The document discusses the GEOSS (Global Earth Observation System of Systems) architecture for the air quality community. It proposes an architecture where air quality services could register with the GEOSS registry and be discovered and invoked by users. This would allow data analysts to compose and visualize air quality data workflows to inform decision makers. It also discusses establishing an air quality community of practice to facilitate collaboration.

Programs analyze the data and provide actionable knowledge to organizations. Organizations evaluate multiple information sources, make decisions and act. Flow of Control Public and special interest groups set up organizations and provides them with funding Organizations develop programs, define their scope, governance and funding Programs satisfy their information needs by monitoring or by using other’s data Data sources acquire the data for their parent programs and also expose them for reuse
