Project Background • The source-receptor relationship of particulate matter can be estimated by a number of empirical observation-based techniques. Some techniques are based chemical fingerprinting others on meteorological transport techniques. • A particularly attractive source-attribution technique, Paired Aerosol / Trajectory Analysis developed by Poirot and Wishinski. It combines the chemical and transport techniques by: • Establishing the major aerosol types at a specific receptor location and time (PMF and UNMIX) • Estimating the geographic transport regions for each aerosol type (Residence Time Analysis)

Coutant and ATAD trajectories from K. Gebhart High Secondary Coal contribution (yellow-red) originates from Upper Ohio River region Low Secondary Coal values (green-blue) occur during transport from Quebec High Biomass Smoke is transported from the N-NW direction Low Biomass Smoke occurs during transport from Quebec and the Ohio RV Region High Residual Oil aerosol type is transported from the East Coast Megalopolis Low Residual Oil occurs during transport from Quebec Project Goal: Develop an interactive data query and analysis tool for the paired chemical/trajectory analysis

Typical Source Profiles Prepared by Battelle and Sonoma Tech. Inc. Data Input: PMF/UNMIX Source Profiles and Residence Time Residence Time (calculated as “hours per 80 x 80 km grid cell”) at each 16 site and receptor day, were calculated by P. Wishinski, VT DEC The ResTime calculations are based on daily ATAD trajectories provided K. Gebhart, CIRA. Source attribution results (PMF and UNMIX) for 16 receptor sites between Illinois and New England using IMPROVE and CastNet data have been completed by a previous project. The results of the Battelle/Sonoma PMF and UNMIX modeling are source profile time series for each location

Project Objectives • Implement a relational database that incorporates both the PMF/UNMIX results and gridded trajectory data. • Develop specific SQL filtering and aggregation queries for • aggregated trajectory data based on chemical specifications • aggregated chemical data based on geographic specifications • Develop a graphic interface for user input (query) and for data output as rendered images or as exportable numeric data. • Transfer the resulting database to a designated SQL server and provide instructions for the addition of chemical and trajectory data.

PMF/UNMIX Data ATAD Residence Time Relational Database • PMF and UNMIX data transfer to SQL • The PMF and UNMIX results were provided to us as Excel spreadsheet. • The metadata for the PMF and UNMIX were obtained verbally from R. Poirot. • The spreadsheet data were reformatted and imported in the SQL server two tables (ChemFactTable and LocTable) • Residence Time data transfer to SQL • The residence time data were provided by P. Wishinski on CDROM including full metadata documentation • The data were imported into two SQL tables (ResTimeFactTable and LocTable) CAPITA SQL Database

Database Structure The dTrajResTime and dSourceApptables share the site_code and date keys thereby allowing paired queries to the SQL database.

SQL Queries SELECT Lat as lat, Lon as lon, Loc_Code as loc_code, SUM(ResTime) AS [VALUE] FROM dTrajResTime WHERE ([Date] IN (SELECT datetime FROM dSourceApp WHERE (Loc_Code = 'loc_code') sql_filter_clause)) GROUP BY GridCode, Lat, Lon, Loc_Code ORDER BY Lon ASC Settings that are unique to a specific query are designated by red text
