| description | Landscape fires produce smoke containing a very wide variety of chemical
species, both gases and aerosols. For larger, more intense fires that produce
the greatest amounts of emissions per unit time, the smoke tends initially to
be transported vertically or semi-vertically close by the source region,
driven by the intense heat and convective energy released by the burning
vegetation. The column of hot smoke rapidly entrains cooler ambient air,
forming a rising plume within which the fire emissions are transported. The
characteristics of this plume, and in particular the height to which it rises
before releasing the majority of the smoke burden into the wider atmosphere,
are important in terms of how the fire emissions are ultimately transported,
since for example winds at different altitudes may be quite different. This
difference in atmospheric transport then may also affect the longevity,
chemical conversion, and fate of the plumes chemical constituents, with for
example very high plume injection heights being associated with extreme
long-range atmospheric transport. Here we review how such landscape-scale
fire smoke plume injection heights are represented in larger-scale
atmospheric transport models aiming to represent the impacts of wildfire
emissions on component of the Earth system. In particular we detail (i)
satellite Earth observation data sets capable of being used to remotely assess
wildfire plume height distributions and (ii) the driving characteristics of
the causal fires. We also discuss both the physical mechanisms and dynamics
taking place in fire plumes and investigate the efficiency and limitations
of currently available injection height parameterizations. Finally, we
conclude by suggesting some future parameterization developments and ideas on
Earth observation data selection that may be relevant to the instigation of enhanced
methodologies aimed at injection height representation. |
