Great Barrier Reef 4km Hydrodynamic Model Results v4.0

GBR4_H4p0_ABARRAr2_OBRAN2020_FG2Gv3_Dhnd model provides 4km-resolution regional-scale hydrodynamic data for the Great Barrier Reef. The simulation is a complete hindcast, forced with atmospheric, ocean boundary, tidal, and river data from 64 catchments.

Use Cases

• Analyze hydrodynamic patterns using the 4km-resolution regional-scale model output for the Great Barrier Reef.
• Study river discharge impacts on reef systems using data from 64 river boundaries with measured stream flow and temperature.
• Validate coastal ocean models by comparing outputs against this hindcast simulation forced with BARRA atmospheric and BRAN2020 ocean boundary data.
• Investigate tidal influences on reef hydrodynamics using inputs from the global TPXO tide model.

Strengths

• Model output is at a 4km spatial resolution for regional-scale analysis.
• Forcing data integrates inputs from 64 distinct river catchments.
• Simulation is a complete hindcast run, providing a full historical time series.

Limitations

• Data is presented in HTML and PNG formats, limiting direct programmatic analysis of raw model outputs.
• Specific temporal coverage, row count, and column structure of the underlying data are not provided.
