SLSTR is the Sea and Land Surface Temperature Radiometer (SLSTR) aboard the European Space Agency’s (ESA’s) Sentinel-3 satellite series. The SLSTR is a conical scanning imaging radiometer with dual view capability. The sensor has a swath width of 1420km and measures the Earth's radiation in 9 bands covering the visible, shortwave infrared, and thermal infrared areas of the spectrum.
SLSTR Level-1B and Level-2 products are available to the public. The product described here is the Level-1B Brightness Temperatures and TOA Radiances that are ortho-geolocated and resampled. Level-2 products include Sea Surface Temperature, Land Surface Temperature, and Fire radiative power. The Level-1B data are delivered in two resolutions, 500m for the reflective bands, and 1 km for the thermal infrared bands.
The SLSTR, aboard Sentinel-3A and -3B, together will provide a daily revisit time. A single satellite provides for global coverage at the equator every two days.
For details of Level-1B processing, see the technical guide on L1B processing.

- MMM = the mission ID: S3A = SENTINEL-3A, S3B = SENTINEL-3B, S3_ = Both A and B
- SL = the source (SL = SLSTR)
- L = the processing level
- TTTTTT = the data Type ID (L1 SLSTR radiance and BT: RBT___)
- yyyymmddThhmmss is the sensing start time
- YYYYMMDDTHHMMSS is the sensing stop time
- YYYYMMDDTHHMMSS is the product creation date
- [instance ID] The field consists of 17 characters, either uppercase letters or digits or underscores "_".
- GGG identifies the processing center that generated the file
- [class ID] identifies the class ID for instrument data products with conventional sequence P_XX_NNN, where P is the platform, XX is the timeliness of the workflow, and NNN is the baseline collection
