    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ocean colour validation; MERIS; in situ radiometry; water quality; CDOM; marin- och brackvattensekologi; Marine and Brackish Water Ecology;

    Sammanfattning : The thesis addresses validation activities associated with the use of in situ and satellite-based radiometers to assess water quality parameters, such as chlorophyll-a (Chl-a), total suspended matter (TSM) and coloured dissolved organic matter (CDOM- also known as yellow substances, YEL) in CDOM-dominated waters. In paper I, an inter-comparison of in situ radiometers is presented. LÄS MER

  3. 2. Baltic Sea from Space : The use of ocean colour data to improve our understanding of ecological drivers across the Baltic Sea basin – algorithm development, validation and ecological applications

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ocean Colour; MERIS; OLCI; water quality; marine ecology; coastal areas; Baltic Sea; Marine Ecology; marin ekologi;

    Sammanfattning : Coastal areas are the most densely populated areas in the world and thus are under immense anthropogenic pressure. To ensure their function and ecological role, coastal areas require continuous monitoring and management. The rapidly emerging field of satellite remote sensing provides a unique opportunity to monitor both land and oceans from Space. LÄS MER

  4. 3. Remote sensing in optically complex waters : water quality assessment using MERIS data
