ACCESS-NRI, Australia's climate simulator, is a national research infrastructure created to support development and research with the Australian Community Climate and Earth System Simulator (ACCESS) modelling system framework. ACCESS simulates past, present and future climate, weather and Earth systems.

Our models simulate different future weather and climate scenarios by linking separate computer modules that represent different parts of the Earth system such as the atmosphere, land, ocean, and sea ice.

Our models are powerful tools for researchers. They provide weather and climate predictions at all time scales to support decision making in agriculture, water, emergency management, planning for public infrastructure, and more.

ACCESS-NRI is a major collaborative undertaking between the Bureau of Meteorology, CSIRO, Australian Antarctic Division, and five Australian universities, in collaboration with national and international partners.
