Sentinel-3 is primarily an ocean mission, however, the mission will also be able to provide atmospheric and land applications. The mission will provide data continuity for the ERS, Envisat and SPOT satellites.
Sentinel-3 will make use of multiple sensing instruments to accomplish its objectives; SLSTR (Sea and Land Surface Temperature Radiometer), OLCI (Ocean and Land Colour Instrument), SRAL (SAR Altimeter), DORIS, and MWR (Microwave Radiometer).
The Sentinel-3A Sea and Land Surface Temperature Radiometer (SLSTR) Level-1B data is now available in near real-time timelines. The release of SLSTR L1B data follows the release of the first operational data from the Ocean and Land Colour Instrument in October.
SLSTR nadir view geolocation accuracy meets the mission requirements (0.5 pixel as per S3 MRTD, 2011), following update of the SLSTR instrument pointing based on commissioning phase results. The geo-location accuracy of oblique view is not fully nominal.
SLSTR TIR radiometric accuracy meets the mission requirements (S3 MRTD, 2011).
The SLSTR NRT Level-1B products can be accessed via the following means:
- The EUMETSAT Data Centre, accessible via our Earth Observation Portal (EOP)
- Our new pilot Copernicus Online Data Access (CODA) service. It is an online rolling archive with http access.
Other products from Sentinel-3 will be made available in the coming weeks.
More information on SLSTR products and accessing the data can be found on our Sea Surface Temperature webpage.
