eReefs GBR4 DA Hydrodynamic Model: Temperature Reanalysis

Decommissioned in May 2022, this dataset contains hydrodynamic model data for the Great Barrier Reef at 4 km resolution. The Ensemble Optimal Interpolation system assimilates temperature data from moorings, gliders, and satellite SST within a 6-hour window. The Australian Ocean Data Network produced this first version of a reanalysis for the GBR4 grid.

Use Cases

• Modeling ocean temperature variability based on assimilated mooring and glider data.
• Analyzing seasonal forecast error patterns based on the reported 0.4 to 0.7 degree C range.
• Studying hydrodynamic processes in the Great Barrier Reef based on the 4 km resolution model grid.
• Validating other ocean models against this reanalysis product.

Strengths

• Assimilates multiple data sources including moorings, gliders, and satellite SST.
• Provides a reanalysis product at 4 km resolution for the Great Barrier Reef.
• Reports mean forecast error ranges from 0.4 to 0.7 degrees C.

Limitations

• Dataset was decommissioned and is no longer available via the original server.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
