Short summary
Short summary
This work builds a chamber simulation tool that mimics how air chemistry changes inside laboratory reactors, including injected gases, changing light, gas and liquid reactions, wall effects, and dilution. Tests in several chambers reproduced measured changes in reactive species, nitrogen compounds, and ozone, and helped capture how organic particles form. The same chemistry can be reused in larger, global air simulations to assess real-world impact.

Ethyl butyrate and its methylated derivatives are volatile and commonly used aroma compounds, yet their gas-phase chemistry and air quality impact remain poorly characterised. In this work, we investigated the reactivity of these compounds experimentally. We determined temperature-dependent rate coefficients for their reaction with the main atmospheric oxidant, OH, and found that this was the dominant tropospheric loss process. In contrast, direct photolysis is negligible under most conditions.

Short summary
The dynamics of how tyre wear particles behave prior to their entrainment are still poorly understood. In wind tunnel experiments, the particle detachment from an idealized glass substrate was monitored. For particle sizes above 80 μm, smaller and more rounded particles were mobilized by wind shear first, whereas larger and more angular particles require stronger wind shear, highlighting strong surface adhesion and particle morphology as the major factors influencing microplastic detachment.

Short summary
Chemical ionization mass spectrometry is widely used to detect condensable vapors as sulfuric acid and highly oxygenated organic molecules, but results across studies are not always comparable. In summer 2024, an intercomparison campaign involving six instruments was conducted at a boreal forest site. Comparable measurements were achievable when all calibration and correction factors were applied. Instrument behavior depended more on inlet design and operating conditions than reagent ion choice.

Atmospheric simulation chambers enable experiments to be conducted under controlled conditions, improving our understanding of, and ability to predict, changes in the composition of the atmosphere. This is important for assessing air quality and its effects on human health, climate, the environment, and the economy. This paper describes the chambers of the European ACTRIS research infrastructure and discusses topics and directions that can be addressed in future chamber experiments.

Ozone in sampling air can alter the chemical composition of collected ultrafine particles, leading to an inaccurate air quality assessment. We addressed this by developing a ceramic device coated with sodium thiosulfate that eliminates ozone before it reaches the filter. Our results show this tool effectively preserves ozone-sensitive components, such as polycyclic aromatic hydrocarbons, without particle losses. This contributes to more reliable data for air quality research.

We assessed the performance of four cascade impactors for collecting and analyzing organic markers in airborne ultrafine particles (UFPs) under lab and field conditions. The cutoff was influenced by the impactor design and aerosol mixture. Two key factors caused variations in mass concentrations: the evaporation of semi-volatile compounds and the "bounce-off" of larger particles and fragments. Our findings reveal the challenges of analyzing organic marker mass concentrations in airborne UFPs.

Composite analysis of gas concentration before and after rainfall, during the day and night, gives insight into the complex relationship between trace gas variability and precipitation. The analysis helps us to understand the sources and sinks of trace gases within a forest ecosystem. It elucidates processes that are not discernible under undisturbed conditions and contributes to a deeper understanding of the trace gas life cycle and its intricate interactions with cloud dynamics in the Amazon.

Short summary
Here, we study the transport of ultrafine particles (UFPs) from an airport to two new adjacent measuring sites for 1 year. The number of UFPs in the air and the diurnal variation are typical urban. Winds from the airport show increased number concentrations. Additionally, considering wind frequencies, we estimate that, from all UFPs measured at the two sites, 10 %–14 % originate from the airport and/or other UFP sources from between the airport and site.

Short summary
We constructed and characterized a new indoor Teflon atmospheric simulation chamber. We evaluated wall losses, photolysis rates, and secondary reactions of multifunctional photooxidation products in the chamber. To measure these products on-line, we combined chromatographic and mass spectrometric analyses to obtain both isomeric information and a high temporal resolution. For method validation, we studied the formation yields of the main ring-retaining products of toluene.
We constructed and characterized a new indoor Teflon atmospheric simulation chamber. We...
