ACCESS-NRI, Australia’s Climate Simulator, would like to invite you to the ACCESS Community Workshop 2025.
Climate, weather and Earth system models play a crucial role in understanding and predicting the Earth’s climate system. The annual ACCESS Community Workshop aims to provide a platform for knowledge sharing and interdisciplinary collaboration around the science that uses the ACCESS models to address the complex Earth system challenges that Australia faces.
The main aims of the workshop are to build the ACCESS community by bringing together technical experts and researchers and drive collaborations on new ACCESS developments and to provide a welcoming environment for early career researchers and students.Everyone is welcome, especially students and early career researchers.
This is an opportunity to share your challenges and successes from working with the ACCESS models, exchange innovative uses of the models and experiences with others in the community, and enhance existing links specially between disciplinary areas.
WHERE AND WHEN
This year, the main Workshop will be held in Melbourne Connect, VIC on the traditional lands of the Wurundjeri Woi Wurrung people of the Kulin Nation. Join us for an exciting week of events including:
