Nanoparticles are particles between 1 and 100 nm in diameter or at least in one dimension for tubes and fibers, as commonly defined. They have many unique properties compared to large particles or bulk materials due to a high fraction of molecules on the particle surface and a large surface area-to-volume ration. For instance, they can be chemically very reactive (as catalysts), transformed easily (sintering), or act as seeds for vapor condensation (new particle formation in the atmosphere). Nanoparticles have an important role in climate change, since they can grow to the size of cloud condensation nuclei and thus have a cool climate and, in contrast, absorb sun radiation warming climate as black carbon particles on snow. Moreover, nanoparticles have adverse health effects, since they can easily penetrate deep into the lungs during inhalation and thus cause unwanted reactions in the human body.
Nanoparticles in the atmosphere originate from various sources. In the urban atmosphere, nanoparticles are typically formed from different combustion processes during energy production and transport by petrol and diesel vehicles, and other industrial processes. In the rural areas, the nucleation and growth of new particles (i.e., new particle formation) is a very important source of nanoparticles. Nanoparticles can also escape to the atmosphere during the manufacture and use of engineered nanoparticles.
The characterization of nanoparticles is often very challenging, because the size or mass of the analyzed particles is below the detection limit of commonly used chemical analysis methods; furthermore, particle losses in sampling lines can be remarkable, or they can be transformed or destroyed during investigation by electron microcopy, for example. However, recently novel methods have been developed for nanoparticle analysis, e.g., mass spectrometers and particle size magnifiers.
The aim of this Special Issue is to gain insight into the current literature on nanoparticles in the atmosphere. Contributions from laboratory and field measurements and theoretical and modelling studies of nanoparticles from various atmospheric environments are welcome. Furthermore, recent studies on the development of nanoparticle characterization methods, as well as studies on nanoparticle formation mechanisms, are also anticipated. Finally, contributions focusing on the effects of nanoparticles on the Earth's climate and human health are very welcome.

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 papers will be 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 1800 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.
