Special Issue Information
Dear Colleagues,
Wildfires are increasing in intensity and severity in many places and the resulting biomass burning (BB)-derived aerosol directly influences the Earth’s climate via the attenuation of solar and terrestrial radiation. It is well known that BB-derived aerosols contribute to climate forcing, but in most cases, the measurements of aerosol optical properties are either limited to a specific source region or confined to a limited wavelength range. Internally mixed particles can have very different optical properties from externally mixed particles. A major uncertainty in direct aerosol radiative forcing is the single-scattering albedo (SSA), which is the fraction of radiation that the particle scatters rather than absorbs. A small error in estimating SSA can change the sign of aerosol radiative forcing. The SSA that depends on the scattering and absorption properties of BB-derived aerosol also depends on several factors, including burning conditions, particle size and density, chemical composition, aging, and meteorological conditions. BB influences atmospheric composition at all latitudes. It is a major source of aerosol that can substantially degrade the near-source air quality and alter radiative forcing on a regional and continental scale. BB is one of the largest sources of atmospheric organic (OC) and black carbon (BC) aerosol, where the latter is a substantial and well-established contributor to absorbing aerosols in the atmosphere.
We invite researchers studying the chemical and optical properties of biomass-burning aerosols and their impact on health, climate, and air quality to contribute to this edition.

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.
