Satellite observations

Products based on satellite observations are produced in the Finnish Environment Institute (SYKE) in order to monitor environmental changes. These products include: surface temperature, algal blooms, water turbidity, CDOM, Secchi depth, chlorophyll-a concentration in the Baltic Sea and the snow-covered area in Finland and the Baltic Sea catchment.

Daily products and season composites are published in the TARKKA web map application. Products are available on the open SYKE web map services.

Finnish Environment Institute (SYKE) / Geoinformatics systems and Geoinformatics research units have produced these Remote Sensing products. Satellite products are based on several NASA, NOAA and EU Copernicus program satellite instruments. Currently Sentinel-2 (ESA), Sentinel-3 (ESA), Landsat-8 (NASA)and TERRA MODIS (NASA) satellites are utilized for monitoring. Previously also NOAA-AVHRR (NOAA), AQUA/TERRA MODIS (NASA), ENVISAT MERIS (ESA), RADARSAT (CSA) and AMSR-E (NASA) were utilized. ENVISAT MERIS and Sentinel-2 images have been downloaded from ESA. Landsat-8 and a subset of the AQUA MODIS images have been downloaded from NASA. NOAA-AVHRR and TERRA / AQUA MODIS images have been received by Finnish Meteorological Institute.

SYKE should be cited as a source if data is used in publications or in presentations or made available to the public in some other way. True-color images must be accompanied by an attribution text indicating the original data source. For example, for Sentinel-2 images: "Original images: ESA Copernicus Sentinel Data, SYKE" or Landsat-8 images: "Original images: USGS/NASA Landsat Program, SYKE". In case of scientific publications which explicitly make use of the products, the appropriate references are to be inquired from the Earth observation team: group@ymparisto.fi [group = eotuki.syke].
