Special Issue "Short-Lived Climate Pollutants (SLCPs): Characterization, Sources, and Atmospheric Transformation"

Dear Colleagues,

Short-lived climate pollutants (SLCPs), including black carbon, organic carbon, sulfate, and nitrate, as well as gases like tropospheric ozone, methane, and hydrofluorocarbons, have short atmospheric lifetimes. However, they have a significant impact on air quality, food, water, and economic security for much of the world, both directly and indirectly through their negative effects on climate, public health, and agriculture. Due to their very short lifetime in the atmosphere, which ranges from a few days to a few decades, regulating SLCPs can rapidly slow the rate of global temperature rise, complement efforts to reduce carbon dioxide emissions, and limit warming to less than 2°C. The resources and tools necessary to mitigate the effects of SLCPs are already at our disposal, and they are accessible, realistic, and economical. Implementing them can have positive effects on the climate right away, aid in the completion of many global Sustainable Development Goals (SDGs), and have positive impacts on human health and economy for millions. Due to the variety of potential SLCP precursors, human activities, and the complexity of atmospheric chemistry, gaps in our knowledge remain regarding the atmospheric evolution and transformation over the globe.

This Special Issue aims to discuss the observation of SLCPs at local, regional, and global levels, as well as their characterization, origins, and atmospheric transformation. We are especially interested in articles based on the understanding, environmental effects, and variability of SLCPs by long-term measurements combined with intensive campaigns and laboratory experiments to elucidate the relevant processes involved in rural and urban areas. This will lead to improved modeling tools to specifically assess the influences of SCLPs on climate, agriculture, health, and many SDGs.

We invite authors to contribute to the following topics:

• Key SLCPs, including black carbon, brown carbon, and ozone precursors and their characterization in urban and rural areas.
• Long-term field evaluation of low-cost BC, VOCs and radicals sensors.
• Investigation of the transformation of SLCPs and its impact on climate with different meteorological conditions.
• Satellite data to detect sources of key SLCPs (e.g., BC, ozone, CH₄) and their impact on local and regional air quality.
• Field and laboratory experiments for SCLPs and their impact on climate radiative forcing.

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 2000 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.
