21. NAtChem CORE Data Analysis - Alert (An example of PCA with trajectories incorporated)

22. NAtChem CORE Data Analysis - CAMNet

23. NAtChem/CORE Database - Planned Work Analysis of Alert and CAMNet data in collaboration with CORE and CAMNet PIs inlcuding:  Statistical techniques to handle BDLs and data gaps (e.g. Kalman Filtering)  Methods to handle data sets with mixed temporal resolution  Positive Matrix Factorization with the incorporation of back trajectories

24. NAtChem/Pacific2001 Database - Work to Date QA and preparation of files for submission to the NARSTO Data Center –Cassier Tunnel: 29 of 57 –Slocal Park: 29 of 40 –Langley: 41 of 58 –Golden Ears: 13 of 15 –Sumas Mountain: 27 of 44 –Convair 580: 34 of 36 –CFS Cessna: 22 of 23 -------------------------------------------------- –TOTAL: 195 of 273 (71%) possible files

25. NAtChem/Pacific2001 Database The Quality Assurance Package Enhancements for DES files include: –20 new checks (date/time, metadata) –Time series plot file size dramatically reduced –Program code shared with NARSTO, NAtChem, CORE, EPA Supersites

26. NAtChem/Pacific2001 Database - Planned Work Delivery of final Pacific2001 data files to the NARSTO Data Center on October 31, 2004 –Requires further quality assurance applied to data –To date, data files from four Principal Investigators and the Cessna have been submitted

27. The NAtChem Database and Analysis Facility - Conclusions Web-based data and product downloads are now available and are being used by governments, universities and others The budget, schedule and analysis work are all on track The hiring of the NAtChem/PM scientist has been delayed
