1. MARAMA/NESCAUM/LADCO Project: MARAMA/NESCAUM/LADCO Project: Source Apportionment of Air Quality Monitoring Data: Paired Aerosol / Trajectory Database Analysis Tool Development R. Husar, K. Hoijarvi, J. Colson, S. Falke, CAPITA Project Officer, Serpil Kayin, MARAMA Project Period: September 2002 – July 2003 Progress Report: Dec 2002

2. 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)

3. Biomass Smoke Avg. Mass:2.4 ug/m3 (32%) Species:OC, EC, S, K Summer Maximum East Coast Residual Oil Avg. Mass:0.38 ug/m3 (5%) Species: OC, EC, S, Si, Ni, V Winter Maximum Secondary Coal Avg. Mass:3.2 ug/m3 (42%) Species: S, OC, EC, Na Summer Maximum Illustration of Paired Chemical and Trajectory Analysis, Lye Brook, VT Wishinski and Poirot (2002) Based on Positive Matrix Factorization, PMF results from B. 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 above paired chemical/trajectory analysis

4. 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. Prepared by Battelle and Sonoma Tech. Inc. The results of the Battelle/Sonoma PMF and UNMIX modeling are source profile time series for each location Typical Source Profiles 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.previous project

5. Project Deliverables 1.Implement a relational database that incorporates both the PMF/UNMIX results and for gridded trajectory data. 2.Develop specific SQL filtering and aggregation queries for aggregated trajectory data based on chemical conditions aggregated chemical data based on geographic conditions 3.Develop a graphic interface for user input (query) and for data output as rendered images or as exportable numeric data. 4.Transfer the resulting database to a designated SQL server and provide instructions for addition of chemical and trajectory data.

6. Deliverable 1: 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) Deliverable Status: Complete
