1. 1 Using the GEOSS Common Infrastructure in the Air Quality & Health SBA: Wildfire & Smoke Assessment Prepared by the GEOSS AIP-2 Air Quality & Health Working Group May 2009

2. 2 Air Quality & Health Scenario Scenario Overview The AQ Scenario envisions integration of multiple types of AQ data… satellite observations of AQ and meteorology in-situ, ambient observations models of meteorology and chemical transport other: emissions data, fire observations, LIDAR, etc. …being registered, discovered and accessed via GEOSS and used to inform diverse decision-makers: Air Quality Managers, Policy-Makers, and the Public. Scenario is community-developed and community-evolved Challenges Persistent, standardized AQ data network Interface to GCI: Community Catalog, Portal Implementing scenarios which can integrate the offerings using GCI- compatible Service Oriented Architecture

3. 3 Wildfire & Smoke Scenario Test and evaluate GEOSS architecture with a focused scenario Find and use fire location, air pollution observation, and smoke model forecast data to assess air quality impacts of a wildfire event Focus on the 2007 Southern California Fires

4. 4 1: Publish and register data services Key message: Simplifying the process for air quality data providers to use the GEOSS Common Infrastructure

5. 5 Service Oriented Architecture Service Broker Service Provider Publish Service Metadata Access Service User Components:Provider – User – Broker Actions: Register– Discover - access Find Services Get Access Key Service providers register service metadata to a service broker. Service users find the needed service and get access key from a service broker With the access key, users bind to the service provider The result is a dynamic binding mechanism between the service users and providers

8. 8 AQ Dataset Registration Metadata ISO 19115 AQ Metadata has two parts: –Data Access –Discovery The Discovery metadata includes –Elements that are required for all Earth Observations –Additional elements to ISO 19115 –AQ Specific elements OGC CSW Core Queryable Air Quality Specific ISO 19115 CSW Profile OGC CSW Returnable Metadata Description Data Access

19. 19 2: Search and find data services and tools Key message: Standard metadata and search interfaces allow multiple tools to find air quality data from a common metadata pool

20. 20 Find data and tools Search for wildfire/smoke/AQ services and clients/tools via AQ Community Portal and Applications

21. 21 3. Interacting (binding) with distributed data Key message: Multiple tools for visualization and analysis can each uniquely work with a shared, common pool of data resources

22. 22 4. Interoperability of GEO Information System Key message: Data Access services provide software interop; Standard metadata provide Humanware interop

23. 23 Services Service Broker Service Provider Service User Components:Provider – User – Broker Actions: Register– Discover - access Service providers register service metadata to a service broker.
