Building a User-Driven GEOSS: Methods to Capture, Analyze, and Prioritize User Needs

Earth Observations and Air Quality
•
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.
•
•
•
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 By
GEOSS Common Approaches
Systems within their Mandates

UIC, May 2008
Success begins and ends on
this side of the architecture
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
Methodology for Gathering User Requirements:
1.

4.
5.
State the SB Sub-Area: e.g. Manage Air Quality
Define Major Workflow Steps of the SBA
Name the Value-Adding Activities
Identify Participants for Each Activity (i.e. the ‘Users’)
Determine the Participant’s EO Needs
The methodology is a ‘bottom up’ approach.
Decomposes the AQM process into workflow steps and specific activities
EO needs are determined by the activities and the participating ‘users’ who
perform those activities
US-09-01a and Current Method are Complementary Approaches
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 SBA
3: Name the Value-Adding Activities
4: Identify Participants for Each Activity (‘Users’)
5: Determine the Participant’s EO Needs

workflow and
accounting

Identify Analyst and Advisory Group for the SBA
Determine scope of topics within the SBA
Identify docs on obs. priorities for the SBA
Develop analytic methods and priority criteria
Analyze docs for priority EO needs
Combine the info. and develop a prelim. report
Gather feedback on the preliminary report
Perform any additional analysis
Complete the report on Earth obs. for the SBA

The Method is compatible with the
GEO User Requirements Registry (URR)
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.

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
