Description
Sentinel-3A's Sea and Land Surface Temperature Radiometer (SLSTR) provides Level-1B full-resolution, geolocated top-of-atmosphere radiances and brightness temperatures across visible, NIR, SWIR, and thermal infrared channels. The dataset includes co-located nadir and along-track views, quality flags, pixel classification, and meteorological annotations. It is designed to deliver global sea and land surface temperature data with an accuracy target better than 0.3 Kelvin.
Use Cases
Monitoring sea surface temperature (SST) for climatological studies based on thermal IR channel data.
Analyzing land surface temperature (LST) for regional environmental assessments using dual-scan radiometer measurements.
Detecting active fires using the instrument's dedicated fire detection channels.
Deriving aerosol optical depth over land from synergistic OLCI+SLSTR Level-2 products referenced in related entries.
Assessing surface reflectance for land cover classification from visible and NIR radiance data.
Strengths
Instrument designed for high accuracy, with a target of better than 0.3 K for surface temperature measurements.
Product includes extensive annotation data, with 54 to 76 files dedicated to quality flags, pixel classification, and meteorological data.
Data is cross-platform, appearing on both Data.gov and NASA EarthData, indicating established use and validation.
