11. Study of Air Quality Impacts Resulting from Prescribed Burning on Military Facilities Objectives and Outlook
In this initial pilot study, establish understanding of the direct and indirect impact of current burn practices on sub-regional AQ.
Lay foundation for more comprehensive and better focused Phase II Study to optimize burn practices toward minimum AQ impact.
Create results for the benefit of LMBs on other mil installations in the SE-US and beyond.
Learn lessons that help create and implement new revised land management strategies for the benefit of other agencies and institutions that face often times devastating wild fires in other parts of the Nation.

12. Impacts on local to global scales
In the continental U.S. prescribed burns and forest fires contribute ~37 % to the total direct fine PM emissions of ~1 Mio t per year*

Difficulties
Are at the mercy of met conditions and (therefore) have to be prepared (flexible).
Sample media collection and delivery time consuming.

18. Preliminary PCM Results, cont’ed
Progressively increasing
fine PM mass
and increasing
organics fraction

19. More Preliminary Results: March’03
Increased fine PM mass and organics fraction correlate with increased temperature, solar radiation, and O3, indicating increased oxidizing potential, hence formation of SOA

20. Still To Do Collect more samples as progressing into summer
Analyze VOC samples
Analyze POC High-Volume samples
QA/QC all met, gas and PM data
Do source apportionment for select samples
Integrate ECMI met data from Ft Benning
Merge all AQ data with fuel data
Evaluate fuel-type – AQ relationship
Prepare data for model integration
Develop strategy for phase II
