DESCRIPTION
The EarthGrid network gives researchers from around the world seamless and persistent access to shared environmental data that are valuable for synthesis and analysis. Researchers use a consistent system to locate and download datasets housed in disparate, loosely-coupled repositories that have committed to providing a standard communication interface. Evolution of the existing EarthGrid network is underway to increase the breadth and depth of available data.
