Gotland Basin Ocean State Estimate: Hourly 2km MITgcm Simulation

A regional multivariate oceanographic state estimate from a global MITgcm simulation with a focus on the Gotland Basin. The dataset provides hourly three-dimensional variables like temperature, salinity, and velocity, plus two-dimensional fields such as sea level anomaly and heat flux. It is produced by NASA and was last updated in March 2026.

Use Cases

• Modeling ocean circulation patterns based on three-dimensional velocity fields
• Analyzing upper-ocean heat budgets based on net heat flux and shortwave radiative flux variables
• Studying salinity and freshwater dynamics based on salinity and net freshwater flux data
• Investigating tidal influences on sea level based on the synthetic surface pressure field for tidal forcing

Strengths

• High-resolution simulation with 1/48-degree (approximately 2km) nominal horizontal grid
• Optimized vertical resolution with 90 levels and about 1-meter resolution at the surface
• Hourly temporal output for capturing short-term oceanographic processes

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
