Water turbidity weekly composite for the Baltic Sea 2003-2011

Satellite remote sensing is used to monitor turbidity of surface water in the Baltic Sea during the open water season from April to October. Turbidity represents the clarity of the water. Turbidity is caused by phytoplankton, minerals or dead organic matter in water. A turbidity weekly composite calculated in the Finnish Environment Institute (SYKE) is a pixel-wise weekly average of images of the past week or - if no more good images are available - the best image of the past week. Envisat MERIS (Medium Resolution Imaging Spectrometer) 3rd Reprocessing data has been processed to turbidity values using C2R (Case 2 Regional) algorithm. The dataset covers years 2003-2011. The spatial resolution is 300 meters.

    Suomen ympäristökeskuksessa (SYKE) seurataan satelliittikuvilta Itämeren sameutta sulan veden aikaan. Veden sameus koostuu vedessä olevista pienistä hiukkasista (kasviplankton, mineraalit tai kuollut orgaaninen aines). Sameuden määrä on laskettu Envisat MERIS (Medium Resolution Imaging Spectrometer) -instrumentin 3rd Reprocessing -datasta käyttäen C2R (Case 2 Regional) -vedenlaatuprosessoria. Sameuden viikkokomposiitti sisältää pikselikohtaisen keskiarvon kyseisen viikon havannoista tai viikon ainoan kuvan. Aineisto koostuu vuosien 2003-2011 viikkokomposiiteista. Kuvien maastoerotuskyky on 300 metriä. Aineisto kuuluu SYKEn avoimiin aineistoihin (CC BY 4.0).
