Presentation Transcript

  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 120 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 • PM10, PM2.5, SO2, O3, CO, NOx, met • CASTNet • Special studies (CRPAQS, CCOS, Mohave, Bravo, etc.)

  4. IMPROVE, IMPROVE protocol and PM2.5 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

  7. Annual Precipitation around Grand Canyon National Park

  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 • Canadian wildfires 1959-1999 • 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 • Limited SSURGO soil data • 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 East Tucson N Saguaro West 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 2 km (paved, unpaved, parking lots) • Structures within 2 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?

  20. Draft Descriptive Database

  21. Meteorological Networks Next task: Add capability to perform queries to the database using a search radius

  22. Meteorological Conditions Database contains specific events and affect extinction

  23. Linking conditions The database can assist in the identification of meteorological conditions based on a physical attribute

  24. Draft Causes of Haze Website • Modeled after VIEWS website • Developed and managed at DRI • Possible URL http://coha.dri.edu

  25. Test sites • Hawaii (Volcanic NP) • Denali NP • San Gorgonio WA • Upper Buffalo WA • Saguaro NP (both sites) • Big Bend NP • Mount Ranier NP • Grand Canyon (all sites) • Boundary Waters WA

  26. Next Steps • Populate descriptive analysis database from existing data sources • Populate web site with test site • Publish draft web site on DRI web server • Incorporate new databases as they are made available (e.g. WRAP In/Near Emissions)
