December 5, 2024 marks the launch of the Sentinel-1C satellite, the latest addition to the Sentinel-1 constellation. This collection contains Level 2 Ocean (OCN) geophysical product metadata derived from Sentinel-1C's C-band synthetic aperture radar (SAR) imaging, processed by the Alaska Satellite Facility Distributed Active Archive Center. The metadata describes geolocated products for ocean wind, swell spectra, and surface radial velocity.
Use Cases
- Estimating ocean surface wind speed and direction based on the Ocean Wind field (OWI) component.
- Analyzing ocean swell patterns based on the Ocean Swell spectra (OSW) component.
- Mapping surface radial velocity for current studies based on the RVL component.
Strengths
- Data is derived from the Sentinel-1C satellite, launched December 5, 2024.
- Products can provide wind, wave, and current data with a spatial resolution down to 5 meters and coverage up to 400 kilometers.
- Metadata is ISO compliant XML created by the Alaska Satellite Facility DAAC.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- The availability of specific geophysical components depends on the acquisition mode.
Provenance
- Source
- Alaska Satellite Facility Distributed Active Archive Center (ASF DAAC)
- Collection Method
- Metadata created from Sentinel-1C SAFE format products.
