Special Issue Information

Dear Colleagues,

Biomass Burning (BB) is a global phenomenon and the contribution of BB aerosols in the atmosphere is the highest in the tropics. BB is a major source of aerosols and it can substantially degrade air quality near their sources, but these pollutants are also subject to long range transport. BB influences atmospheric composition at all latitudes. BB is one of the largest sources of organic aerosols black carbon (BC), or absorbing aerosols, in the atmosphere. It is well known that BB aerosols contribute to climate forcing, but much is still unknown about the extent of this forcing, owing to the high level of uncertainty regarding BB aerosol optical properties. The impact of biomass smoke on health is significant and it is a global health disparity issue. Biomass burning generates hundreds of incomplete combustion products in the form of gases and aerosols. Epidemiological studies associate household air pollution with lung diseases, including chronic obstructive pulmonary disease, lung cancer, and respiratory infections. The focus of this Special Issue is to explore the various impacts of biomass burning including severe weather, climate, air quality and health. Manuscripts focused on laboratory studies, modeling and field studies to understand and quantify BB impacts in all regions and especially in developing countries are welcome.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Atmosphere is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Particle size distribution in biomass smoke was observed for different burning phases, including flaming and smouldering, during the combustion of nine common Australian vegetation representatives. Smoke particles generated during the smouldering phase of combustions were found to be coarser as compared to flaming aerosols for all hard species. In contrast, for leafy species, this trend was inversed. In addition, the combustion process was investigated over the entire duration of burning by acquiring data with one second time resolution for all nine species. Particles were separately characterised in two categories: fine particles with dominating diffusion properties measurable with diffusion-based instruments (Dp < 200 nm), and coarse particles with dominating inertia (Dp > 200 nm). It was found that fine particles contribute to more than 90 percent of the total fresh smoke particles for all investigated species. Full article
