| Purpose | The Earth System Grid Federation provides a distributed platform to store, manage, and distribute petabyte-scale climate model data for global research. It supports climate science by ensuring open, secure access to simulations and observations, notably for the Intergovernmental Panel on Climate Change assessments. |

The Earth System Grid Federation (ESGF) is an international, multi-agency initiative that delivers a robust, decentralized infrastructure for accessing and analyzing massive climate datasets, critical to advancing global climate research. Originating from the Earth System Grid in the late 1990s, ESGF formalized in 2004 as a partnership led by the Department of Energy alongside NASA, NOAA, and international collaborators, hosting over 45 petabytes of data for more than 40,000 users across six continents.[1] It underpins major efforts like the Coupled Model Intercomparison Project (CMIP), powering IPCC reports with peer-to-peer data nodes that prioritize transparency and reproducibility in climate science.
Goals
- Enable seamless access to petascale climate data for researchers worldwide.
- Support reproducible climate science through standardized data protocols and tools.
- Facilitate high-resolution Earth system modeling, targeting improved climate projections.[2]
Organization
The Earth System Grid Federation operates as a partnership, with leadership from the Department of Energy’s Oak Ridge National Laboratory (ORNL), alongside Argonne and Lawrence Livermore National Laboratories, and international nodes in 17 countries. Governance is decentralized, managed by an Executive Committee of representatives from key institutions, with Forrest Hoffman, Computational Earth Sciences group lead at ORNL, serving as the U.S. Project Lead.[3] Funding stems from DOE’s Office of Science, NASA, NOAA, NSF, and European partners, supporting node operations and software development.

History
ESGF evolved from the Earth System Grid, initiated in the 1990s to manage climate model outputs, transitioning into a federated system by 2004 to meet growing data demands.[4] It gained prominence supporting CMIP phases, including CMIP5 and CMIP6, which informed IPCC’s Fifth and Sixth Assessment Reports. A 2020 roadmap spurred the ESGF2 project, launched in 2022, to enhance scalability and usability, leveraging exascale computing and cloud resources. The program continues to expand, adapting to rising data volumes and complexity with no planned end.
Funding
Initial funding in 2004 came from multi-agency contributions, including DOE, NASA, NOAA, and NSF, though specific amounts were not detailed publicly. Ongoing support flows from these U.S. agencies, European partners like IS-ENES, and over 50 global institutions, with recent ESGF2 efforts backed by DOE’s Biological and Environmental Research program.[5] Funding sustains data replication, node maintenance, and upgrades, with no fixed termination date.
Implementation
ESGF operates through a peer-to-peer network of data nodes hosted globally, using open-source software to distribute climate simulations like those from the DOE’s Energy Exascale Earth System Model.[6] Implementation involves phased upgrades, with ESGF2 (started 2022) enhancing data access via cloud computing and DOE’s Energy Sciences Network. It’s an ongoing effort, continuously improving to handle increasing data scales without a set end date.
