WRAP Workshop on Monitoring & Data
for Regional Analysis
May 15, 2008
1. Summary of hourly data in pollutant rose – what directions do high hourly PM2.5 events come from and how often?2. Summary of daily PM2.5 vs. daily standard for same time period
1. Ozone timeline for July 2004 at an urban (top) and rural (bottom) site in Georgia.2. Timeline of the NOx/NOy ratio below the ozone trace. This ratio can be used to determine if the nitrogen oxide plume is recent or aged. Ratios close to 1 imply fresh emissions; ratios less than 1 imply increasing age with lower value.3. Note the differences between the urban and rural traces: - Higher urban O3 peaks; lower urban O3 at night - Older plume assumed at rural site based on NOx/NOy ratio
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.
2006 4th highest 8-hour averages at non-urban sites
Metric Selection for Data Bubbles
> 4th highest 8-hr average (select YR)
> No. of exceedances (select YRs)
> 3-yr avg. 4th highest 8-hr avg. (select YR)
> No. of violations (select YRs)
1. Select site to pull up ozone and associated data from multiple nearby networks. 2. Refine time period selection (next page) to review specific episodes.

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.
