Great Barrier Reef Biogeochemical Model Data at 4km Resolution

4km-resolution biogeochemical model version 3.0 simulates water quality for the Great Barrier Reef. The dataset, now superseded, was produced by the Australian Ocean Data Network and used a 'catchment real time' configuration with a six-month lag for source catchment inputs. It was archived by custodians in April 2024.

Use Cases

• Analyze temporal trends in modeled chlorophyll-a concentrations across the 4km grid.
• Validate hydrodynamic model outputs against biogeochemical parameters like nutrient loads.
• Assess the impact of different catchment forcing methods (P2R, Empirical, Furnas) on reef water quality predictions.

Strengths

• High spatial resolution of 4km for detailed regional analysis.
• Model incorporates three distinct catchment forcing methodologies over its operational period.

Limitations

• Dataset is superseded and archived, indicating it is not the current operational version.
• Specific row counts, column details, and data volume are unknown.
• Access requires arrangement with custodians, indicating potential availability barriers.
