Special Issue Information
Dear Colleagues,
Atmospheric aerosols of mineralogical origin, i.e., desert dust, volcanic dust and volcanic ash, are among the most abundant particles in the atmosphere. The environmental impacts of dust/ash are manifold; they influence the Earth’s climate directly by scattering and absorbing solar radiation, and indirectly by influencing cloud formation and critical atmospheric species lifetime. Once emitted into the atmosphere, dust/ash particles can uptake or scavenge atmospheric trace gases (i.e., radicals, inorganic and organic species) and thus impact their atmospheric budget and the photochemical cycles occurring in the atmosphere. In addition, these heterogeneous interactions/reactions lead to the ageing of the dust particles and can modify the optical and hygroscopic properties of the particles and thus they directly impact the climate.
The scope of this Special Issue is broad and welcomes lab, field and modeling studies related to the impact of mineral dust, volcanic dust or volcanic ash particles on the chemistry of the atmosphere, the air-quality and climate. In particular, this Special Issue welcomes comprehensive research studies or review papers aiming to further our understanding on issues related to:
- The uptake/reaction of (i) radical species, (ii) volatile trace gases and (iii) semi/low volatile species (e.g., SOA) on the surface of dusts/ash particles;
- The photoenhanced or photocatalytic degradation of trace gases on the surface of dust/ash particles and proxies;
- The hygroscopic properties and ice nucleation activity of dust/ash particles and proxies;
- Dust events and their impact evaluation on the atmospheric budget of trace gases and air quality;
- The impact of volcanic ash on the atmospheric budget of trace gases and air quality;
- The impact of inorganic/organic ageing on the hygroscopic and optical properties of mineral dust/ash particles (research highly recommended).

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. Minerals 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.
