15. NSF-NOAA-EPA/EMAP (NASA)? Project: Real-Time Aerosol Watch System Real-Time Virtual PM Monitoring Dashboard. A web-page for one-stop access to pre-set views of current PM monitoring data including surface PM, satellite, weather and model data. Virtual Workgroup Website. An interactive website which facilitates the active participation of diverse members in the interpretation, discussion, summary and assessment of the on-line PM monitoring data. Air Quality Managers Console. Helps PM managers make decisions during major aerosol events; delivers a subset of the PM data relevant to the AQ managers, including summary reports prepared by the Virtual workgroups.

32. DataFed Topology: Mediated Peer-to-Peer Network, MP2P Mediated Peer-to Peer Network Broker maintains a catalog of accessible resources Peers find data and access instructions in the catalog Peers get resources directly from peer providers Google Example: Finding Images on Network Topology Google catalogs the images related to Network Topology User selects an image from the cached image catalog User visits the provider web-page where the image resides Source : Federal Standard 1037C Mediator Peers
