Access to raw model output
The eReefs GBR4 and GBR1 model results are published as National Reference Datasets via the NCI.
Model results are published as one dataset per unique EMS model configuration, and dataset names follow our Model simulations naming protocol which embeds some semantic information about that configuration in the dataset ID. The raw results files are published as a large number of files that comply with the NetCDF Climate and Forecast (CF) Metadata Conventions. All the datasets are licensed as Creative Commons by Attribution (CC-BY 4.0), and may be freely referenced by other data products. Please refer to the metadata record for each dataset for the preferred citation.
Accessing eReefs model results via HTTPS
We recommend that researchers access these datasets via the NCI’s THREDDS Server, which supports a number of standard HTTP data-query protocols, including OPenDAP, WMS, and NetCDF Subset. It is also possible to download the individual results files from this service, but we do not recommend that approach, as some of these datasets are very large (10s of TB). It is much more efficient to query just the subset of data you need!
You can browse the available eReefs datasets in the NCI THREDDS catalog at:
This is also linked off of their top level (easy to remember URL):
For each dataset, the THREDDS catalog exposes both the individual NetCDF files and a time-based aggregation that allows the entire dataset to be queried from a single URL. See the tables below for links.
Accessing eReefs model results on NCI Gadi HPC or NCI Nirin Cloud
Researchers with existing high-performance compute allocations on the NCI may apply for access to the fx3 project if you wish to use the eReefs model results dataset files in your HPC workflows on Gadi or from NCI Nirin Cloud servers. Please refer to the NCI User Guides for detailed instructions.
GBR4 Regional Model Results
GBR4 Near-Real-Time Model Results
The following datasets are being continually added to as outputs of the GBR4 regional model running in near-real-time mode.
The time lag between ‘now’ and the most recent timestamp available in the dataset varies depending on how long it takes us to acquire and ingest the third-party forcing data, but is usually about one week.
These datasets can all be visualised and queried via the CSIRO eReefs Data Explorer

GBR4 BGC Scenario Hindcast Model Results
The following sets of GBR4 model results are from hindcast scenario runs based on the best available catchment forcing data combined with nutrient loads based on a variety of possible management scenarios.
These datasets can all be visualised and queried via the CSIRO eReefs Data Explorer

Deprecated GBR4 Model Results
The following sets of GBR4 regional model results are older, and have been superseded by the more recent results listed above.
We recommend that you do not use these for new research projects.
They remain online and available for reference purposes for now, but we plan to remove them from the NCI THREDDS server in April 2024 to free up storage space for new datasets to be published. They are not available for visualisation in the eReefs Data Explorer.
GBR1 Shelf Model Results
Near-Real-Time GBR1 Model Results
The following datasets are being continually added to as outputs of the GBR1 shelf model running in near-real-time mode.
The GBR1 near-real-time models should lag their GBR4 equivalents by only a few hours.
These datasets can all be visualised and queried via the CSIRO eReefs Data Explorer

Deprecated GBR1 Model Results
The following sets of GBR1 shelf model results are older and have been superseeded by newer data products.
We recommend that you do not use these for new research projects.
They remain online and available for reference purposes for now, but we plan to remove them from the NCI THREDDS server in April 2024 to free up storage space for new datasets to be published. They are not available for visualisation in the eReefs Data Explorer.
