Satellite-Based Retrieval of Aerosol Properties and Its Applications

Dear Colleagues,

Suspended particles in the air or commonly referred to as atmospheric aerosols play a crucial role in climate through its ability to alter Earth’s radiation balance by the means of scattering and absorption of incoming solar radiation—termed as the direct effect, and also through its interactions with clouds, known as the indirect effect.  Alongside its climatic impacts, the concentration of aerosols is also recognized as one the standard measures of air quality, and thus assumes importance in health-related effects. Despite a tremendous advancement in understanding the role of aerosols in climate system through measurements and modeling in last two decades, aerosols still remain an uncertain aspect of climate modeling primarily due to its complex nature and also because of the lack of a comprehensive understanding on its optical and microphysical properties on a global scale.

Ground-based, in situ, and remote sensing measurements have provided the database of aerosol optical and microphysical properties at several locations of the world, albeit over limited spatial areas. In particular, its sparse coverage over the developing countries where the aerosol concentrations are one of the highest in the world has left a big gap in understanding the role of aerosols in climate over these regions. Satellite-based remote sensing of aerosols, on the other hand, provides means of monitoring aerosol loading and its properties on a global scale with frequent observations.

In this call, we encourage submission of the original papers addressing the accomplishments, challenges, and futuristic research in the field of space-based remote sensing of aerosols with a focus on the following topics including but not limited to,

• Recent advancements in retrieval techniques
• Long-term record and trend analysis
• Aerosol radiative forcing
• Applications in air quality monitoring
• Aerosol-cloud interactions
• Implications in 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.
