Sea Surface Temperature Services

The dual view, nine-channel Sea and Land Surface Temperature Radiometer (SLSTR) measures sea surface temperature, sea surface temperature, land surface temperature, sea-ice and land ice temperature, atmospheric aerosols, cloud properties and fire radiative power.

SLSTR continues the sea surface temperature record collected by the (A)ATSR instruments on ERS and Envisat satellites.

The aim is to collect highly accurate measurements to provide a reference dataset for other sea surface temperature missions on other satellites.

Sea surface temperature data is used as input for weather and ocean forecasting, to observe and monitor ocean current systems and ocean fronts, eddies, upwelling areas, marine ecosystems and the development of large scale El Niño/La Niña events.

Because of the importance of sea surface temperature to the global heat budget it is monitored as an essential climate variable (ECV).

These data are also used to improve understanding of the ocean surface layer, upper ocean variability, energy transfer, air-sea interactions and the impact of changes in the temperature of the ocean surface over the course of the day and changes between the temperature at the ocean surface and the depths below.

SST data is also used to help manage marine ecosystems, e.g. identifying frontal areas with large shoals of fish or monitoring coral bleaching events, and for travel and tourism.

SLSTR products

The products are available in:

  • Near-Real-Time (NRT): products shall be available to the users within three hours after sensing.
  • Non-Time-Critical (NTC): products available to the users within one month after sensing.

How to get SLSTR data

Users need to be registered to get access to the SLSTR products. To do this you need to use our Earth Observation Portal (EOP). To access the Earth Observation Portal (EOP) for the first time, users need to create an account. Once the account has been created, you can log in to view and modify your profile, service subscriptions and licence arrangements.

SLSTR products are available:

All Sentinel data products are distributed using a Sentinel-specific variation of the Standard Archive Format for Europe (SAFE) format specification. The information is contained in a single package, with objects encoded in NetCDF format.

Full details can be found on the Sentinel Formats page.

How to use SLSTR data

The Sentinel-3 Toolbox consists of a rich set of visualisation, analysis and processing tools for the exploitation of SLSTR data.

Watch this video demonstration from our expert Anne O'Carroll.

It will be possible to see imagery from SLSTR on our imagery visualisation tool, EUMETView.

The Sentinel-3 SLSTR User Guide on the ESA website provides a high level description of the available instrument modes and products.
