Submesoscale Eddies in the South China Sea from MODIS SST, 2015-2024

Daily records from 2015 to 2024 of submesoscale eddies identified from MODIS Aqua and Terra sea surface temperature imagery. The dataset, created by Xi Chen, is distributed as daily TXT files containing eddy polarity, center coordinates, and diameter.

Use Cases

• Train deep learning models for eddy detection based on sea surface temperature imagery.
• Analyze the spatial distribution and frequency of submesoscale eddies based on center coordinates.
• Study eddy characteristics and dynamics based on recorded polarity and diameter.
• Validate ocean circulation models using observed eddy locations and properties.

Strengths

• Covers a 10-year time range from 2015 to 2024.
• Provides daily temporal resolution for eddy tracking.
• Data is openly available under a CC-BY-4.0 license.

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 South China Sea region.
