Recommendations to Task Force

1. 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

2. 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

3. L2 Level 3 NCore Measurements Level 1. 3-10 Master Sites Comprehensive Measurements, Advance Methods Serving Science and Technology Transfer Needs Level 2: ~ 75Multi-pollutant (MP) Sites,“Core Species” Plus Leveraging From PAMS, Speciation Program, Air Toxics L1 Level 3: Minimum Single Pollutant Sites (e.g.> 500 sites each for O3 and PM2.5 and related spatial Mapping Support Minimum “Core” Level 2 Measurements Continuous NO,NOy,SO2,CO, PM2.5, PM10/PMc,O3,Meteorology (T,RH,WS,WD); Integrated PM2.5 FRM, HNO3, NH3,

4. 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

5. 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

6. NCORE Intensive Field studies Goal: Advance air quality model-observation complex to level of meteorological FDDA systems
