Dear Colleagues,

High-latitude regions (HLRs) are the most remote but also the most vulnerable sites on Earth to current climate change. It has been suggested that mineral dust contributes to the amplification of climatic effects over there (the so-called ‘Polar amplification effect’) through the deposition of light-absorbing particulate on snow and ice. Mineral dust can also affect the radiative forcing in HLRs by scattering and absorbing solar and thermal radiation and by acting as condensation nuclei on clouds.

The effects of dust are driven by the nature and properties of its constituent particles which, in turn, are strictly dependent on sources. While local sources of dust are able to exert a fairly regular influence on the aerosol properties, the influence of long-range sources can change considerably over time depending on both the activation of the source regions (i.e., dust resuspension) and the atmospheric circulation path. Therefore, a detailed analysis of the soil sources, the emission rates, the particle characteristics, the long-range trasport routes, and the atmospheric processing of dust reaching the HLRs is the starting point to evaluate its current impact on those regions and, possibly, to predict its future effect on the global scenario of climate change.

This Special Issue aims to integrate and summarize contemporary insights and findings on the above topics. Both research articles and reviews that provide a cross-cutting view of the progress of research on the sources and properties of long-range transported dust affecting HLRs are welcome. We are particularly interested in original research papers dealing with the relationships between long-range soil sources and dust properties at receptor sites by field measurements, observational studies, laboratory experiments, and numerical models.

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.
