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
Approach: HTAP as a Learning Organization
Information System Approach:• Guiding Idea: Refine, solidify, evangelize the System of Systems idea• Methods and Tools: Develop, promote, use standards; SoS use cases• Infrastructure: Maintain middleware; embrace Web 2.0
Based on P. Senge et. al, 1994: Architecture of Learning Organizations(Link)
Guiding Idea: System of Systems
Methods, Tools: Standards, Use Cases
Infrastructure: Middleware, Web 2.0
Domain of ActionOrganizational Architecture
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 HTAPHTAP 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
Generic Decision Support for Air Quality Decisions

Interoperability: Connecting Machines and People

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
Interoperability – Necessary for SoS
What few things must be the same so that everything else can be different?

Characteristics of a 5D World
• The 5D World is Flat– Information is the primary driver for progress
– Time and place are no longer barriers to participation
– Access is open to specialists and non-specialists alike
• The 5D World is Expanding– New capabilities, resources, mechanisms
– More spaces for learning and innovation
– More opportunities for collaboration (emergence)
From GADS to IGOS/GEOSS Information Systems
Example

Recognize, exploit SoS Characteristics:
No stakeholder has complete SoS insightCentral control is limited -> distributedUsers involved throughout the life of SoS
Approach
Use and build on existing systemsTransform data to information for societyUse open standards, shared architecture
Imagine 1012 A 20-fold increase in Earth Science Capabilities?
• More Data 2x sensor x 6x networking = 12x• Powerful Tools 2x power x 3x workflow = 6x • Better Ideas 1x individ. x 2x group = 2x
Individually: 5x collectively: 20x
…again the confluence! Knowledge creation will be driven by the
combination of data, tools and ideas
Some changes will be driven by the digital revolution.. but the networking, workflow and group creativity
is in the hands of the
atmospheric science community
Imagine…More Shared Global Obs & Models
2012More Global Data & Models
2006Global Data & Models
Imagine…More Local Obs., Models, Knowledge
2012More Local Obs., & Models

Collaboration (culture) empire building?

Budgets, agency collaboration resource/program accountability

HTAP 2005 Workgroup Summary Goal: Advance AQ model-observation system to level of met FDDA systems
• General Approach– Build Organizational frameworks : IGACO-EMEP efforts– Adopt model evaluation/fusion as a design principle
• Harness communities around tools, platforms and programs – AQ modeling platforms (GEOS-chem, MOZART, CMAQ,….more), Satellite
Instruments (MODIS, OMI), Surface (AIRNow) and aircraft programs– Integration efforts (AEROCOM), Earth Science Information Partners (ESIP)
• Integration of disparate data bases– Integration & fusion of ground, aircraft and satellite obs. platforms)– Data base unification, QA/QC; Requirements; Metadata– Use cases: AeroCom, NAM model/obs comparison (2006-)
• Technologies (2006-):– Develop, testing of Convergence Protocols for SoS– Data access by space-time query (WCS)– Naming conventions (C. Textor)
