  1. Martin Schultz IEK-8 Forschungszentrum Jülich GmbH Rudy Husar Washington University St. Louis

  2. Air Quality • Many different species are air pollutants (particles, ozone, SO2, VOCs, POPs, mercury) • Air pollution is generated locally • Impacts of air pollution are diverse (health, crops, ecosystems, climate) • Regulations on air quality are diverse (different thresholds, dose functions) • Air pollution has global implications (long-range transport, long-lived species)

  3. Example for long-range transport of air pollution

  5. Which level of coordination is necessary/possible? NETWORK NETWORK? NETWORK NETWORK? Practice GEOSS is (should be) about: • producing data • distributing data • enhancing data • visualizing data • using data

  6. Air Quality Data Portals • ACTRIS - Aerosols, Clouds, and Trace gases Research InfraStructure • EARLINET - European Aerosol Research Lidar Network • EUSAAR - European Supersites for Atmospheric Aerosol Research • CLOUDNET • AeroCom - Aerosol Model Inter-comparison Project • CEOS ACP: Atmospheric Composition Portal • CIERA: Community Initiative for Emissions Research and Applications • DataFed - Federated Data Systems for AQ Data Access and Analysis • EBAS - Norwegian Institute of Air Research • GMES MACC: Monitoring Atmospheric Composition and Climate • Jülich MACC and HTAP boundary condition server • NASA GIOVANNI - Data & Information Services Center • US EPA RSIG - Remote Sensing Information Gateway • US EPA AQS - Air Quality System • VIEWS - Visibility Information Exchange Web System • World Data Centers (WDCGG, WOUDC) ? Notes: few „operational“ systems; little realtime data; poor links between systems; no data portal in Asia, Africa, South America, Australia

  10. Data formats (examples) WDCGG, Japan EMEP, NILU CASTNET, US

  11. Ensuring data quality Mean value at this station is ~30 (ppb), valid range = 1 – 40 ppb

  12. Ensuring data quality • requires (common?) data quality objectives • requires knowledge about data generation • must be standardized • across compounds • across measurement networks • across measurement techniques/instruments • across communities Can it be automated?

  13. Forming a community & Establishing practices
