Note: The GBR1 and GBR4 models (including hydro, river tracer and BGC) are no longer updated in near-real-time. New model outputs may be added in the future.
This page shows the daily minimum, maximum and temperature range on the Great Barrier Reef based on the 4km eReefs Hydrodynamic model. This is an experimental product that is intended to help investigate whether daily temperature range is a useful indicator of resistance to coral bleaching.
Source data
The videos/images on this page are based on the 4km eReefs Hydrodynamic model (v4.0) of the Great Barrier Reef. The raw data is available from the NCI THREDDS server (hourly) and the aggregate data from the AIMS eReefs THREDDS server (daily, monthly, yearly and overall). These map layers are also available for inspection in the eReefs Data Explorer.
Data coverage
The data on this page may not reflect the most current conditions, as the GBR1 and GBR4 model runs are no longer updated on a regular basis.
To browse the latest available model data, refer to the NCI THREDDS server.
