  • My name is Rudy Husar from Washington University. This is a report on the HTAP Data Network with illustrative applications to NOx analysis. The collaborators on this work represent the initial nodes of the emerging HTAP Data Network: Stefan Felke of Northrop Grumman Corp and WashU, Greg Leptoukh of NASA Goddard and Martin Schultz form the Forschungszentrum Juelich.

  • 2. 2007 HTAP Interim Report
    • Models, observations, emissions have been assessed
    Model Outputs Observations Emissions Emission Integration Emission comparisons, reconciliation Model Comparisons Model-model comparison, ensemble, Data Integration Data homogenization and integration
  • 3. 2009 HTAP Assessment
    • Seek the reconciliation of models, observations, emissions
    Model Outputs Observations Emissions Emission Integration Emission comparisons, reconciliation Model Comparisons Model-model comparison, ensemble, Data Integration Data homogenization and integration
  • 4. 2009 HTAP Assessment
    • Reconciliation is through the interaction of domain experts
    • Can benefit from a network for the seamless flow of data/info

    • The goal of HTAP Network:
    • Connect the data nodes
    • Enable with shared tools
  • 6. Initial HTAP Data Flow Network Loosely Coupled Data Network of Autonomous Nodes OGC WCS Data Access Protocol
  • 7. Application of OGC WCS Data Access Protocol
    • Regardless of the data location, data type and format,
    • the parameter-space-time query is the same
    • the return is in user selectable format from the offerings
