Special Issue Information

Dear Colleagues,

Atmospheric gases and aerosols affect air quality and play an important role in the Earth’s climate system (IPCC, 2013 and 2018). Nowadays, although the uncertainty in the total direct aerosol effect is reduced, it is still substantial compared to uncertainties associated with greenhouse gases. Aerosol particles can affect the climate directly, by scattering or absorption of solar radiation and altering the reflectivity of the planet, and indirectly by acting as cloud condensation (CCN) and ice nuclei (IN), i.e., due to aerosol–cloud interactions. It is well known, for example, that components of marine aerosols can scatter light and act as CCN and IN affecting the radiation budget in the atmosphere as well as cloud physics. Black carbon (BC), in contrast, absorbs radiation readily, warming the atmosphere but also shading the surface. Organic carbon (OC), sometimes called brown carbon or organic matter, has a warming influence on the atmosphere depending on the brightness of the underlying ground. Mineral dust aerosol affects climate through direct and indirect effects. Primary biological aerosol and humic-like substances (HULIS) can affect atmospheric processes such as ice nucleation and cloud drop formation, affecting clouds and precipitation. The outcome of aerosol–cloud interactions depends on the aerosol size distribution and chemistry, on the environmental conditions and cloud regime.

The relevance of effects and the large uncertainties in the understanding of their effects make aerosol research one of the most important field in the climate sciences. The UNEP report (2011) confirms that the current scientific understanding of the aerosol–radiation effects is sufficient to promote the evaluation of measures to limit emissions of the light-absorbing fraction of the aerosol (such as the BC). Moreover, the IPCC report, released in 2018, identifies emission reduction of black carbon, together with methane, an unavoidable measure to keep the global average temperature increase within 1.5 °C by the end of the century.

The purpose of this Special Issue is therefore to disseminate the results of new insights into aerosols composition and physicochemical properties that are related to climate effects.

The topics of interest for this Special Issue include, but are not limited to the following:

  • carbonaceous aerosol
  • black carbon natural and anthropogenic sources identification in different regions
  • secondary inorganic and organic aerosol (SIA, SOA) formation from anthropogenic and natural precursor gases
  • aerosol-cloud interactions
  • assessment of source‘s contribution and composition by tracer-based and ensemble-based source apportionments
  • comparison and merging of remote sensing and ground-level measurements and transport models output
  • numerical models of aerosol transport
  • aerosol optical properties
  • Humic Like Substances (HULIS)

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 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. Applied Sciences is an international peer-reviewed open access semimonthly 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.
