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

Stresa, Italy

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 GEOSS Common Infrastructure: Community Catalog, Portal
Implementing scenarios which can integrate the offerings using GCI-compatible Service Oriented Architecture 2

4. 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

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

Dataset
A data provider deploys a standards based data service.
Make smaller -
First condition is that all of air quality datasets are standards based data access with wms and wcs
Creating AQ ISO records can be made semi-automatically starting with WMS or WCS get capabilities and other ISO records using the metadata editor
Additionally, client applications can create ISO records by using the AQ ISO Schema to translate their dataset records into ISO records.
Once the metadata has been created, it is saved into the Community Catalog Web Accessible Folder.
3 sets of standards does interoperability.

10. Discover GEOSS Community Components
A data service provider searches the GCI for air quality community resources to help with GEOSS registration and finds the GEOSS AQ Community Catalog and GEOSS AQ Community Portal

Data Access
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
Developed AQ Metadata Record using ISO 19115
The record has three parts
OGC Core Queryable and returnable fields which are the key parameters for discovery common to all earth obs
Also include the Data Access Key, commonly a getCapablilities link to allow users to bind to the data
The additional metadta in the yellow and blue boxes allows users to refine search/discovery before they bind to the data.
