1. Descriptive Analysis Database Archive monitoring network locations, climate, emissions, wildfires, census, political, physical, and image databases Databases will help us build conceptual models and answer descriptive analysis questions by visualizing data (e.g. map emissions densities) Assist us in the general and detailed description of the meteorological setting of each site Over 90 GB of data archived at DRI

2. Causes of Haze IMPROVE Study Sites

3. Sources of Data Air quality networks (data archived from VIEWS) –IMPROVE and IMPROVE protocol sites –EPA Speciation Trends sites Other networks (no data archived) –State/local agency SLAMS/NAMS/PAMS sites PM 10, PM 2.5, SO 2, O 3, CO, NO x, met –CASTNet –Special studies (CRPAQS, CCOS, Mohave, Bravo, etc.)

4. IMPROVE, IMPROVE protocol and PM 2.5 sites

5. Sources of Data Existing meteorological data for 60 networks (data not archived) –State/local agency sites –NWS surface and upper air sites –RAWS –NWS Cooperative observers –Department of Defense Climate data (data archived) –Gridded monthly precipitation for US

6. Meteorological Networks

8. Sources of Data Emissions (data archived) –WRAP 1996 point, mobile, area sources –National Fire data 1970-1999 point locations –USDA fire locations from MODIS satellite 2001-2003 –BLM fire locations for Alaska –Carnegie Mellon ammonia inventory –2000 street, airport and railroad centerlines –Sources inferred from landuse/landcover data –Sources inferred from satellite imagery and aerial photos

9. WRAP 1996 Point Source Inventory

10. Emissions surrounding Saguaro Wildfires include those from 1988 to 1999

11. Wildfires surrounding the Gila Wilderness in 2000

12. Sources of Data Physical and land cover data (data archived) –USGS digital elevation data at 10m, 30m, 90m and 1 km resolutions –USGS STATSGO soils –Census Bureau water bodies, rivers, streams –Vegetation from various agencies –Satellite imagery (Landsat 5 imagery circa 1990 for all of US and recent MODIS for some areas)

13. Landuse surrounding Saguaro circa 1992

14. Visualizing the Tucson urban area Saguaro West Saguaro East Tucson N Landsat 5 image circa 1990 draped over 30 meter DEM

15. Sources of Data Political data –Census Bureau 2000 state, county, urban area, and zip codes boundaries –Census Bureau 2000 census blocks and tract boundaries and demographic data –Land ownership from various state agencies –State, federal and tribal land boundaries from various agencies

16. Site Questionnaire Site location and history (most of this is available via IMPROVE metadata) UTM or lat/long coordinate; accuracy of coordinate; how coordinate was collected Elevation of site When did the site start or stop? Changes in monitor/filter technique Is it collocated with a scene camera? Site photos Site operator(s) Distance to other class I areas Did the site move over the years?

17. Site Questionnaire Physical setting: terrain, land use and land cover Approximate slope surrounding site (percent) Aspect surrounding site (0-360 degrees, 0 = facing north, 90 = facing east) What is the dominant land cover surrounding the site? What is the dominant land use surrounding the site? Describe land ownership surrounding the site Tallest natural or man-made structures nearest to site (note exposure to surrounding terrain) Distance to land features such as bodies of water (from lakes to oceans), canyons, etc. (note elevations) Describe surrounding terrain features keeping the different landscape scales in mind

18. Site Questionnaire Sources (note distances, direction and activity levels) Roads within 1 km (paved, unpaved, parking lots) Structures within 1 km (residences/lodging, public and restricted access facilities) Towns, cities or settlements Industrial source areas and point sources Agricultural areas Seasonal anthropogenic sources Disturbed vacant land Distance to natural sources

19. Site Questionnaire Meteorology and Climatology Surrounding surface meteorological stations; name of network; what parameters are collected? Closest air quality station; name of network; what parameters are collected? Describe generally how wind flow patterns are modified by various land features at difference scales Describe diurnal differences in wind flows Describe seasonal differences in wind flows, meteorological events (note fogs, snow, rain) Could the site be influenced by inversions? Any historical field study data?
