   Sammanfattning : Rock bands are foundational for modern day music life. These small groups provide well-being and self-fulfillment to its members, as well as fuel for the cultural life and the increasingly highlighted creative industries. Rock bands, however, are particularly difficult to organize. LÄS MER

4. 3. Uncertainty measurements and validation of ocean colour data in optically complex waters

   Författare :José M. Beltrán-Abaunza; Susanne Kratzer; Samantha Lavender; Paul Glantz; Sven Blomqvist; Stockholms universitet; []
   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
