Itämeren viikottaiset pintalämpötilat / Sea surface temperature weekly composites for the Baltic Sea

Satelliittikuvilta seurataan Itämeren pintalämpötilaa sulanveden aikaan. Pintalämpötila lasketaan NOAA-AVHRR (National Oceanic and Atmospheric Administration - Advanced Very High Resolution Radiometer) -instrumentin kuvilta. Lämpötila lasketaan yöaikaan otetuista kuvista kahden aallonpituuskanavan avulla käyttäen ns. Split Window -menetelmää. Kuvien erotuskyky on noin 1x1 km. Aineisto koostuu vuodesta 2007 lähtien koostetuista viikottaisista maksimiarvoista. Aineisto kuuluu SYKEn avoimiin aineistoihin (CC BY 4.0).

Satellite remote sensing is used to monitor the sea surface temperature in the Baltic Sea during the open water season from April to October. 
Sea surface temperature weekly product is calculated in the Finnish Environment Institute (SYKE) by using NOAA-AVHRR (National Oceanic and 
Atmospheric Administration - Advanced Very High Resolution Radiometer) night-time satellite images and Split Window method. The resolution for 
the satellite images used is 1 km x 1 km. The dataset covers weekly maximum data from year 2007 to current year.
