S-MODE: Sub-Mesoscale Ocean Model Output

Regional Ocean Modeling System (ROMS) output files for the Sub-Mesoscale Ocean Dynamics Experiment (S-MODE) are provided in large NetCDF format. The model aims to quantify how short-scale ocean dynamics influence vertical exchanges of physical and biological variables. Output is limited to the S-MODE field campaign region and uses hourly ERA5 atmospheric forcing data.

Use Cases

• Analyzing sub-mesoscale ocean dynamics and their role in vertical transport based on the model's high-resolution physics.
• Studying the influence of hourly atmospheric forcing (ERA5) on ocean surface conditions and mixing.
• Validating and comparing field campaign observations with regional ocean model simulations for the S-MODE region.
• Investigating the three-dimensional distribution of ocean temperature and salinity variables likely contained in the model output.

Strengths

• Data originates from a NASA-led scientific field campaign and modeling effort (S-MODE).
• Model output uses high-temporal-resolution (1hr) ERA5 atmospheric forcing data.
• Cross-platform presence on Data.gov and NASA EarthData signals its importance and official provenance.

Limitations

• Metadata completeness is low: specific column names, row counts, and file sizes are not provided.
• Conflicting 'last updated' dates across platforms (2013, 2026) create uncertainty about data freshness.
• Files are described as 'very large,' requiring cloud-based analysis and posing an access barrier.
