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

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

3 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

4 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.

5 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

6 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

7 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
