3. IGOS Architecture Mapped to DataFed The Len Barrie Challenge Not part of DataFed Quality assurance, CalVal? Integrated Data Archives? - Special Architectural Features: Real-time data assimilation into AQ models Characterization of global pattern Forecast Weather & Air Quality Implement IGACO–LRTAP by inviting WMO, UNEP and appropriate regional programmes to: Establish an IGACO-LRTAP implementation secretariat. Conduct an international pilot project to develop and implement a mechanism to assemble a comprehensive “screened” global atmospheric composition data base relevant to surface ozone and PM air quality, human and ecosystem health and deposition effects. Work with WMO to deliver data to weather and air quality forecasters in real time through its well established Global Telecommunications System (in future WIS) and other mechanisms.
