Special Issue Information

Dear Colleagues,

Atmospheric chemistry and related topics have been attracting continuous interest over the last few decades. Climate variability and changes have impacted the lifecycles, unbalancing the concentration of the constituents of the Earth’s atmosphere. The budget of gases and particles in the atmosphere is strongly affected by these modifications, further influencing atmospheric processes. The reactivity, composition, and dynamics of trace gases in the atmosphere have challenged our understanding of the chemistry and physics of atmospheric processes. Biogenic and anthropogenic sources of volatile organic compounds are more complex than decades ago, intriguing scientists.

With this Special Issue, we invite you to submit your scientific research articles, which cover a broad range of topics on chemistry and physics of atmosphere from gas-phase reactivity and degradation mechanism to secondary organic aerosol formation. Your contributions may include recent experimental work and modeling studies. The topics of interest are around the aim to better understand atmospheric processes but are not limited to:

  • Ozone, OH and NO3 radicals, and chlorine atoms gas-phase kinetics;
  • Investigations on the relevant atmospheric photochemical processes;
  • Structure–activity relationship and reactivity studies;
  • Gas-phase mechanistic investigations of chemical reactions;
  • VOC chemical degradation and product formation;
  • Modeling applications of reaction kinetics and mechanisms;
  • Formation of secondary organic aerosols from gas phase reactions of VOCs—size distribution, formation yield, and modeling studies;
  • Theoretical and/or computational methodology of atmospheric general 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.

We investigated the kinetics, mechanism and secondary organic aerosols formation of the ozonolysis of trans-2-pentenal (T2P) using four different reactors with Fourier Transform InfraRed (FTIR) spectroscopy and Gas Chromatography (GC) techniques at T = 298 ± 2 K and 760 Torr in dry conditions. The rate coefficients and branching ratios were also evaluated using the canonical variational transition (CVT) state theory coupled with small curvature tunneling (CVT/SCT) in the range 278–350 K. The experimental rate coefficient at 298 K was (1.46 ± 0.17) × 10−18 cm3 molecule−1 s−1, in good agreement with the theoretical rate. The two primary carbonyls formation yields, glyoxal and propanal, were 57 ± 10% and 42 ± 12%, respectively, with OH scavenger compared to 38 ± 8% for glyoxal and 26 ± 5% for propanal without OH scavenger. Acetaldehyde and 2-hydroxypropanal were also identified and quantified with yields of 9 ± 3% and 5 ± 2%, respectively, in the presence of OH scavenger. For the OH production, an upper limit of 24% was estimated using mesitylene as OH tracer. Combining experimental and theoretical findings enabled the establishment of a chemical mechanism. Finally, the SOA formation was observed with mass yields of about 1.5%. This work provides additional information on the effect of the aldehyde functional group on the fragmentation of the primary ozonide. Full article
