Marine Aerosols and Their Effects on Aerosol-Cloud Interactions

Dear Colleagues,

Aerosols and clouds absorb and scatter solar and terrestrial radiation and play important roles in the Earth’s energy balance. Aerosol particles participate in the Earth’s radiation budget and the climate system via two pathways: radiative forcing due to aerosol–radiation interactions that arise from direct scattering and absorption of solar and terrestrial radiation by aerosols; and radiative forcing from aerosol–cloud interactions  that arise from aerosols acting as cloud condensation nuclei (CCN) and ice nuclei (IN). In the marine environment, aerosols are generated through the air–sea exchange process, including primary emissions and secondary formations. Marine aerosols are important for determining the physical and chemical characteristics of the Earth’s atmosphere and for their interactions with the climate system. Under global warming, gas precursors of marine aerosols may vary to a certain degree, and the respone of natural aerosols may amplify or attenutate the effects of radiative forcing. Moreover, the response of clouds to aerosol changes may be much more complex than that understood decades ago. The links between marine biology, cloud properties, and climate are complex.

This Special Issue calls for papers that explore topics that focus on marine aerosols and their effects on aerosol–cloud interactions through field observations and model simulations. This research will help us better understand the role of marine aerosols and their effect on climate change.

The aim of this Special Issue is to gather the latest research on marine aerosols and their climate effects. Potential research topics include, but are not limited to, the following:

• Chemical and physical properties of marine aerosols;
• Number of concentrations and size distributions of marine aerosols;
• Marine biogenic volatile organic compounds;
• Marine aerosol particles, gas precursors, and new particle formation;
• Correlations between phytoplankton dynamics, aerosols, and cloud microphysical processes;
• Observations and model simulations of DMS and aerosol sulfate;
• Aerosols acting as CCN and IN in the lower marine atmosphere;
• Marine aerosols and climate change.

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.
