Water quality monitoring by Thematic Mapper in coastal environments : A performance analysis of in-water algorithms and atmospheric correction proceduresFunded under: JRC-REMSENS 4C
The Thematic Mapper's ability to monitor localised phenomena associated with anthropogenic pollution in coastal waters has been investigated with reference to experimental data collected on a test site in the Gulf of Naples. In-situ measurements yielded the algorithms for chlorophyll and sediment retrieval as well as an optical model for the computation of the subsurface reflectance as a function of water composition, specific to the site. The algorithm's performance was assessed through a sensitivity analysis. Sensitivity analysis techniques were similarly used to evaluate the performance in the coastal environment of three atmospheric correction models. A comparison with sea-truth data shows a satisfactory correspondence between measured concentrations and concentrations retrieved from the TM data by the atmospheric correction procedures and in-water algorithms.
