Comprehensive emission measurements from prescribed burning in Florida: field and laboratory, aerial and ground
Aurell, J., A. Holder, AND B. Gullett. Comprehensive emission measurements from prescribed burning in Florida: field and laboratory, aerial and ground. Interntional Smoke Symposium, College Park, MD, October 24, 2013.
This presentation complements a STiCS-approved abstract (below) and will present the sampling methodology and some illustrative results from past prescribed fire sampling. The talk will highlight the methods used in past field efforts and some of the data. The majority of the data, in different form, have been released in previous journal publication.
Simultaneous aerial- and ground-based emission sampling was conducted during prescribed burns at Eglin Air Force Base in November 2012 on a short grass/shrub field and a pine forest. Cumulative emission samples for volatile organic compounds, elemental carbon, organic carbon, chlorinated dioxins and furans, and PM2.5 and continuous samples for black carbon, particle size, and CO2 were taken. Aerial instruments were lofted using a 5 m diameter, helium-filled aerostat that was maneuvered with two remotely-controlled tethers mounted on all-terrain vehicles. A parallel set of instruments on the ground made simultaneous measurements, allowing for a comparison of ground level versus elevated measurements. Ground instruments were supplemented by additional measurements of polycyclic aromatic hydrocarbons and particle aerosol absorption and light scattering. Raw biomass was also gathered on site and tested in a laboratory combustion facility using the same array of instruments. This work compares emissions derived from aerial and ground sampling as well as field and laboratory results.
