  1. The National Atmospheric Deposition Program (NADP) Chris Lehmann & Mark Rhodes Illinois State Water Survey Sotiria Koloutsou-Vakakis Dept. of Civil and Environmental Engineering

  2. Who Are We? Chris Lehmann, Director, Central Analytical Laboratory for the NADP Mark Rhodes, Quality Assurance Manager, NADP Sotiria Koloutsou-Vakakis, Research Scientist, Dept. Civil & Environmental Engineering

  3. NADP Overview • Nationwide network of precipitation (rain & snow) and air quality monitoring sites • ~370 stations in 3 networks • 1 analytical laboratory, here on campus • 33+ year history • 357,740 samples from longest running network • All data available via the Internet at http://nadp.isws.illinois.edu

  5. Why are we here? We have lots of data and we need your help to interpret it!

  6. Our Questions (I) • Triplicate passive-type air samplers are deployed at selected sites for quality assurance. How well do the values agree, and is there a trend in agreement over time? Might triplicate variability correlate with other variables (temperature, wind speed, sampler reuse, etc.)?

  7. Our Questions (II) • We have estimates of air pollutant emissions, which are expressed on a county-level or grid basis. How can we correlate this spatial-scale data with our air quality point measurements?

  8. Our Questions (III) • How should we correlate estimated ammonia emissions (on a spatial scale), with other independent variables at similar (or differing) spatial resolutions. Such variables include land use, soil types, wind speed, and temperature.

  38. Back to our Questions… • Triplicate passive-type air samplers are deployed at selected sites for quality assurance. How well do the values agree, and is there a trend in agreement over time? Might triplicate variability correlate with other variables (temperature, wind speed, sampler reuse, etc.)?

  39. Our Questions… • We have estimates of air pollutant emissions, which are expressed on a county-level or grid basis. How can we spatially correlate this spatial-scale data with our air quality point measurements?

  40. Our Questions (III) • How should we correlate estimated ammonia emissions (on a spatial scale), with other independent variables at similar (or differing) spatial resolutions. Such variables include land use, soil types, wind speed, and temperature.
