Special Issue Information

Dear Colleagues,

This Special Issue is the second volume of the series of publications dedicated to " Natural Sources Aerosol Remote Monitoring”

(https://www.mdpi.com/journal/atmosphere/special_issues/7LS1CU8WV4) published in Atmosphere in 2023.

Atmospheric aerosol particles from both anthropogenic and natural sources represent major uncertainties in our knowledge of atmospheric processes and of the Earth radiative balance. They also play a strong role in the dynamics of climate change and in human health and safety.

Although there is a strong interest in the study of anthropic and natural components, the weight of the latter is still poorly investigated, which causes an unsatisfactory understanding of the interactions of natural aerosols in the terrestrial ecosystem and in their radiative effects. In particular, natural sources have a high contribution to background aerosol concentrations, and therefore, their accurate quantification is essential for the study of the mechanisms, interactions and impact of anthropogenic aerosols within the Earth system. In addition, this background is variable not only due to the uncertainties introduced by the unpredictability of natural events such as volcanic eruptions, desert sand transport, etc., but also as a consequence of human intervention, which is contributing to an increase not only in anthropogenic aerosols but also those of natural origin.

This Special Issue aims to combine the contributions of various studies, which, through the use of remote sensing techniques, investigate aerosols of natural origin and increase knowledge about their properties and mechanisms.

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.

Identifying the types and vertical distribution of aerosols plays a significant role in evaluating the influence of aerosols on the climate system. Based on the aerosol optical properties obtained from Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO), this study analyzed the long-term aerosol characteristics of seven cities in East Asia (Ulaanbaatar, Beijing, Lanzhou, Shanghai, Lhasa, Hong Kong, and Bangkok) from 2007 to 2021, including the spatiotemporal variations of aerosol optical depth (AOD), the vertical stratification characteristics of aerosols, and the main aerosol subtype. The results showed that, except for Lhasa, the AOD values of all cities exhibited a trend of initially increasing and then decreasing over the years. Except for Shanghai, the high values of AOD in the other cities occurred in the spring and summer seasons, while the low values occurred in the autumn and winter seasons. In all four seasons, the AOD contribution within the 1–3 km range accounted for more than 50% of the total. In the autumn and winter seasons, this proportion reached over 80%. The main types of aerosols and their contributions varied at different altitudes. Overall, dust, polluted continental/smoke, polluted dust, and elevated smoke dominated in all aerosol layers across each city. On the other hand, clean marine, clean continental, and dusty marine had very small proportions, accounting for less than 5% of all the cities’ aerosol layers. Full article
