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

Causes of Haze IMPROVE Study Sites

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

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)

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

Site QuestionnaireSite 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?

Site QuestionnairePhysical 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

Site QuestionnaireSources (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

Site QuestionnaireMeteorology 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?

Draft Descriptive Database

Meteorological Networks

Next task: Add capability to perform queries to the database using a search radius

Meteorological Conditions

Database contains specific events and affect extinction

Linking conditionsThe database can assist in the identification of meteorological conditions based on a physical attribute

Draft Causes of Haze Website

• Modeled after

VIEWS website

• Developed

and managed

at DRI

• Possible URL

http://coha.dri.edu

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

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)
