Minisymposium Presentation

Earth system data's exponential growth presents opportunities and significant challenges for Earth System science research. The presentation outlines NSF NCAR's implementation of the Next-Generation Geoscience Data Exchange (NG-GDEX), a data commons architecture, alongside on-premise cloud computing resources, complementing our existing HPC and data analysis infrastructure. NSF NCAR aims to remove technical barriers that impede participation in Earth system science across institutional and geographical boundaries. Our long-term goal is to deliver data to the scientific community when needed and in the format they want. Our approach unifies currently siloed repositories while integrating with the Open Science Data Federation (OSDF) to democratize access to petabyte-scale Earth System science models and observational datasets. We will describe our approach to making high-demand datasets directly accessible from our HPC systems, enabling researchers to leverage data-proximate computing without unnecessary data movement. NSF NCAR is committed to prioritizing community needs and is working on implementing our data commons workshop recommendations. We aim to break down barriers, enhance reproducibility, and foster a more inclusive and collaborative global research environment.
