Description
Sentinel-3B satellite data provides global and regional top-of-atmosphere radiances and brightness temperatures from the Sea and Land Surface Temperature Radiometer (SLSTR). This Level 1B product contains full-resolution, geolocated measurements from visible, NIR, SWIR, and thermal infrared channels, along with quality flags, pixel classifications, and meteorological annotations. Its principal objective is to deliver sea and land surface temperatures with an accuracy better than 0.3 Kelvin for climatological and meteorological applications.
Use Cases
Monitoring global sea surface temperature (SST) trends based on thermal infrared channel brightness temperatures.
Analyzing regional land surface temperature (LST) for urban heat island studies using the dual-scan nadir and along-track views.
Detecting active fires and thermal anomalies utilizing the instrument's two dedicated fire detection channels.
Assessing atmospheric conditions and data quality for downstream processing using the included meteorological annotations and pixel classification flags.
Strengths
Designed for high accuracy, with a stated objective of providing surface temperatures to better than 0.3 Kelvin.
Includes advanced features over predecessor instruments, such as a wider swath, higher resolution in some channels, and dedicated fire detection bands.
Contains extensive ancillary data, with 54 to 76 annotation files providing quality flags and meteorological context for the 22 to 34 measurement files.
Limitations
Metadata completeness is low; column names, row counts, and file sizes are not provided on any platform.
The product structure is variable, containing either 77 or 111 total files depending on non-operational configuration components.
A key platform (nasa_earthdata) shows conflicting metadata, with one entry listing tags, license, and an update date, and another identical entry listing none.
