Atmospheric Chemistry and Physics (ACP) is an international scientific journal dedicated to the publication and public discussion of high-quality studies investigating the Earth's atmosphere and the underlying chemical and physical processes. It covers the altitude range from the land and ocean surface up to the turbopause, including the troposphere, stratosphere, and mesosphere.
The main subject areas comprise atmospheric modelling, field measurements, remote sensing, and laboratory studies of gases, aerosols, clouds and precipitation, isotopes, radiation, dynamics, biosphere interactions, and hydrosphere interactions (for details see journal subject areas). The journal scope is focused on studies with general implications for atmospheric science rather than investigations that are primarily of local or technical interest.
Light absorbing organic aerosols (BrC) absorb sunlight thereby influencing climate; however, understanding of the link between their optical properties and environmental variables remains limited. Our chamber experiment results suggest that variables including NOx concentration, RH level, and photolysis time have considerable influence on secondary BrC optical properties. The results contribute to a more accurate characterization of the impacts of aerosols on climate, especially in urban areas.

A total of 480 microorganisms collected from 39 clouds sampled in France were isolated and identified. This unique collection was screened for biosurfactant production by measuring the surface tension. 41 % of the tested strains were active producers. Pseudomonas, the most frequently detected genus in clouds, was the dominant group for the production of biosurfactants. Further, the potential impact of the production of biosurfactants by cloud microorganisms on atmospheric processes is discussed.

This paper presents an analysis of unusually long and continuous time series (82 yrs) of visibility in a urban environment, namely Athens. Visibility is shown to be a good proxy to follow the evolution of particulate pollution in the long-term in the absence of direct aerosol measurements that can be compared only over the most recent period. The paper shows interesting evolutions related to the socio-economic local history and, by comparison to a distant island site, demonstrates the major control of large-scale conditions on the aerosol load even in a large and densely populated urban environment.

Using a coupled tropospheric chemistry-aerosol microphysics model this research paper investigates the effect of variations in aviation fuel sulfur content (FSC) on surface PM2.5 concentrations, increases in aviation-induced premature mortalities, low-level cloud condensation nuclei and radiative effect.
When investigating the climatic impact of variations in FSC the ozone direct radiative effect, aerosol direct radiative effect and aerosol cloud albedo effect are quantified.

HF, the dominant stratospheric fluorine reservoir, results from the atmospheric degradation of anthropogenic species such as CFCs, HCFCs, and HFCs. All are strong greenhouse gases, and CFCs and HCFCs deplete stratospheric ozone. We report the comparison of HF global distributions and trends measured by the ACE-FTS and HALOE satellite instruments with the output of SLIMCAT, a chemical transport model. The global HF trends reveal a slowing down in the rate of increase of HF since the 1990s.

Copernicus Publications and the Leibniz Association have agreed on a central billing of article processing charges (APCs) to facilitate the publication procedure for authors. So far three Leibniz institutes are participating in this agreement.
