New emission factors for Australian vegetation fires measured using open-path Fourier transform infrared spectroscopy – Part 1: Methods and Australian temperate forest fires
Biomass burning releases trace gases and aerosol particles that significantly affect the composition and chemistry of the atmosphere.

description |
Biomass burning releases trace gases and aerosol particles that
significantly affect the composition and chemistry of the atmosphere.
Australia contributes approximately 8% of gross global carbon
emissions from biomass burning, yet there are few previous measurements of
emissions from Australian forest fires available in the literature. This
paper describes the results of field measurements of trace gases emitted
during hazard reduction burns in Australian temperate forests using
open-path Fourier transform infrared spectroscopy. In a companion paper,
similar techniques are used to characterise the emissions from hazard
reduction burns in the savanna regions of the Northern Territory. Details of
the experimental methods are explained, including both the measurement
set-up and the analysis techniques employed. The advantages and
disadvantages of different ways to estimate whole-fire emission factors are
discussed and a measurement uncertainty budget is developed.
<br><br>
Emission factors for Australian temperate forest fires are measured locally
for the first time for many trace gases. Where ecosystem-relevant data are
required, we recommend the following emission factors for Australian
temperate forest fires (in grams of gas emitted per kilogram of dry fuel
burned) which are our mean measured values: 1620 ± 160 g kg<sup>−1</sup> of
carbon dioxide; 120 ± 20 g kg<sup>−1</sup> of carbon monoxide; 3.6 ± 1.1 g kg<sup>−1</sup>
of methane; 1.3 ± 0.3 g kg<sup>−1</sup> of ethylene; 1.7 ± 0.4 g kg<sup>−1</sup> of formaldehyde; 2.4 ± 1.2 g kg<sup>−1</sup> of
methanol; 3.8 ± 1.3 g kg<sup>−1</sup> of acetic acid; 0.4 ± 0.2 g kg<sup>−1</sup> of formic acid; 1.6 ± 0.6 g kg<sup>−1</sup> of
ammonia; 0.15 ± 0.09 g kg<sup>−1</sup> of nitrous oxide and 0.5 ± 0.2 g kg<sup>−1</sup> of
ethane. |
