Tool Development

Project Officer, Serpil Kayin, MARAMA
Project Period: September 2002 – July 2003
Progress Report: Dec 2002
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)

High Secondary Coal contribution (yellow- High Biomass Smoke is transported from the
red) originates from Upper Ohio River region N-NW direction
High Residual Oil aerosol type is transported
from the East Coast Megalopolis
Low Secondary Coal values (green-blue)
occur during transport from Quebec
Low Residual Oil occurs during transport
from Quebec
Low Biomass Smoke occurs during transport
from Quebec and the Ohio RV Region
Project Goal:
Develop an interactive data query and analysis tool for the above paired chemical/trajectory analysis
Data Input: PMF/UNMIX Source Profiles and Residence Time
Prepared by
Typical Source Profiles
Battelle and Sonoma Tech. Inc.
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
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.
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 renderd
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.
Deliverable 1:
•
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
–
–
•
Relational database
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)
