General Description of Atmospheric Model Evaluation Network (AMEN)

Drawing from the GEO Work Plan (Task DA-09-02d)Task

Demonstrate the use of web services to compare global and regional atmospheric models (including atmospheric chemistry/air quality models). Apply to a variety of Earth observations from distributed archives using standardized approaches to evaluate and improve model performance. Draw upon and contribute to the work of the Task Force on Hemispheric Transport of Air Pollution under the Convention on Long-range Transboundary Air Pollution, the IGAC-SPARC Atmospheric Chemistry and Climate Initiative, AeroCOM, and the Air Quality Model Evaluation International Initiative.

Keating 2009:

Questions from the GEOCAPE Science Traceability Matrix

What are the emissions of gases and aerosols important for

air quality and what are the processes controlling these emissions?

How do atmospheric transport, chemical evolution, and

deposition determine tropospheric composition over scales ranging from urban to continental?

How do we improve air quality forecast and assessment

models?

How do changes in air quality drive climate forcing on a

continental scale?

How does intercontinental transport affect air quality?

Learning more from EOS, Applying lessons to GEOCAPE

The Air Quality Community is just starting to embrace the use of observations from EOS instruments (due in large part to the work of the NASA Air Quality Applications program).
As the AQ Community begins to build the infrastructure and capacity to use this information, it is based on the current suite of EOS instruments and datasets – what continuity will there be with GEO-CAPE?
The AQ Community consists of a wide spectrum of users with different needs and different capabilities to access and use the data.
What lessons can be learned from the current applications of EOS data products regarding data availability, data coverage, data formats, data accessibility, and data

quality?

Proposed Workshop Series on Satellite Observations in Air Quality Management

Engage a broader air quality management community: States, Academics, Private Sector Stakeholders
Opportunity for two-way communication between Air Quality and Satellite Communities
Not just about GEO-CAPE, but also about what can be done with the current stream of satellite observations.
Beginning of a longer-term process that we hope will continue as the mission develops and comes to fruition

GEOSS: A Technical Initiative

GEOSS is built around a minimal central clearinghouse and other components of a Common Infrastructure. This GCI is not to house data or tools for using data – it is used to enable users to find that data.

GEOSS registries are flexible enough to work with ‘any’ observation, so metadata will be less than needed for many users.

Community catalogs and portals are response this a to need for a richer access point, tuned for a particular user community.

GEOSS is about decision support. The GCI won’t provide that. It is set up as a base for service oriented architecture which will in turn improve decision support.

Architecture Implementation Pilot Output

AIP charge: produce ‘persistent exemplars’ to develop GEOSS

Air Quality The AIP AQ work group is building an AQ community infrastructure to compliment the GCI

Future for EPA GEO Air Theme: Developing an Air Quality Cyberinfrastructure “Consortium”

Need a team capable of linking and extending the existing elements of the air quality information system to create a stable cyberinfrastructure (hardware, software, standards, organizations, …).
Expertise needed in
- air quality forecasting and public information
- air quality assessment or “re-analysis”
- air quality model evaluation and intercomparison
- emissions inventory development and evaluation
- fire and smoke management
- cyberinfrastructure development

Some Possible Tasks for the Consortium
Air Quality Information System Wiki
- Identify functions, strengths, weaknesses of, and relationships between existing air quality information systems
- Develop consensus guidelines
Air Quality Data Network Development
- Establish a community data and service catalogue specific for air quality information, establish exchange standards for creating connections between existing elements of

the air quality information system of systems, and implement such connections.

Air Quality Assessment Tools
- Processing, visualization, and analytical tools for air quality assessment, or “reanalysis,” in which multiple types of observations and/or model estimates (drawn from across the air quality data network described above) are integrated to best describe the state of the atmosphere at a given point and time.
Air Quality Model Evaluation Tools
- Tools that will enable modelers to compare regional and global model outputs in standard formats to a variety of types of observational data (drawn from across the air quality data network) and to perform standard tests and diagnostics.
Emissions Information and Tools
- Building upon NEISGEI, EMF, and related systems.
Outreach and Coordination
- Organize meetings and other outreach efforts to educate and communicate with the broader air quality management and research community
