1. Global Earth Observation System of Systems (GEOSS) Architecture Implementation Pilot (AIP) Air Quality and Health Working Group Stefan Falke, Rudy Husar, Frank Lindsay, David McCabe, Erin Robinson

2. Air Quality & Health Scenario Scenario Overview The AQ Scenario envisions multiple types of AQ observations… 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 community-developed ; AIP participation diverse (next slide) Initial sub-scenario testing AIP Use Cases describes a Wildfire/Smoke event 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
