GBR1_H2p0_B3p2_Cfur_Dnrt: Retired Great Barrier Reef Biogeochemistry Model Results

Version 3.2 of the 1km-resolution regional-scale biogeochemistry and sediments model for the Great Barrier Reef, forced by a 1km hydrodynamic model. The dataset was retired by its authors in February 2026 due to an error causing unrealistic Chlorophyll-a levels. The model ran in near-real-time mode, updating daily, until January 2024 when sensor damage halted river-flow data input.

Use Cases

• Analyze historical biogeochemical model performance based on the 1km-resolution regional-scale simulation mentioned in the description.
• Study the impact of erroneous river-flow forcing on sediment predictions based on the described catchment input relationships.
• Compare retired model outputs with newer datasets based on the stated inconsistency with the GBR4_H4p0_ABARRAr2_OBRAN2020_FG2Gv3_B4p2_Cq5b_Dhnd dataset.

Strengths

• Model outputs are at a 1km spatial resolution for the Great Barrier Reef region.
• The simulation used a named configuration (GBR1_H2p0_B3p2_Cfur_Dnrt) with specified forcing and catchment inputs.

Limitations

• The dataset was retired in February 2026 due to a scientific error producing abnormally high Chlorophyll-a levels.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data freshness is limited; the model stopped updating in January 2024.
