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

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
