The Earth System Grid (ESG) project makes climate simulation data easily accessible to the climate modeling community.
The envisioned topology of the ESG enterprise system with 100-gigabit per second (Gbps) network connections and cloud computing will provide a network of geographically distributed gateways, data nodes, and cloud computing in a globally federated, built-to-share scientific discovery infrastructure. In this way, independent data warehouses can deliver seamless access to vast data archives so that scientists can deploy specialized client applications for extreme analysis.
The goals of the a Livermore National Laboratory project called "Scaling the Earth System Grid to Petascale Data Center for Enabling Technologies" are to accomplish the following:
- Sustain the successful existing ESG system
- Address projected scientific needs for data management and analysis
- Extend the ESG system to support the major Intergovernmental Panel on Climate Change assessment in 2013
- Support the Climate Science Computational End Station at the U.S. Department of Energy's Leadership Computing Facility at Oak Ridge National Laboratory
- Support climate model evaluation activities under the proposed SciDAC-2 climate application
ACTIVITY DESCRIPTION AND TEACHING MATERIALS
The Earth System Grid (ESG) project was developed by a team of researchers from national laboratories (ANL, LANL, LBNL, LLNL, and ORNL), federal research centers (NCAR, NOAA/PMEL), and the University of Southern California to make climate simulation data accessible to the international research community
Periodically, the ESG system is upgraded to meet the needs of future Intergovernmental Panel on Climate Change (IPCC) assessment reports.

TEACHING NOTES / CONTEXT FOR USE
Experts (e.g., model developers, climate researchers) and non-experts alike will benefit from rich data exploration and manipulation available with such fault-tolerant, end-to-end system integration.

Assessment is at the discretion of the educator and how the data sets are used.

This site is funded by the U.S. Department of Energy. The Earth System Grid (ESG) project integrates supercomputers with large-scale data and analysis servers located at numerous national laboratories and research centers to create a powerful environment for next generation climate research.
In March 2010, ESG had 2,300 registered users and managed 140 terabytes of data. It is estimated that more than 200 scientific publications are under way from analysis of ESG-delivered data in the year 2009 alone. Despite these successes, ESG faces significant challenges in coming years as the size, complexity, and number of climate data sets grow dramatically.
