1. Air Quality Management: Workflow, Value-Adding Activities, Participants and Earth Observation Needs R. Poirot, W. White, S. Falke, M. Schulz., K Hoijarvi, K. Torsett, E. Robinson, J Husar CoP Contact: R. Husar Oct. 5, 2010 DRAFT

2. Background AQ Management (AQM) and Science relies on a range of on Earth Observations (EO) form in-situ and remote sensing platforms. The the procedures and the outcome of AQM are defined by laws and regulations in most countries including the workflow/activities, the key participants and their respective needs. Hence, AQM is a suitable application area of the Global Observing System of Systems (GEOSS) where the user needs are satisfied by services offered. This is an initial attempt to formulate EO needs of AQM. The AQ Community of Practice is invited to contribute to this effort.

3. AQ Management: Science View Earth Observations are are most needed for quantifying pollutant emissions, transport and ambient concentrations User Types: Emission Analysts, Modelers, AQ Data Analysts

4. GEOSS Information Flow Framework Policy Maker Policy Analyst AQ Domain Analyst AQ Analyst Modeler AQ Management: Information Flow View GEOSS Core The AQ Information system processes Earth and other observations into actionable knowledge for policy/decision makers. User Types: AQ data analysts and modelers; health, aquatic and other domain analysts, policy analysts and policy/decision makers

5. AQ Management: Process View Backmann, Scheffe

6. Approach to Define EO Needs for AQM 1.Use the Process View to identify the workflow steps 2.For each step, list the respective required activities 3.Identify the participants who perform the activities 4.State their respective needs for EOs, tools and methods Structure Consistent with: GEO Task US 0901a: Priority Earth Observations for AQ GEOSS Clearinghouse/AQ Community Catalog User Requirement Registry Define needs using the open GEOSS AQ Community of Practice
