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
