Special Issue Information
Dear Colleagues,
Aerosol particles are known to interact with clouds by acting as cloud condensation nuclei and affecting cloud radiative properties, with significant implications for global climate change. Currently, the complex interaction among clouds, aerosols, and precipitation remains one of the major sources of uncertainty in climate system models, constraining accurate future climate change predictions. This large uncertainty derives from the incomplete understanding of the aerosol state in natural conditions and the response of clouds to aerosol perturbations due to anthropogenic emissions.
Since March 2020, following the outbreak of the Severe Acute Respiratory Syndrome Coronavirus-2 (COVID-19) pandemic, several countries worldwide have adopted dramatic mitigation actions to contain the spread of the virus. These actions have led to rapid changes in worldwide economic activities such as restrictions on travel and on-site work. As a consequence, anthropogenic emissions of aerosol particles in the atmosphere had experienced unforessen perturbations. These global emission disruptions are likely to affect the climate at both regional and global scales, and represent an unprecedented opportunity to improve the understanding of the impact of perturbations in aerosol properties on climate forcing and aerosol-cloud interactions.
The special issue focuses on all aspects of aerosol influence on the atmosphere during the COVID-19 pandemic. These include, but not limited to, experimental assessment of new sensors, monitoring network, and observation platform, the deployment to specifically support the observation during pandemic, observational and model analysis of changes in aerosol properties, and lessons learned to decision-making support systems. Contributions discussing the implications of reduced anthropogenic aerosol emissions on cloud systems are especially welcome.

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.
