| Zusammenfassung |
| The last decade has seen tremendous advances in atmospheric aerosol particle
research that is often performed in the context of climate and global change
science. Biomass burning, one of the largest sources of accumulation mode
particles globally, has been closely studied for its radiative, geochemical,
and dynamic impacts. These studies have taken many forms including
laboratory burns, in situ experiments, remote sensing, and modeling. While the
differing perspectives of these studies have ultimately improved our
qualitative understanding of biomass-burning issues, the varied nature of
the work make inter-comparisons and resolutions of some specific issues
difficult. In short, the literature base has become a milieu of small pieces
of the biomass-burning puzzle. This manuscript, the second part of four,
examines the properties of biomass-burning particle emissions. Here we
review and discuss the literature concerning the measurement of smoke
particle size, chemistry, thermodynamic properties, and emission factors.
Where appropriate, critiques of measurement techniques are presented. We
show that very large differences in measured particle properties have
appeared in the literature, in particular with regards to particle carbon
budgets. We investigate emissions uncertainties using scale analyses, which
shows that while emission factors for grass and brush are relatively well
known, very large uncertainties still exist in emission factors of boreal,
temperate and some tropical forests. Based on an uncertainty analysis of the
community data set of biomass burning measurements, we present simplified
models for particle size and emission factors. We close this review paper
with a discussion of the community experimental data, point to lapses in the
data set, and prioritize future research topics. |
