2. Translation Operations Gridding – Point-to-grind extrapolation –Standard 1/r2; declustering; Krieging (independent of rendering) ArcView Import of Grids –HDF-to-Arcview Raster translator (have it) Map Rendering –Arcview Spatial Analyst add-on

3. EPA Emission Densities No Canadian data yet

4. 1996 U.S. Total SO 2 Emission Density Darkest areas where the coal fired power plants are?

5. 1996 U.S. Total VOC Emission Density Recall – Main contributions from Industrial Processes and Transportation

6. 1996 U.S. Total NOx Emission Density Automobiles and Other Combustion Processes

7. 1996 U.S. Total PM-10 Emission Density More central distribution Non-Fugitive and Fugitive Sources included, but database incomplete

8. 1996 U.S. Total PM-2.5 Emission Density Similar distribution to PM-10 (also incomplete data) PM-2.5 best indicator for adverse health effects

9. PM Concentrations Complete Canadian data are available form B Vet Canadian data will be added shortly Issues of contour extrapolation

10. Annual PM2.5 Concentration Estimates The map is based on AIRS PM2.5 data (as of January 01). The FRM data start in Jan 1999 and are of uneven length and spatial coverage The annual PM2.5 spatial show –PM2.5 Hot spots over the West (San Joaquin and South Coast Air Basins) –Remarkably regional distribution over the East. Urban-metropolitan areas are barely discernable

11. PM2.5 Seasonal Concentration Need to add Canada data As contour? As color-coded bar?

12. Annual PM Coarse Concentration Estimates The map is based on AIRS PM2.5 data (as of January 01). The FRM data start in Jan 1999 and are of uneven length and spatial coverage The annual PM2.5 spatial show –PM2.5 Hot spots over the West (San Joaquin and South Coast Air Basins) –Remarkably regional distribution over the East. Urban-metropolitan areas are barely discernable

13. Annual PM10 Concentration Estimates The map is based on AIRS PM2.5 data (as of January 01). The FRM data start in Jan 1999 and are of uneven length and spatial coverage The annual PM2.5 spatial show –PM2.5 Hot spots over the West (San Joaquin and South Coast Air Basins) –Remarkably regional distribution over the East. Urban-metropolitan areas are barely discernable

16. Features of Air Flow over North America North America is under the influence of Pacific, Arctic and Tropical air masses. Between 30 0- 50 0 the the strong westerlies and a more broken mountain barrier allows maximum eastward transit of Pacific air. This ‘jet’ of westerly flow penetrating NAM at mid-latitudes entrains and mixes with air from the Arctic and the tropics. This unique distribution of land, sea and mountains produces a highly variable weather: From one day to another, mild, sunny air from the Rocky Mountains may replace moist, warm, cloudy tropical air and then give way to cold Arctic air.

17. Seasonal Airstream Regions over N. America NAVAIR, 1966 January OctoberJuly April Streamlines are derived from monthly average surface winds. Airstream regions are separated from each other by convergence zones From October through January, the strong zonal winds bring Pacific air across the
