CATT for VIEWS and other Aerosol Datasets
Background:
A combined aerosol trajectory aggregation tool, CATT, has been developed for easy aggregation and browsing of airmass histories associated with specific aerosol conditions. The CATT tool,
is now supported (MANEVU/MRPO) for 16 stations and for pre-calculated residence times.
Proposal:
We propose to extend the CATT tool by allowing the use of the entire VIEWS chemical database and other remotely accessible datasets to set the aerosol filter conditions.
Budget:
$20k
Implementation and Status:
The technologies or remotely accessing the VIEWS and other databases and performing chemical filtering queries to VIEWS has been tested for feasibility. The prototype CATT tool for 16 sites is now in beta testing by the MANEVU/MRPO group. This extension to CATT has was option on
the contract but funds were not available. R. Husar will lead this effort in close cooperation with B. Schichtel of CIRA/VIEWS.
Deliverables:
The main deliverable of this sub-project is a fully functioning CATT aerosol transport anlysis tool applicable to the entire VIEWS database as well as to other chemial/trajectory data pairs. It is
assumed that the companion Trajectory Aggregation Tool, TAT, will be developed under an EPA small grant.

Spatial Interpolation and Rendering Tool for VIEWS
Background:
A tool for transforming point measurement data to a continuous surface would aid the analysis of VIEWS data and their comparison with other data from monitoring, emissions, satellite as well as with model results
Proposal:
We propose to incorporate spatial interpolation and rendering facilities into the Dvoy data access and browsing system. The Gridder/Contourer tool will be applicable to the spatial datasets in VIEWS as well
as from other monitoring networks.
Budget:
$15k
Implementation and Status:
The gridder/contourer technology has been developed at CAPITA over the past 15 years. Stefan Falke, who did his PhD dissertation on spatial interpolation will lead the effort.
Deliverables:
The deliverable of this sub-task is is a web-based Gridder/Contourer that can access VIEWS to retrieve spatial point measurement data and perform advances spatial interpolations. The outputs from the
Gridder/Contoures will be suitable for import into GIS and other processing/rendering software.

Spatial Interpolation Settings
InterpolatePM25 Conc.
The spatial interpolation operator transforms a data table to a gridded map using nearby measurement data.
The gridding and contouring of the selected data is done ‘on the fly’ by the user
Point Rendering

Contour Rendering
Gridding: Accounting for Data Density
The advanced spatial interpolation algorithm accounts for the variations in point data density inherent in air quality monitoring networks.
The resulting interpolated estimates are more representative of the urban and rural differences in air pollutant concentrations.
Low Point Data Density
High Point Data Density
Rendering: Rectangular, Contour, Lines
Rectangular Grid Cells Contoured Grid Cells Contoured Grid Lines
A flexible display rendering of gridded data will be implemented to accommodate different applications.
The flexibility enables clearer presentation and easier comparison with other data.
Dynamic Maps for VIEWS
Background:
The Visibility Information Exchange Web System, VIEWS is an online exchange of visibility data, research, and ideas to support the Regional Haze Rule. The VIEWS system also provides
spatio-temporal summaries of key haze parameters.
Proposal:
We propose to enhance the current image-based VIEWS spatial data delivery system by a dynamic mapping module for flexible presentation of spatial data.
Budget:
$30k
Implementation and Status:
The Voyager data browser has a flexible mapping module that can be incorporated into the VIEWS delivery system. For the past year, B. Schichtel of CIRA/VIEWS and R. Husar/CAPITA have
been planning the mapping module transfer but the resources were not available.
Deliverables:
A web-based program to access VIEWS data, dynamically render the data as points or contours, and overlay the VIEWS data on geographic and temporal data layers for other providers.
VIEWS and ‘Voyager’ Data Presentation
• VIEWS data summaries are mostly pre-calculated
• The spatial images are pre-rendered and saved
• The data layers, zoom, labels etc are set
• Voyager accesses most data from the database• The spatial images are generated at use time• Data layers, zoom, labels etc are set by user
