  1. Mid Term ReviewOct 25, 2004 Shao-Meng Li ARQP

  2. Development of the AMS Development of a DMA calibration system Field study deployment Development of AMS IDEA software Attendance at the 5th AMS User Meeting Publications

  3. Development of a DMA calibration system • Development of a DMA calibration system • Prototype completed • Deployment in laboratory and in field • Laminar flow element problems • Packaging issues

  4. Development of the AMS IDEA software • First phase • Mass calculation completed • Capability to keep track of all variations in calculation conditions, fragmentation tables • Plotting capabilities for single and multiple graphs/plots • Data exporting to Excel and others • Second phase • Implementation of ToF data conversion • Optimization of data conversion schemes

  5. Field Study Deployment • SOLAS Pacific Ocean, Jul – Aug 02 • Egbert Training, Sep – Nov 02 • Egbert Nitrogen Study, Mar – Apr 03 • Lab Study, May – Jun 03 • Toronto Urban Study, Jul – Aug 03 • SOLAS Atlantic Ocean, Oct – Nov 03 • Lab Study, Nov – Dec 03 • Preparation for ICARTT, Jan – Jun 04 • ICARTT, Jun – Aug 04 • LFV Chicken Study, Sep 04 – present • Lab Study, Nov 04 – Jan 05 • LFV Chicken Study, Feb 05 • Whistler, Mar – Apr 05 • Prairie 2005, Apr – Aug 05

  6. AMS reconfiguration for aircraft deployment • AMS deployment on aircraft • Installation • Deployment during ICARTT • Recalibration of AMS at different inlet pressure and temperature

  7. AMS Laboratory Studies • AMS reconfiguration • Laboratory chamber studies on heterogeneous uptake of gases include: • Organic nitrates • carbonyls, alcohols, acids • others

  8. Publications • Liggio et al.: On carbonyl polymerization on aerosols, ES&T (accepted) • Liggio et al: Reactive uptake of organics on aerosols, JGR (in press) • Others….

  9. Significance of agricultural NH3 sources Ambient NH3 changes in response to chicken culls Ambient PM change in response to NH3 changes Emission factors and inventories from poultry industry

  10. Chicken Cull Area, May 04

  11. Passive NH3 sampler network

  12. Spatial NH3 Concentrations

  13. Temporal NH3 Concentrations

  14. Studies on NH3 emissions from poultry farms

  15. Barn study preliminary results

  16. Deployment of AMS and MOUDI during the “chicken” study • Two AMS’ were deployed sequentially at the Abbotsford Airport GVRD site (Aug – Sep and Sep Nov, 2004 • First data from early Aug indicate very low ammonium/nitrate/sulfate • AMS measurements and data collection continues unattended until early Nov 04 • MOUDI sampling on a 12 hour basis in Oct – Nov

  17. Pacific 2001 data analysis and interpretation

  18. First Special Issue • 14 papers in the 1st special issue • Papers appeared on web site, printed version expected in Nov 04 • 3 papers in other journals

  19. Second Special Issue • Papers submitted • Wang, Aklilu, Leithead, Cheng • Papers in preparation • Anlauf, Norman, McLaren, Sukloff • Need to have more papers from other PIs • Huang, Brook, Lu, others? • Summary paper • Vingarzan

  20. Pacific 2001 Data • Existing Data • 71% of expected data sets • Continuous submission of data
