Development of the AMS Development of a DMA calibration system Development of a DMA calibration system Field study deployment Field study deployment Development of AMS IDEA software Development of AMS IDEA software Attendance at the 5 th AMS User Meeting Attendance at the 5 th AMS User Meeting Publications Publications
Development of a DMA calibration system –Prototype completed –Deployment in laboratory and in field –Laminar flow element problems –Packaging issues
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

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
First Special Issue 14 papers in the 1 st special issue Papers appeared on web site, printed version expected in Nov 04 3 papers in other journals
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
Pacific 2001 Data Existing Data 71% of expected data sets Continuous submission of data
