Sentinel-3B: Combined Surface Reflectance and Land Surface Temperature Satellite Data

The dataset contains Level 2 surface reflectance and aerosol parameters over land, and Level 1B top-of-atmosphere reflectance, from the European Space Agency's Sentinel-3B satellite. Data is acquired by the Ocean and Land Colour Instrument (OLCI) and the Sea and Land Surface Temperature Radiometer (SLSTR), with a ground spatial resolution of around 300 meters and a 1270km swath. The data is provided in netCDF 4 format via the aws_open_data platform under a CC-BY-4.0 license.

Use Cases

• Monitoring land surface temperature (LST) for climatological and meteorological applications based on the SLSTR instrument's high-accuracy measurements.
• Analyzing surface reflectance across 21 spectral bands for land cover classification and change detection based on OLCI data.
• Estimating aerosol optical depth and other aerosol parameters over land based on the combined OLCI and SLSTR synergy product.
• Calibrating and validating atmospheric correction algorithms using the provided top-of-atmosphere radiance data.

Strengths

• Combines data from two complementary instruments (OLCI and SLSTR) for synergistic analysis.
• SLSTR provides land and sea surface temperature with a target accuracy better than 0.3 Kelvin.
• OLCI measures reflected solar radiation in 21 spectral bands with a consistent 300m spatial resolution.
• Data is structured into specific measurement and annotation files (e.g., 29 Measurement Data Files in the synergy product) following established netCDF formats.

Limitations

• Row count and total dataset size are unknown, which may limit suitability assessment for large-scale projects.
• Column-level documentation is absent; field semantics must be inferred from external user guides after download.
• Last update date is unknown; freshness unverified.
