Sentinel-2 ACOLITE-DSF Aquatic Reflectance for the Conterminous United States

Sentinel-2 ACOLITE-DSF Aquatic Reflectance for the Conterminous United States is a dataset of unitless water-leaving radiance reflectance values. The data was produced by the United States Geological Survey using the ACOLITE software's dark spectrum fitting algorithm for atmospheric correction. The dataset covers the conterminous United States.

Use Cases

• Monitor water quality changes in inland and coastal waters based on aquatic reflectance.
• Develop or validate remote sensing algorithms for atmospheric correction over water bodies.
• Model aquatic ecosystems and phytoplankton dynamics based on water-leaving radiance data.
• Assess sediment load and turbidity in lakes and rivers based on spectral reflectance.

Strengths

• Data is processed with a specific, documented atmospheric correction algorithm (ACOLITE DSF, version 20221114.0).
• Spatial coverage is explicitly defined as the conterminous United States.
• Produced by the authoritative United States Geological Survey.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count, file formats, and last update date are unknown, which may limit suitability assessment.
