Great Barrier Reef Hydrodynamic Model Results at 4km Resolution

Comprising results from version 4.0 of the 4km-resolution regional-scale hydrodynamic model of the Great Barrier Reef (GBR4). The model is forced with atmospheric data from BARRA, ocean boundaries from BRAN2020, the global TPXO tide model, and river data from 64 catchments. It is a complete hindcast model run that succeeds the GBR4_H2p0 model.

Use Cases

• Analyze hydrodynamic patterns using the 4km-resolution model grid for the Great Barrier Reef region.
• Study the influence of river inputs from 64 modeled catchments on coastal oceanography.
• Validate or compare other ocean models against this hindcast simulation forced with BARRA atmospheric reanalysis and BRAN2020 ocean boundaries.
• Investigate tidal dynamics in the Great Barrier Reef using the integrated global TPXO tide model.

Strengths

• Model results are based on a high 4km spatial resolution grid for the Great Barrier Reef.
• The simulation integrates multiple high-quality forcing datasets, including data from 64 river catchments.
• The dataset represents a complete hindcast run, providing a consistent temporal record.

Limitations

• The dataset consists of model outputs, not direct observations, and is subject to model assumptions and errors.
• Specific data formats (PNG, HTML) may limit direct quantitative analysis without access to underlying raw model files.
• The temporal coverage and update frequency of the model run are not specified in the input.
