  1. Using GIS Technology for Emission Inventory and Air Quality Applications Prepared by: Tami H. Funk Lyle R. Chinkin Sonoma Technology, Inc. Petaluma, CA SCOS97-NARSTO DATA ANALYSIS CONFERENCE February 14, 2001 STI-2059

  2. Overview • Introduction to Geographic Information System (GIS) • Emission inventory-related GIS applications • Air quality-related GIS applications • Summary

  3. Introduction • GIS provides a method to display a large amount of data in a meaningful way. • Visualize patterns. • Integrate, manage, solve, and present information in an interpretive way. TABLE GRAPH GIS • Analyze spatial problems and make decisions. • Illustrate and enhance data quality assurance.

  4. Emission Inventory Applications (1 of 4) • Display and analyze emissions densities and spatial distribution. • Develop gridded surrogates for distributing county-wide emissions. • Verify and “ground truth” emissions sources using several sources of data. • Link interactive databases to geographic features.

  5. Emission Inventory Applications (2 of 4) Emissions from Consumer Products - Los Angeles Co.

  6. Emission Inventory Applications (3 of 4) Air Quality Site Characterization and Emissions Activity Databases

  7. Emission Inventory Applications (4 of 4)

  8. Exposure Applications (1 of 7) • Spatial analysis and display of air quality data • Verify locations of sources and receptors for modeling • Exposure analyses • Data quality assurance

  9. 1-hr Average Peak Ozone Concentrations Sacramento Region 0 - 60 ppb 61 - 79 ppb 80 - 99 ppb 100 - 110 ppb 111 - 124 ppb 125+ ppb Exposure Applications (2 of 7) Air Quality Data Mapping

  10. Exposure Applications (3 of 7)

  11. Exposure Applications (4 of 7) Air Quality Exposure Analysis

  12. Spatial distribution of person-days per year of exposures to 8-hr maximum outdoor ozone concentrations above 80 ppb in Houston, Texas, for 1993-1995 (Lurmann et. al., 1999). Exposure Applications (5 of 7) Number of Person-days Per Year Air Quality Exposure Analysis

  13. Exposure Applications (6 of 7) Data Quality Assurance

  14. Mapping Air Quality Sampling Flight Paths Exposure Applications (7 of 7)

  15. Summary • New and improved geographical data are rapidly becoming available with the widespread use of GIS technology. • GIS provides an easy way to QA, display, and analyze emissions and air quality data. • Geodatabases provide a way to link tabular data to geographical maps. • Many other potential applications.
