Great Barrier Reef Hydrodynamic Model Results at 1km Resolution

GBR1_H2p0 hydrodynamic model results for the Great Barrier Reef shelf at 1km resolution. The model ran in near-real-time with daily updates until January 2024, when river-flow data access was lost. It is nested within a 4km-resolution model and uses atmospheric and river flow data for forcing.

Use Cases

• Analyze near-real-time hydrodynamic patterns using the 1km-resolution model outputs for the Great Barrier Reef shelf.
• Study model nesting dynamics between the 1km-resolution GBR1 and 4km-resolution GBR4 hydrodynamic models.
• Investigate the impact of atmospheric data from the ACCESS-R model and river flow data on shelf-scale ocean boundaries.

Strengths

• High-resolution 1km-scale hydrodynamic modeling for the Great Barrier Reef shelf.
• Model incorporates multiple data sources: atmospheric data, measured river flow, and nested ocean boundary data.
• Near-real-time daily operational updates were maintained until January 2024.

Limitations

• Data updates ceased in January 2024 due to lost access to critical river-flow forcing data.
• Specific data variables, row counts, and column structures are not provided in the input.
• Primary data formats (HTML, WMS) are not typical for direct numerical analysis and may require specialized tools.
