Northwest Australian Shelf Ocean State Estimate: 2km Hourly MITgcm Simulation

Northwest Australian Shelf region oceanographic data from a global MITgcm simulation with 1/48-degree (2km) horizontal resolution. The dataset provides hourly estimates of three-dimensional variables like temperature, salinity, and velocity, plus two-dimensional fields including sea level anomaly and surface fluxes. It is produced by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Modeling ocean circulation and currents based on three-dimensional velocity data
• Analyzing upper-ocean heat budgets based on net heat flux and shortwave radiative flux variables
• Studying mixed layer dynamics based on ocean mixed layer thickness data
• Investigating tidal influences on shelf regions based on the synthetic surface pressure field for tidal forcing

Strengths

• High spatial resolution of 1/48-degree (approximately 2km at the equator)
• High temporal resolution with hourly output data
• Detailed vertical structure with 90 levels and ~1m resolution at the surface
• Includes both 3D (temperature, salinity, velocity) and 2D (fluxes, anomalies) variables

Limitations

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