Special Issue Information

Dear Colleagues,

As demonstrated by the IPCC report, the role played by aerosol particles in climate is crucial since they are one of the main sources of uncertainty in radiative forcing calculations. Although aerosol-light interactions have vital importance in climate change, the understanding of some interactions by the scientific community is low.

Therefore, physical and chemical analyses of radiative absorption and emission by particles of atmosphere are needed in order to reduce uncertainty on radiative forcing caused by aerosols. However, the characterization of aerosol-light interactions is not an easy task. There are multiple parameters that influence this interaction: the existence of many aerosol sources, the great chemical variety of compounds with different properties, vertical distribution, surface albedo, the short residence time in the atmosphere, their spatial heterogeneity or their mixing state. Therefore, field, laboratory or modelling studies are needed in order to improve our knowledge about aerosol–light interactions.

Given the importance of the topic, the open-access journal Atmosphere is hosting a Special Issue to showcase all aspects of research related to radiative absorption and emission by particles of the atmosphere and invites you to submit papers across the broader spectrum of aerosol–light interactions: climate change, remote sensing, radiative transfer modeling, particle scattering or absorption measurements. This Special Issue aims to be an international forum for further research collaboration. Moreover, the submission of research work by interdisciplinary teams and multi-country groups is of significant interest.

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.

A prominent Saharan Air Layer (SAL) was detected over the Northern Atlantic from the West African Coast to the Caribbean Sea in 2007. Data was collected from the Aerosols and Ocean Science Expedition (AEROSE), which encountered a major dust outflow on 13 and 14 May 2007. These observational measurements came from onboard instrumentation and radiosondes that captured the dust-front event from 13 to 14 May 2007. Aerosol backscatter was confined within the Marine Boundary Layer (MBL), with layers detected up to 3 km. Aerosol Optical Depth (AOD) increased by one order of magnitude during the dust front, from 0.1 to 1. Downward solar radiation was also attenuated by 200 W/m2 and 100 W/m2 on the first and second days, respectively. A weaker gradient at and above 500 m from potential temperature profiles indicates a less-defined MBL, and an ambient air temperature of 26 °C on 14 May and 28 °C on 15 May were observed above 500 m, reinforcing the temperature inversion and static stability of the SAL. Subsequent days, clear and boundary-layer cloudy days were observed after the dust front. From 14 to 18 May, a Convective Inhibition (CIN) layer started to form at the top of the MBL, developing into a negative buoyancy from 17 to 23 May, and reinforcing the large-scale anticyclonic atmospheric conditions. These results show that the SAL acts as positive feedback on suppressing deep convection over the tropical Atlantic during this dust outflow and several days after its passage. Full article
