected MSS imagery in terms of concentrations obtained from probes of suspended sediments in the Baikal Lake waters on the routes, which were carried out in the mouth of the river Selenga, a tributary of the Lake. Solving the inverse problem of the atmosphere/hydrosphere optics based on angular and spectral characteristics, suspended sediments concentrations and the contents of their dispersed matter have been retrieved. The microstructure of suspended particles is also studied that is in a good agreement with that given by regression techniques between data of remote sensing and monitoring of sediments from the vessel.
