• The LRTP/HTAP flow of air pollutants is likely to increase as overseas economies grow.• Pollutant influx leads to significant exceedances of O3 PM NAAQS in some regions• Even after domestic controls, some US areas will be no-compliant because of LRTP

System of SystemsGlobal Earth Observing System of Systems - GEOSS
Characteristics of System of Systems (SoS)
• Autonomous constituents managed/operated independently
• Independent evolution of each constituent
• SoS displays emergent behavior
Must recognize, manage, exploit the characteristics:
• No stakeholder has complete SoS insight
• Central control is limited; distributed control is essential
• Users, must be involved throughout the life of a SoS

The Transformational Effect of Networking
“Networking has led to an unprecedented surge of productivity” Time Magazine, Person of the Year 2006, YOU
• These are opportunities to enable Earth Science through more networking
• But many resistances to networking exist that need to be overcome
• Information has become the main driver of progress• Time and place are no longer barriers to participation and interaction • The Web has become a medium participation - ‘Web 2.0’ phenomenon
![Page 19: 2008-02-11: EPA DataFed Presentation](https://reader033.vdocument.in/reader033/viewer/2022061222/54c1bff74a7959a2208b456f/html5/thumbnails/19.jpg)

Summary
There is a slow ‘aligning of stars’ for integrating heterogeneous data
• System of Systems architecture is suitable for integrating 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 policy, regulatory and science 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

Numerous state, regional, and national fire related databases and online access applications exist. The challenge is to bring them together, on-the-fly, without requiring substantial changes to the underlying systems.
Also need to access data sources that are not “Web-ready”.

Summary
• Global Monitoring - Modeling Revolution – ‘May you live in interesting times’– We are in the midst of an observational revolution (satellites, monitoring networks).– The global distribution and transport of some pollutants can be monitored daily– Global models are maturing into effective analytical and predictive tools
• Results to Date: – Compelling evidence for global-scale transport of PM and Ozone– Qualitative evidence of ‘extra-jurisdictional’ impact on the US air quality– Potential for quantification of natural and non-US impact
• Such massive job will require:– International, interagency, interdisciplinary collaboration.– Open flow of data/knowledge– Scientific ‘value-adding chains’
![Page 44: 2008-02-11: EPA DataFed Presentation](https://reader033.vdocument.in/reader033/viewer/2022061222/54c1bff74a7959a2208b456f/html5/thumbnails/44.jpg)
FASTNET and DataFedFASTNET (Fast Aerosol Sensing Tools for Natural Event Tracking) an open communal information sharing facility to study aerosol events, including detection, tracking and impact on PM and haze.
The main asset of FASTNET is the community of data analysts, modelers, managers participating in the production of actionable knowledge from data and models
The community is supported by a non-intrusive data integration infrastructure based on Internet standards (web services) and a set of web-tools evolving under the federated data system, DataFed
DataFed is supported by its community and is under the umbrella of the interagency Earth Science Information Partners, ESIP (NASA, NOAA and EPA)
