4/5 May 2009 The Palazzo dei Congressi di Stresa Stresa, Italy 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 4/5 May 2009 The Palazzo dei Congressi di Stresa Stresa, Italy

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

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

Publish Service Metadata Scenario Standards Components: Provider – User – Broker Actions: Register– Discover - access Service Broker Service Broker Find Services Get Access Key Publish Service Metadata The GEOSS Information Systems operates through The AQ community has adopted the standard data access service interface for all datasets and follows the service oriented publish-find-bind approach. Service User Access Service Provider 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

1: Register data services Key message: Simplify the process for air quality data providers to use the GEOSS Common Infrastructure

Deploy OGC W*S Service Service Broker Service User WCS/WMS Servers GetCapabilities Service User WCS/WMS Servers WMS Validator 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 19115 records can be made semi-automatically starting with WMS or WCS get capabilities and other ISO 19115 records using the metadata editor Additionally, client applications can create ISO 19115 records by using the AQ ISO 19115 Schema to translate their dataset records into ISO 19115 records. Once the metadata has been created, it is saved into the Community Catalog Web Accessible Folder. 3 sets of standards does interoperability.

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

Create and Register Metadata Air Quality Community Catalog ISO 19115 ISO Validator GetCap to ISO Translation Get Capabilities Needs to be machine gears First condition is that all of air quality datasets are standards based data access with wms and wcs Creating AQ ISO 19115 records can be made semi-automatically starting with WMS or WCS get capabilities and other ISO 19115 records using the metadata editor Additionally, client applications can create ISO 19115 records by using the AQ ISO 19115 Schema to translate their dataset records into ISO 19115 records.

Registration with AQ Community Catalog Web Accessible Folder Registration via GetCapabilities to ISO 19115 translation

Service Broker Harvest Service Service User Provider ISO 19115 GEOSS Clearinghouse(s) Community Catalog ISO 19115 The Community Catalog, GEOSS registry and GEOSS Clearinghouse make up the service broker. The Community Catalogs are registered in the GEOSS registry the clearinghouse searches the registry to find catalogs and then harvests the catalogs for the service metadata records Service User Service Provider

AQ Dataset Registration Metadata ISO 19115 OGC CSW Core Queryable Air Quality Specific ISO 19115 CSW Profile Returnable Metadata Description 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.

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

Service Discovery Service Broker Service Broker Service Broker Service OGC CSW Core Queryable ISO 19115 AQ Portal/ Apps The addition of the GEOSS common infrastructure enhances the service broker by allowing easier publishing through the community catalog for the service provider and improved finding for the service user.

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