Special Issue Information

Dear Colleagues,

Atmospheric radicals, including HOx, ROx (where R is an organic substituent), NOx, and XOx (X = Cl, Br, I), play pivotal roles in the oxidizing capacity of the atmosphere, and have a profound effect on air quality, human health, and, potentially, climate change. However, there is still much to discover in atmospheric radical chemistry in terms of their sources, concentration levels, physical and chemical transformations, measurement techniques, etc. A comprehensive understanding of atmospheric radical chemistry and its effects is essential to comprehending the scientific changing principles governing the trace species that surround our planet.

This Special Issue aims to contribute to our current understanding of the roles of different radicals in their atmospheric context, their effects in secondary pollutants’ formation and potentially climate change, as well as new techniques to quantify their concentrations and capture the related chemistry reactions. Topic of specific interest include, but are not limited to, the following:

  • Radical-related day-time and night-time oxidation chemistry (conducted both in laboratory and ambient studies).
  • Development and application of measurement techniques for atmospheric radicals.
  • Concentration levels of atmospheric radicals under different environmental conditions and associated mechanisms.
  • Measuring and model simulations in reproducing atmospheric radical chemistry.
  • Radical chemistry related to climate feedbacks (i.e., greenhouse gases formation related to atmospheric radicals).
  • Ambient radical reactivities.
  • Organic photochemical reactions of environmental interest.
  • Atmospheric radical chemistry affected by heterogeneous processes (i.e., HO2 and halogen radicals uptake by ambient aerosols).

We very much look forward to your submissions.

The surface atmospheric O3 concentration in Kunming shows a significant upward trend, with high values mainly occurring in March–May. Volatile organic compounds (VOCs) are one of the most important precursors of O3. However, the sources of VOCs are complex and difficult to identify. In order to understand the pollution levels, the spatial distribution characteristics, and possible sources of VOCs, we conducted simultaneous offline sampling at representative sites in six different functional areas of Kunming using SUMMA canisters for one week. The VOC samples were analyzed via GC/MS. The VOC data were analyzed (using the feature ratio method, ozone formation potential (OFP), and Positive Matrix Factorization (PMF) model). Some important conclusions were drawn. Firstly, VOCs during the spring in Kunming were mainly derived from oxygenated VOCs, aromatic hydrocarbons, and halogenated hydrocarbons, with significant spatial differences. Secondly, we found that the potential for atmospheric ozone formation is higher in Kunming for aromatic hydrocarbons and oxygenated VOCs. Finally, the results of the Positive Matrix Factorization model (PMF) showed that Kunming’s ambient atmospheric VOCs mainly originate from anthropogenic source emissions. These conclusions can provide useful reference information for O3 pollution control in Kunming. Full article
