Sentinel-1 SAR Ocean Swell Wave Spectra for Australasia and Pacific Islands

Australasian region and Pacific islands are covered by directional ocean swell wave data from the Sentinel-1 A, B, and C satellites. The dataset contains wave number spectra, spectral partitions, and partition bulks, homogenized from inconsistent source products into a single format. Data collection began in 2014, with data delivered from July 2015, and is presented in delayed mode by the Australian Ocean Data Network.

Use Cases

• Modeling ocean wave energy and climate impacts based on directional swell wave spectra.
• Validating numerical wave forecast models using satellite-derived wave number spectra.
• Studying long-term swell patterns in the Australasian region based on data collected since 2014.
• Analyzing spatial distribution of wave partitions across the Pacific islands.

Strengths

• Data is homogenized to a single, easily usable format, removing inconsistencies in wave number bins, values, and variables.
• Provides global directional wave measurements from the identical C-band SAR instruments on three Sentinel-1 satellites.
• Covers the Australasian region including the Pacific islands, with a temporal scope starting from July 2015.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is presented in delayed mode, which may not be suitable for real-time applications.
