• Air Quality Management (AQM) and Science relies on EOs for emissions, transport and ambient concentration of air pollutants.
• The required EOs are obtained mostly by the AQM Agencies themselves, using in-situ sensors and monitoring networks.
Earth Observations and Air Quality
However, •AQM-relevant EOs are only available for small regions of the world•There also need to include emerging remote sensing and AQ model data.•There is a need to integrate and reconcile the existing diverse observations
GEOSS Goal:
Facilitate access and integration of a broad range of EOs to SBAs, including Air Quality
Users and Scientific Communities Served ByGEOSS Common Approaches Systems within their Mandates
Success begins and ends on this side of the architecture
UserRequirements
In order to facilitate Ongoing feedback to optimize value and reduce gaps in GEOSS,
this is an initial, limited attempt to formulate a methodology for determining the User Requirements for EOs for Air Quality Management
Foley et. Al, UIC, May 2008
Methodology for Gathering User Requirements:
1. State the SB Sub-Area: e.g. Manage Air Quality 2. Define Major Workflow Steps of the SBA3. Name the Value-Adding Activities4. Identify Participants for Each Activity (i.e. the ‘Users’)5. Determine the Participant’s EO Needs
The methodology is a ‘bottom up’ approach.Decomposes the AQM process into workflow steps and specific activitiesEO needs are determined by the activities and the participating ‘users’ who perform those activities
US-09-01a and Current Method are Complementary Approaches
US-09-01a Nine-Step Method for Priority Eos
1: Identify Analyst and Advisory Group for the SBA 2: Determine scope of topics within the SBA 3: Identify docs on obs. priorities for the SBA 4: Develop analytic methods and priority criteria 5: Analyze docs for priority EO needs6: Combine the info. and develop a prelim. report 7: Gather feedback on the preliminary report 8: Perform any additional analysis 9: Complete the report on Earth obs. for the SBA
Developed Five-Step Methodology for User Requirements
1: State the SB Sub-Area: e.g. Manage Air Quality 2: Define Major Workflow Steps of the SBA3: Name the Value-Adding Activities4: Identify Participants for Each Activity (‘Users’)5: Determine the Participant’s EO Needs

Requirements
The URR is a facility for collection, sharing and describing:• User types among the nine SBAs;• Applications that use Earth observations;• Requirements for Earth observations and derived products; • Links among user types, applications, and requirements.
The Method is compatible with the GEO User Requirements Registry (URR)

Strengths and Weaknesses of the Method
Strengths •It is ‘observation-based’, using the actual activities, and EO uses•Is methodical, so it can be broadly applied as a pattern•The EO needs can be expressed in the same way as EO offerings
Weaknesses•Method is tedious, requires detailed workflow, users, their EO needs•Applicable to well-established AQM activities, not for ad-hoc uses•Not tested for different environments and problem domains
EO Prioritization not yet considered•EO prioritization by this method is a multi-faceted, subtle activity•Not yet addressed by the GEO AQ CoP
