NCI Data Collections BARPA & BARRA2 Overview
NCI Data Collections BARPA & BARRA2 serve as critical enablers of big data science and analytics in Australia, offering a vast research collection of climate, weather, earth systems, environmental, satellite, and geophysics data. These collections include around 8PB of regional climate simulations and are the first two CMIP6-era regional climate downscaling data sets released at NCI. Hosted at NCI, these services provide high-performance data storage co-located with high-performance computing facilities, specialized environments for data analysis, and access to various data services. Users can browse, search, and access datasets through the NCI Data Catalogue, which offers detailed metadata, persistent URLs, and information on data licensing and terms of use. Explore the rich repository of BARPA & BARRA2 data for a deeper understanding of Australia's climate and environmental systems.

NCI Data Collections BARPA & BARRA2 A critical enabler of big data science and analytics Australia s largest research collection of climate, weather, earth systems, environmental, satellite, and geophysics data. Around 8PB of regional climate simulations in preparation, and growing BARRA2/BARPA are the first two CMIP6- era regional climate downscaling data collections released at NCI. nci.org.au 2
