Regional Atmosphere Model (ACCESS-rAM)
ACCESS-rAM3 is a fully supported regional model, created to understand and project weather with a unique Australian focus. This model includes atmosphere and land components, and it is an implementation of the UK Met Office (UKMO) regional nesting suite.
ACCESS-rAM3 allows Australian researchers to choose the time and location they wish to simulate. It also enables users to seamlessly use land-surface initial conditions from other available sources rather than relying on operational data, which are not readily available to the public.
This model enables the vital research undertaken by the ARC Centre of Excellence for 21st Century Weather, aiming to understand how Australia’s weather will transform as our climate changes.
The rAM3 model is specially designed to run on the National Computing Infrastructure (NCI) platform available to the Australian research community.
The Australian focus of this release has been enhanced by a new functionality introduced by ACCESS-NRI, an improvement of the soil moisture initialisation using ERA5-Land from the European Centre for Medium-Range Weather Forecasts (ECMWF) and the BARRA reanalysis from the Bureau of Meteorology.
The future for the next versions of the ACCESS regional model will be to connect the Australian developed land-surface model, CABLE, as it better represents Australian vegetation and soil. Currently, ACCESS-rAM3 uses the UKMO land-surface model JULES.

Acknowledging the use of ACCESS-rAM3
Users of ACCESS-NRI models, data, tools of expert support are required to clearly include an acknowledgement in all publications/reports/public releases. Correct acknowledgement allows us to demonstrate our impact, find how our infrastructure is being used, and increase recognition of value of the ACCESS National Research Infrastructure. We suggest to use the following statement:
“This research used the ACCESS-NRI’s model ACCESS-rAM3, which is enabled by the Australian Government’s National Collaborative Research Infrastructure Strategy (NCRIS)”
ACCESS-NRI modelling relies on computational and data resources operated by Australia’s National Computational Infrastructure (NCI). ACCESS-NRI and NCI are enabled by the Australian Government, Department of Education, through the National Collaborative Research Infrastructure Strategy (NCRIS)
How is rAM3 used?
rAM3 enables researchers to understand extreme weather events like hurricanes, floods and droughts, which are not captured by the wide-angle lens of global climate models.
