    • 1. Interoperable Information System of Systems for HTAP Rudolf B. Husar and Rich Scheffe With Erin Robinson Presented at HTAP Workshop, WMO, Geneva, January 26, 2006
    • 2. Intercontinental Transport Events have Influenced AQ Regulations ..and now Policy? –> Air Quality Management Web-Based Collab. in Virtual Workgroups –> Science, the Process Near-Real-Time Data Access & Integration –>Technologies and Tools US-Daily Avg. PM25 Dust: Seasonal + Events
    • 3. HTAP Characteristics
      • Stakeholders are autonomous countries, organizations
      • Diverse perspectives on the issues, solutions
      • Pollution sources and impacts are hemispheric
      • Information integration is key to success
      • Observations and models are ready for integration
    • 4. The HTAP - GEOSS
      • Stakeholders are autonomous countries, organizations
      • Diverse perspectives on the issues, solutions
      • Recognition of the need to understand, act
      • Pollution sources and impacts are hemispheric
      • Observations and models are ready for integration
      • Information integration is key to success
      • Hence
      • GEOSS is a good system model for HTAP
      • HTAP is a suitable use case for GEOSS
      • Some Characteristics of System of Systems (SoS)
      • Autonomous constituents managed independently
      • Independent evolution of each constituent
      • Displays emergent (novel, unpredictable) behavior
    • 5. Summary
      • There is an ‘ alignment of stars ’ for integrating heterogeneous HTAP data
      • System of Systems architecture is suitable for integrating HTAP data
        • Standard data access is a key interoperability protocol
        • Heterogeneous data can be non-intrusively standardized by mediators
        • Service-based software architecture delivers tailored products to diverse uses
      • Federated data and shared web-based tools are in use
        • DataFed already includes over 100 datasets (emissions, ground, satellite)
        • The system has been applied to EPA regulatory development
      • However,
        • DataFed is just one of the many mediator nodes, but these need to be connected
        • Much more data would need to be federated
        • HTAP model-data comparison would be an attractive use case
      • WMO-GAW could be an effective neutral facilitator for global data integration using GEOSS (system of systems) principles
    • 6. GEOSS Architecture Framework - DSS for HTAP Observations HTAP Knowledge into the Minds of Policy Analysts HTAP Reports: Model Estimates, Obs. Evidence Models Knowledge into the Minds of AQ Analysts Decisions HTAP Knowledge into the Minds of Policy Makers Decision Support System GEOSS Architecture Framework
    • 7. System of Systems: Interoperability Connecting Machines and People IP – Internet Protocol Open Architecture Data Standards Service Based Amplify Individuals Connect Minds Interoperability Stack: Key concept of the Web System components have to be interoperable at each layer
    • 8. How do you agree on Interoperability?
    • 9. What few things must be the same so that everything else can be different? Are WCS/WMS Space-Time-Parameter queries Convergence Protocols T2 T1 WCS/WMS App App App App GetCapabilities GetData Capabilities, ‘Profile’ Data Where? When? What? Which Format? Server Back End Std. Interface Client Front End Std. Interface CF, EOS, OGC CF OGC, ISO OGC, ISO Standards netCDF, HDF.. Format Temperature What? Time When? BBOX Where? GetData Query
    • 10. Lets agree on Space-Time-Parameter Data Access Query Protocol
    • 11. From ‘Stovepipe’ to Federated Architectures Scientist Science DAACs
      • Current info systems are project/program oriented and provide end-to-end solutions
      Info Users Data Providers Info System AIRNow Public AIRNow Model Compliance Manager
      • Part of the data resources of any project can be shared for re-use through DataFed
      • Through the Federation, the data are homogenized into multi-dimensional cubes
      • Data processing and rendering can then be performed through web services
      • Each project/program can be augmented by Federation data and services
    • 12. Web Services and Workflow for Loose Coupling Integrated Data Datasets Std. Interface Data Views Std. Interface Data Control Reports Reports Obs. & Models Decision Support System Service Broker Service Provider Publish Find Bind Service User Web Service Interaction Service Chaining & Workflow
    • 13. Collaborative Reporting and Dynamic Delivery Integrated Data Datasets Std. Interface Data Views Std. Interface Data Control Reports Reports Obs. & Models Decision Support System Analysis Reports: Information supplied by many Needs continuous program feedback Report needs many authors Wiki technologies are for collaborative writing Dynamic Delivery: Much of the content is dynamic Animated presentations are compelling Movies and screencasts are for dynamic delivery Co Writing - Wiki Screencast
