Proposal Outline: Extensions to the VIEWS System: Analysis Tools and Auxiliary Data R. Husar, CAPITA March, 2003 Presentation and Analysis Tools CATT for VIEWS$30k Gridder/Contourer$15k Dynamic maps in VIEWS$30k Server Hardware, Software, Install.$10K Auxiliary Data (See R. Poirot PPT, Dallas Inter - RPO Meeting) ASOS-Current Visibility UVB Network
Trajectory Aggregation Tool for VIEWS 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 ‘on the fly’ trajectory aggregation and use of VIEWS chemical data to set the aerosol conditions. Budget: $30k Implementation and Status: The CATT toll is now in beta testing by the MANEVU/MRPO group. This extension to CATT has been an option on the contract but funds were not available. The technologies of ‘on the fly’ trajectory aggregation and the VIEWS link have been tested for feasibility. R. Husar will lead this effort in close cooperation with B. Schichtel of CIRA/VIEWS.
Extending CATT to VIEWS Current MANEVU/MRPO Project Proposed Extension to VIEWS ‘On the fly trajectory aggregation for 150+ VIEWS sites 16 sites 180+ sites over the entire US 100+ ‘species’ 15 ‘species’
CATT Tool Implementation The beta version of CATT is available now for testing. available The tool displays the incremental transport probability for specified query conditions Combined Aerosol Trajectory Tool - CATT Query Conditions
Ad-hoc aggregation with VIEWS data The feasibility of ad-hog trajectory aggregation has been tested with success The combination with VIEWS chemical data is also practical
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.
Spatial Interpolation and Rendering Spatial Interpolation Settings Interpolate PM25 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 PM25 Conc. Grid PM25 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.
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
