The Australian Earth System Simulator (ACCESS-NRI) is a large computer modelling system for research that includes atmospheric, ocean, sea-ice, and land surface models coupled to a range of chemical and biological models.

The ACCESS (Australian Community Climate Earth System Simulator) models currently support critical modelling and research that contributes to international global climate reports (IPCC), Bureau of Meteorology (BoM) seasonal forecasting, and climate adaptation policy among many other uses.

As a National Research Infrastructure, ACCESS-NRI will provide a merit-based, open access platform for Australian researchers to implement the ACCESS models in climate, weather and Earth Systems research across all time scales, from paleo-climate simulations to daily and seasonal weather forecasting, to multi-decadal future climate simulations.

ACCESS-NRI brings together the weather and climate observations, research and modelling capabilities of the Bureau of Meteorology (BoM), CSIRO and the Australian university sector, in collaboration with key international partners.

ACCESS-NRI is supported by the Australian Government’s National Collaborative Research Infrastructure Strategy (NCRIS).
