Proposal to NARSTO: Incorporation of Canadian and Mexican PM data into NAM Spatio-Temporal Analysis Submitted to NARSTO Rudolf Husar May 2001

PM2.5 Networks over N. America The Canadian & US PM2.5 data will be reformatted for integration Compatible parameters (PM2.5, SO4…) extracted

Data Processing and QA Summary statistics calculated –Seasonal average –Annual average –Seasonal Percentiles (20, 50, 80, 90%) Compatibility of US & Canadian data evaluation (to some degree) –Comparison of co-located samples (few but available) –Average concentration comparison near boundary –Elimination of early 1999 US PM2.5 FRM data –Other tests, to be determined

Seasonal contour maps Canadian data to be added Seasonal and annual PM2.5 maps will be prepared In remote Canada, data will be shown as color coded bars.

New England: Fine Particle Mass Percentiles The same seasonal trend charts will be done for selected Canadian sites Shows both the average, seasonality and the episodicity of PM concentration Lye Brook MoosehornAcadia

Seasonal PM10 Mexico Mexico for 36 stations, 5 cities are available from Mexico Additional FRM PM10 data are in AIRS for El Paso, Mexicali and other boarder sites Seasonal pattern will be evaluated Guadalajara Monterrey Toluca Mexico City

New England: Seasonal Chemical Mass Balance The same seasonal chemical trend charts will be done for selected Canadian sites Shows the seasonal contribution of different species Lye Brook MoosehornAcadia Proctor Maple Ringwood
