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

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

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
