CFOSAT SWIM Tracking: Southern Ocean Swell Propagation and Dissipation

462.9 KB of MATLAB programs and data supporting an analysis of Southern Ocean swell propagation and dissipation. The dataset includes 25 groups of tracked swell trajectories, buoy observations, and satellite data points. It was authored by Wei Dai and last updated in April 2026.

Use Cases

• Analyze swell propagation and dissipation rates based on tracked swell trajectories.
• Validate satellite-derived wave data against buoy observations based on the included buoy data.
• Reproduce error analysis for swell tracking methods based on the provided MATLAB program Fig_10.
• Study storm source influences on swell characteristics based on the storm source information.

Strengths

• Includes 25 distinct groups of tracked swell trajectories.
• Combines satellite (CFOSAT SWIM) data with buoy (NDBC) observations for validation.
• Provides MATLAB programs for analysis and plotting, facilitating reproducibility.

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 Southern Ocean focus.
