NASA Sentinel-3A Project: Land Surface Reflectance and Aerosol Parameters

The NASA Sentinel-3A Project provides Level 2 surface reflectance and aerosol parameters over land, generated by combining data from the OLCI and SLSTR instruments on the Sentinel-3 satellite. The dataset includes 29 measurement data files and 9 annotation data files, with surface reflectances provided on a 300-meter resolution grid. It is hosted on aws_open_data and is licensed under CC-BY-4.0.

Use Cases

• Monitoring land surface temperature (LST) changes based on the SLSTR instrument's high-accuracy measurements.
• Analyzing aerosol distribution and properties over land based on the provided aerosol parameters.
• Studying surface reflectance across 21 spectral bands for land cover classification.
• Validating climate and weather models using the combined OLCI and SLSTR synergetic product.

Strengths

• Data is sourced from two complementary satellite instruments (OLCI and SLSTR) providing synergetic products.
• SLSTR provides sea and land surface temperature measurements with a stated accuracy better than 0.3 Kelvin.
• OLCI measures reflected solar radiation in 21 spectral bands at a ground spatial resolution of around 300 meters.

Limitations

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