This ratio can be used to determine if the nitrogen be used to determine if the nitrogen oxide plume is recent or aged. Ratios oxide plume is recent or aged. Ratios close to 1 imply fresh emissions; ratios close to 1 imply fresh emissions; ratios less than 1 imply increasing age with less than 1 imply increasing age with lower value.lower value.

Dynamic Contour MapsDynamic Contour Maps

A single contour map combining networks would enhance the understanding of sulfate across the country by including both rural and urban areas, and significantly increasing the site density.

Red dots indicate that all 15-minute average wind directions for that hour came from the same direction (petal) on a 16-point wind rose.

Sparklines are scaled to the maximum wind speed for the entire period.
