Sentinel-1 SAR Ocean Swell Wave Spectra for Australasia, Near Real-Time

Sentinel-1 A, B, and C satellites have collected directional ocean swell wave measurements globally since 2014. This dataset provides homogenised swell wave number spectra, spectral partitions, and partition bulks for the Australasian region, including the Pacific islands, with data available from July 2015. The Australian Ocean Data Network presents these measurements in a consistent, near real-time format.

Use Cases

• Modeling ocean wave energy and swell propagation based on directional wave spectra.
• Assessing coastal erosion and flood risks based on near real-time wave measurements.
• Validating and calibrating numerical wave forecast models based on satellite-derived spectral partitions.
• Studying long-term changes in ocean swell patterns based on data collected since 2015.

Strengths

• Data collection spans from July 2015 to the present, providing a multi-year time series.
• Measurements are homogenised to a single, easily usable format from inconsistent source products.
• Coverage includes the Australasian region and the Pacific islands.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the Australasian regional focus.
