Special Issue Information

Dear Colleagues,

Combustion processes are important sources of submicron aerosols. These aerosols may be directly emitted (e.g., black carbon or primary organic aerosol) or they may form in the atmosphere through photochemical reactions (e.g., sulfate or secondary organic aerosol). Even though some combustion sources have been studied for decades, our understanding of them is in nearly perpetual flux. For example, emissions standards for on-road motor vehicles have become more stringent, and wildfire occurrence and severity are projected to increase; both of these changes can have severe implications for ambient air quality and the global climate. Moreover, novel analytical tools (e.g., instrumentation, statistical techniques) are under continual development, so we now have the ability to collect and/or interpret data in ways that were simply unavailable in the past.

This Special Issue seeks original research articles and review articles encompassing the many different facets of combustion aerosols. Any combustion source will be considered, ranging from the “personal” scale (e.g., cookstove, e-cigarettes) to the urban scale (e.g., motor vehicles) to the regional/global scale (e.g., wildland fires) and all points in between (e.g., off-road engines, power plants, incinerators). We are interested in both laboratory and field measurements, as well as modeling studies ranging from box models to global chemistry–climate models. Topics of interest include, but are not limited to, the following:

  • Chemical, optical, and/or microphysical characterization of combustion aerosols;
  • Secondary aerosol formation and/or evolution of aerosol optical properties due to physicochemical processing of combustion emissions;
  • Phase partitioning of primary organic aerosols emitted from combustion sources;
  • Atmospheric transport of combustion-related aerosols;
  • Health and/or climate effects of combustion aerosols;
  • Impact of policy changes on future combustion aerosol emissions.

Source apportionment and remote sensing studies should have a strong connection to combustion aerosols for consideration; similarly, studies focusing on the development of instrumentation or computational tools should include an application to combustion aerosols. If in doubt, potential authors are encouraged to contact the guest editors with questions about the suitability of their research for the Special Issue prior to submission.

Controlled laboratory combustion experiments were conducted in the fire test room to mimic freshly emitted smoldering smoke of biomass burning in China. The biomass components were determined by ultimate analysis and proximate analysis before experiments. The particle number size distribution (PNSD) between 5 and 1000 nm of smoke was measured by a high sampling frequency size spectrometer. A cavity-enhanced aerosol albedometer with wavelength of 532 nm was used to measure scattering coefficients, extinction coefficients, and single scattering albedo (SSA) of smoldering smoke. The PNSDs of smoldering smoke from the burning of agricultural straw could be fitted with a bimodal lognormal distribution as modes around 10 nm (nucleation mode) and 60 nm (Aitken mode). The PNSDs of wood sawdust could be fitted with a trimodal lognormal distribution, while the two modes were in nucleation mode, and one was in Aitken mode. The bulk optical properties (scattering and extinction coefficients) of smoldering smoke had strong correlations with particle number concentrations of sizes bigger than 100 nm. The correlation between SSA and fixed carbon (FC) was strong (the correlation coefficient is 0.89), while the correlation between SSA and volatile matter (VM) or ash was weak. The relationship between SSA and N (or S) showed a positive correlation, while that of SSA and C showed a negative correlation. The relationship between SSA and VM/FC (or N) showed a strong linear relationship (r2 > 0.8). This paper could improve understanding of the relationship between the optical and particle size distribution properties of smoke from biomass burning and the components of biomass materials under similar combustion conditions.
