Sea surface temperature, or lake surface temperature, is used to understand how the lake communicates with the Earth’s atmosphere. SST also provides fundamental information on our climate system and the link between broader earth system climate change. It is an essential parameter in predicting weather, modeling the atmosphere, and measuring shifts in our ecosystems. Passive observations are made with infrared (IR) sensors onboard multiple polar-orbiting and geostationary platforms, and microwave sensors onboard polar platforms.
Satellite SST is measured by NOAA’s Advanced Very High Resolution Radar (AVHRR), Visible Infrared Imaging Radiometer Suite onboard the Suomi National Polar-Orbiting Partnership spacecraft (VIIRS S-NPP), NOAA-20’s Visible Infrared Imaging Radiometer Suite sensor (VIIRS NOAA-20), and Meteorological Operational (MetOp) A, B and C satellites.
