Sentinel-1B Ocean Product: Wind, Wave, and Current Data

Sentinel-1B Level 2 Ocean products provide geolocated geophysical data derived from C-band synthetic aperture radar imaging. The dataset includes components for ocean wind fields, swell spectra, and surface radial velocity, with resolutions down to 5 meters and coverage up to 400 kilometers. The mission ended in August 2022, and the data is mirrored from the Copernicus Data Space Ecosystem.

Use Cases

• Estimating surface wind speed and direction at 10m height based on the Ocean Wind field (OWI) component.
• Analyzing ocean swell wave patterns based on the Ocean Swell spectra (OSW) component.
• Measuring surface current velocities based on the Surface Radial Velocity (RVL) component.
• Monitoring oceanographic conditions using dual-polarization radar data from Sentinel-1B.

Strengths

• Provides data from four imaging modes with resolutions down to 5 meters.
• Offers dual polarization capability and short revisit times.
• Covers up to 400 kilometers per imaging swath.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Last updated 2021-12-24 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
