    • Recommendations to Task Force
      • Major
        • Adopt model evaluation/fusion as a design principle
        • Challenge organizations to elevate transport as a primary objective (currently, secondary to climate, start. Ozone)
      • Identify key list of routine measurements and locations to support IT assessments
        • Gases (CO, NOy, NO2, SO2, HCHO, O3, Hg (species), CH4,VOCi)
        • aerosol components (EC, OC, S, N), mass/scattering
      • Support linkage of ground based and satellite observation platforms through development of a sustainable vertical profiling system (aircraft and ground based lidar)
      • Address integration of disparate data bases
        • QA/QC: provide requirements for data standards/metadata descriptions
        • Data base unification
    • United States Ambient Air Monitoring
      • >$100M annually (routine programs)
        • Does not include specific inflow/outflow stations
          • Value/resource allocation?
        • Anchored in 1970-80’s design model: inertial barrier
          • Multiple agencies, high concentration emphasis
      • Intercontinental Transport
        • Covered through special studies (soft $)
        • Peripheral benefit of climate/stratospheric ozone
          • NOAA/NASA Satellite programs
          • NOAA CMDL (aircraft, ships, buoys, sondes)
      • National Monitoring strategy (NCore)
        • Multiple pollutant co-location emphasis
          • Drive air program policy
        • Emphasis shift from compliance toward science
        • Addition of trace (low level ) gas measurements (CO, NOy, SO2, NH3)
        • Larger integration with satellite and vertical profiling systems
    • NCore Measurements Level 2: ~ 75 Multi-pollutant (MP) Sites,“Core Species” Plus Leveraging From PAMS, Speciation Program, Air Toxics Level 1 . 3-10 Master Sites Comprehensive Measurements, Advance Methods Serving Science and Technology Transfer Needs Level 3 : Minimum Single Pollutant Sites (e.g.> 500 sites each for O3 and PM2.5 and related spatial Mapping Support L1 Minimum “Core” Level 2 Measurements Continuous NO,NOy,SO2,CO, PM2.5, PM10/PMc,O 3, Meteorology (T,RH,WS,WD) ; Integrated PM2.5 FRM, HNO3, NH3, L2 Level 3
    • Observational Systems: Focus?
      • Design around major assessment tools
        • Air quality modeling platforms
          • GEOS-chem, MOZART, CMAQ,….more
        • Satellite systems
        • Existing routine surface and aircraft programs
      • Emphasize
        • Model evaluation
        • Linkage of remote and land based systems
        • Integration of data information systems
    • Considerations [LRTAP observations guidance]
      • Emphasis on limited set of key parameters
        • [model evaluation, source apportionment, emissions perspective]
        • Gases (CO, NOy, NO2?, SO2, HCHO?, O3, Hg?, CH4,VOCi?)
        • aerosol components (C (EC, OC), S, N), mass/scattering
        • Meteorological?
      • Key locations, inflow and outflow perspective
      • Standardization/QA
        • Reference material, or method (aerosols)
          • E.g.,GAW Aerosol Speciation Programme, GASP
      • Data base, IT standards?
        • Hemispherical data unification center?
        • Practical LRTAP task?
      • Organizational frameworks
        • Build on IGACO-EMEP efforts
      • Use guidance to influence participating nations
    • Goal: Advance air quality model-observation complex to level of meteorological FDDA systems NCORE Intensive Field studies
    • GEOSS Eco-informatic Test beds Accountability/ indicators SIPs, nat. rules designations PHASE PM research Risk/exposure assessments AQ forecasting EPA NOAA NASA NPS USDA DOE Private Sector States/Tribes/RPO’s Interstate orgs.
