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

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

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

1: Publish and register data services

Key message: Simplifying the process for air quality data providers to use the GEOSS

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

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

• Facilitation of Market Supply demand

• Global Broker• Improved Find by metadata• Easier Registration

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

18

Find data and tools

Search for wildfire/smoke/AQ services and clients/tools via AQ Community Portal and Applications

19

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

20

4. Interoperability of GEO Information System

Key message: Data Access services provide software interop; Standard metadata provide

Humanware interop
