a community-based framework for sharing data

This presentation will discuss tools and techniques available today for greatly improved access to model outputs over the Internet. Most interchange of model outputs still occurs today via file transfers, typically via FTP. File transfers require the recipient to become a participant in the time consuming business of data management -- dealing with storage of large files, multiple formats, and data content that may be spread across many files (e.g. a time series). The community is recognizing and utilizing new tools through which scientists may view and obtain precise subsets of data directly from the provider's site while remaining wholly insulated from these barriers. These tools facilitate much higher levels of collaboration, opening the door to community-wide model intercomparison. Recent additions to the tools are bringing real time and historical observations into the mix, as well. Several groups are capitalizing on the use of these tools, including GODAE (Global Ocean Data Assimilation Experiment), NVODS (National Virtual Ocean Data System), NOMADS (NOAA Operational Model Archive and Distribution System), various "MIPs" (model intercomparison projects), and the "Data Grid" (Dept. of Energy et. al.)
