Copernicus Sentinel-3A dataflow gathers momentum

Following the release of the first operational data from the Sentinel-3 satellite’s Ocean and Land Colour Instrument in October, data from the Sea and Land Surface Temperature Radiometer are now available.

Thursday, 17 November 2016


The instrument measures the intensity of radiant energy emitted from land and sea surfaces in nine spectral bands including visible and infrared channels.

Measuring sea surface temperature is important as the ocean plays an important role in shaping our climate and weather patterns.

Warm ocean waters provide the energy to fuel storm systems that provide much needed fresh water on land; at the same time, they can heighten the destructive powers of storms.

Anne O’Carroll, Surface Temperature Radiometry Team Leader at EUMETSAT said: “The release of Sentinel-3A SLSTR Level-1b data to the wider marine user community is an exciting milestone and important step forward to the provision of high quality, dual-view, sea surface temperature products from this innovative new instrument.

“First indications are that this instrument is living up to the expectations to provide very accurate surface temperature observations with the view to distribute, in near-real time, climate quality, operational products.

“These are an essential reference source of measurements, contributing to the global constellation of satellite sea surface temperature data.”

About Sentinel-3A

Carrying a suite of instruments, Sentinel-3A has been designed to measure Earth’s oceans, land, ice and atmosphere to monitor large-scale global dynamics and to provide critical near-real time information for numerous ocean, land and weather applications.

While the operations of the Sentinel-3A satellite are carried out by EUMETSAT, the mission is managed jointly by ESA and EUMETSAT.

ESA is responsible for the land data products and EUMETSAT for the marine products – all of which are made available for application through Copernicus services.
