  2. Daily measurements of PM2.5 & PM10 composition Particle number size distributions Hourly measurements by AMS and wet chemistry techniques First Intensive Measurement Periods Jun 2007 & Jan 2008

  3. Cabauw (NL11) Auchencorth (GB40) Mace Head (IE31) Harwell (GB36) Ispra (IT04) Network of 2006/07 Real-time Measurements

  4. Aerodyne Aerosol Mass Spectrometer (AMS) Particle Particle Beam Aerodynamic Sizing Composition Generation Quadrupole Mass Spectrometer Chopper Thermal Vaporization & Electron Impact Ionization TOF Region Aerodynamic Lens (2 Torr) Turbo Pump Turbo Pump Turbo Pump Particle Inlet (1 atm) 100% transmission (30-600 nm), aerodynamic sizing, linear mass signal.

  5. The MARGA/GRAEGOR

  6. Comparison AMS vs. MARGA

  7. Measured Time-Series: June 2006

  8. Nitrate

  9. Sulfate

  10. Ammonium

  11. HNO3 & HCl

  12. Averaged Diurnal Cycles January 2007 June 2006

  13. Investigate at transport across Europe Contrast local controls (e.g. NO3-) Integrate with daily measurements (at more sites) Provide dataset for validation of atmospheric transport models Data usage

  14. Coarse vs. Fine Mode NO3- • Harwell (June 2006): 49% fine : 51 % coarse • Harwell (Jan 2007): 61% fine : 39 % coarse

  15. Comparison of European EMEP model with EMEP intensive measurements (Svetlana Tsyro et al., 2007) Melpitz, Germany DE44 Birkenes, Norway NO01

  16. EMEP4UK:Application of EMEP model to the UK at 5 km x 5 kmNH4+ on 02/01/2003 12:00 GMT 3 ppb NH4 0

  17. Initial comparison of EMEP4UK with Auchencorth January 2007 NHy [mg m-3] for 6-Jan-2007

  18. Increase European Coverage of daily and hourly aerosol measurements (inc. S. & E. Europe) Integrate with other network measurements (EUCAARI, EUSAAR) Add more gas-phase measurements (NH3 & HNO3) EC/OC measurements (awaiting EUSAAR recommendations) Quantify water content Improve estimates of OC/OM ratio Vertical gradients (link to Lidar network) Improve estimates of OC/OM ratio Compile European Aerosol Climatology based on Aerosol Mass Spectrometry (Synchronized) database for OM analysis (HOA/OOA-I/OOA-II) Objectives for Next Campaigns

  19. Map of Potential Sites
