Austin, TX ; October 14-17, 2003
Pattern of Fires over N. AmericaThe number of ATSR satellite-observed fires
peaks in warm seasonFire onset and smoke amount is unpredictable
Fire Pixel Count:

North America
Scientific Challenge: Description of smoke
• Gaseous concentration: g (X, Y, Z, T)
• Aerosol concentration: a (X, Y, Z, T, D, C, F, M)
• The ‘aerosol dimensions’ size D, composition C, shape F, and mixing M determine the impact on health, and welfare.
Dimension Abbr. Data SourcesSpatial dimensions X, Y Satellites, dense networks
Height Z Lidar, soundings
Time T Continuous monitoring
Particle size D Size-segregated sampling
Particle Composition C Speciated analysis
Particle Shape/Form F Microscopy
Ext/Internal Mixture M Microscopy
Particulate matter, incl. smoke is complex because of its multi-dimensionality
It takes at leas 8 independent dimensions to describe the PM concentration pattern
Technical Challenge: Characterization
• PM characterization requires many different instruments and analysis tools.
• Each sensor/network covers only a fraction of the 8-D PM data space.
• Most of the 8D PM pattern is extrapolated from sparse measured data.
Satellite-Integral
• Satellites, integrate over height H, size D, composition C, shape, and mixture dimensions; these data need de-convolution of the integral measures.
Smoke types: blue, yellow, white
Smoke from major fires comes in different colors, e.g. blue, yellow.
The chemical, physical and optical characteristics of smokes are not known
Can the reflectance color be used to classify smokes?
Can column AOT be retrieved for optically thick smoke? Multiple scattering, absorption?

Smoke Plumes over the Southeast
• Satellite detection yields the origin and location is the shape of smoke plumes
R 0.68 m
G 0.55 m
B 0.41 m
0.41 m
0.87 m
• The influence of the smoke is to increase the reflectance ant short wavelength (0.4 m)
• At longer wavelength, the aerosol reflectance is insignificant.

ASOS Visibility Monitoring System (1200 Sites)
• The Automated Surface Observing System, ASOS; weather every minute.
• The forward scattering (30-500) visibility sensor has a range 17 ft to 30 miles.
• The synoptic visibility data are truncated (<1/4, 1/4,..10+ miles)
• For smoke and haze events (vis. < 10 mile) truncation not a problem

Current Air Quality Information ‘Ecosystem’ (Draft for Feedback)
AQ information includes emissions, ambient & satellite data and model outputs
The distributed data are produced and provided by agencies, mostly through portals
Providers have different access protocols, formats, and information usage conditions
This lack of interoperability causes the under-utilization of the rich data resources

Non-intrusive Linking & Mediation Data UsersData Providers
DataFed Description
DataFed VisionBetter air quality management and science through by effective use of relevant data
DataFed GoalsFacilitate the access and flow of atmospheric data from provider to usersSupport the development of user-driven data processing value chainsParticipate in specific application projects
Approach: Mediation Between Users and Data ProvidersDataFed assumes spontaneous, autonomous emergence of AQ data (a la Internet)Non-intrusively wraps datasets for access by web servicesWS-based mediators provide homogeneous data views e.g. geo-spatial, time...
End-user programming of data access and processing through WS composition (limited)
ApplicationsBuilding browsers and analysis tools for distributed monitoring data Serve as data gateway for user programs; web pages, GIS, science toolsDataFed is currently focused on the mediation of air quality data
Anatomy of a Wrapper Service: TOMS Satellite Image Data
• Given the URL template and the image description, the wrapper service can access the image for any day, any spatial subset using a HTTP URL or SOAP protocol:
• Wrapper classes are available for geo-spatial (incl. satellite) images, SQL servers, text files,etc. The mediator classes are implemented as web services for uniform data access, transformation and portrayal.
