Only a small fraction of airborne particles acts as seeds for cloud droplets and influence climate, yet the processes controlling their abundance remain unclear. Field measurements in Cyprus reveal that particles smaller than 20 nanometers can rapidly shrink. This shrinkage was linked to dilution and possible evaporation of organic compounds, identifying a previously overlooked nanoparticle sink that may reduce cloud-forming particles and weaken aerosol-driven cooling.

Aerosols are tiny particles that affect climate by scattering and absorbing sunlight and altering clouds. Much of the uncertainty in their climate effect comes from poorly known emissions. Here we provide a new global estimate of aerosol emissions using PACE/SPEXone satellite observations of aerosol amount, size, and absorption. Combining these with a global aerosol climate model through data assimilation, we find a substantial update to current estimates, suggesting stronger aerosol cooling.

Coarse-mode aerosols, like dust and bioaerosols, play important roles in environmental and climate processes. We measured fluorescence and morphological properties of key coarse-mode particle types, compared them with previous characterizations, and trained machine learning models with these data to classify unknown particles. This algorithm improves bioaerosol identification and successfully reproduces the annual bioaerosol cycle previously identified in a year of observations from Svalbard.

We studied chemical compositions and chromophores of brown carbon aerosol from combustion emission before and after photooxidation using an oxidative flow reactor. The chromophore and chemical composition of brown carbon were determined by excitation-emission spectroscopy and mass spectrometry. This work helps to get a better understanding of evolution process of the chromophores from primary combustion emissions during the real atmospheric transportation.

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.

We investigate how temperature (213–313K) affects secondary organic aerosol (SOA) particles derived from isoprene and α-pinene mixtures. Isoprene's suppression on α-pinene dimer formation varied with temperatures. Particles formed at higher temperatures are more oxidized yet more volatile than those formed at lower temperatures and then warmed. This work highlights the need to consider both temperature and biogenic vapor interaction to accurately describe SOA formation, aging, and global burden.

This study presents size-resolved mass concentrations of inorganic ions, levoglucosan, and total carbon of aerosol particles from a coastal station at the Dutch Wadden Sea as well as isotopic signatures (13C and 14C) of organic carbon. Aerosol advected out to the North Sea consists mainly of ammonium nitrate and carbonaceous material. Fossil sources contribute a small mass fraction to organic carbon. 13C signatures differ strongly from those of primary sources, highlighting secondary processes.

Combusting hydrogen alongside carbon-based fuels has been proposed to reduce CO2 emissions. In this work, we investigate how this affects the emitted particles, using a model flame. Increasing hydrogen leads to smaller particles containing a higher of organic material and less of the of the strongly light absorbing elemental carbon. However, the organic material shows considerable light absorption at shorter visible wavelength and in the UV.

Urban ultrafine particles (<100 nm) sources and growth mechanisms remain poorly constrained. Measurements in a Munich street canyon reveal that UFP number concentrations peak at night due to traffic and cooking emissions trapped under a shallow boundary layer. Particle growth is instead driven by condensation of organic vapours with strong seasonal shifts: biogenic and barbeque charcoal biomass-burning compounds dominate in summer, while combustion-related organics control winter growth.

We analyzed Munich air samples across seasons to identify pollution sources. Traffic contributes less to particles than expected, while biomass burning dominates year-round. Summer barbecuing and winter heating release significant pollution. Monoterpene emissions from plants produce particles at night. Effective air quality improvement requires year-round strategies targeting biomass burning, not just vehicles. Understanding each city's pollution patterns is essential for public health.

We identify a previously unrecognized class of synthetic organic compounds, large molecular methylsiloxanes, in ambient aerosols across diverse environments in three countries. These compounds are present at substantial levels, primarily originating from traffic emissions related to engine lubrication. Their high abundance and significant daily human exposure suggest potential, yet still poorly understood, implications for both health and climate.

We studied several major dust storms that traveled from the Sahara to Europe using ground-based light measurements, sunlight sensors, particle counters, and a modern weather and dust model. We reveal when the dust arrived, how it moved and mixed in the air, and why each event behaved differently. Our results help improve forecasts of dust episodes that influence air quality, visibility, and solar energy across Europe.

Back carbon is an atmospheric pollutant from combustion and contributes to the Arctic warming. However, its properties change as it travels through the atmosphere, affecting its impact. We recreated Arctic transport conditions in a laboratory to study how black carbon evolves over time. Our findings show that temperature and altitude strongly influence its transformation, providing key insights for improving climate models and understanding Arctic pollution.

This study examines how environmental factors (sunlight, pH, salinity, and surface chemistry) affect air–water interface reactions. Using a surface-specific technique, sum-frequency generation (SFG) spectroscopy, we found that compounds like 4-benzoylbenzoic acid (4-BBA) not only act as photosensitizers but also generate new surface-active products under UV light. These reactions have implications for oceans, lakes, and clouds, providing crucial insights for modeling natural processes.

Water vapor is a strong greenhouse gas, and accurate measurements of its concentration in the upper atmosphere (~8–25 km altitude) are crucial for reliable climate predictions. We investigated the performance of four airborne hygrometers, deployed on aircraft or stratospheric balloon platforms and based on different techniques, in a climate simulation chamber. The results demonstrate the high accuracy and reliability of the involved sensors for atmospheric monitoring and research applications.

It is of increasing importance to monitor nitrate pollution that can harm ecosystems. However, commonly used aerosol monitoring equipment cannot distinguish inorganic from organic forms of nitrate, which may have different consequences for the environment. We describe a method to differentiate types of nitrates that can be applied to ambient monitoring to improve understanding of its formation and impact.

The chemical composition of brown carbon in the particle and gas phase was determined by mass spectrometry. BrC in the gas phase was mainly controlled by secondary formation and particle-to-gas partitioning. BrC in the particle phase was mainly from secondary formation. This work helps to get a better understanding of diurnal variations and the sources of brown carbon aerosol at a rural location in central Europe.

Biogenic volatile organic compounds (BVOCs) and organic aerosol (OA) particles were measured online in a stressed spruce-dominated forest. OA was mainly attributed to the monoterpene oxidation products. The mixing ratios of BVOCs were higher than the values previously measured in other temperate forests. The results demonstrate that BVOCs are influenced not only by meteorology and biogenic emissions but also by local anthropogenic emissions and subsequent chemical transformation processes.

Single-particle mass spectrometry (SPMS) is commonly used to measure the chemical composition and mixing state of aerosol particles. Intercomparison of SPMS instruments was conducted. All instruments reported similar size ranges and common spectral features. The instrument-specific detection efficiency was found to be more dependent on particle size than type. All differentiated secondary organic aerosol, soot, and soil dust but had difficulties differentiating among minerals and dusts.

The vertical distribution of aerosol optical properties is important for their effect on climate. This is usually measured by lidar, which has limitations, most notably the assumption of a lidar ratio. Our study shows that routine surface-level aerosol measurements are able to predict this lidar ratio reasonably well within the lower layers of the atmosphere and thus provide a relatively simple and cost-effective method to improve lidar measurements.

This study presents concurrent online measurements of organic gas and particles (VOCs and OA) at a forested site in summer. Both VOCs and OA were largely contributed by oxygenated organic compounds. Semi-volatile oxygenated OA and organic nitrate formed from monoterpenes and sesquiterpenes contributed significantly to nighttime particle growth. The results help us to understand the causes of nighttime particle growth regularly observed in summer in central European rural forested environments.

Particulate matter (PM) is a harmful air pollutant that depends on the complex mixture of natural and anthropogenic emissions into the atmosphere. Thus, in different regions and seasons, the way that PM is formed and grows can differ. In this study, we use a combined statistical analysis of the chemical composition and particle size distribution to determine what drives particle formation and growth across seasons, using varying wind directions to elucidate the role of different sources.

Polar stratospheric clouds (PSCs) play an important role in the depletion of stratospheric ozone. They can consist of different chemical species, including crystalline nitric acid hydrates. We found that mineral dust or meteoric ablation material can efficiently catalyse the formation of a specific phase of nitric acid dihydrate crystals. We determined predominant particle shapes and infrared optical properties of these crystals, which are important inputs for remote sensing detection of PSCs.

This study investigates how ice grows directly from vapor in cirrus clouds by comparing observations of populations of ice crystals growing in a cloud chamber against models developed in the context of single-crystal laboratory studies. We demonstrate that previous discrepancies between different experimental measurements do not necessarily point to different physical interpretations but are rather due to assumptions that were made in terms of how experiments were modeled in previous studies.

We studied brown carbon aerosol during typical summer and winter periods in downtown Karlsruhe in southwestern Germany. The chromophore and chemical composition of brown carbon was determined by excitation–emission spectroscopy and mass spectrometry. The chromophore types and sources were substantially different in winter and summer. Humic-like chromophores of different degrees of oxidation dominated and were associated with molecules of different molecular weight and nitrogen content.

Landscape fires are a substantial emitter of greenhouse gases and aerosols. Previous studies have indicated savanna emission factors to be highly variable.

We present a drone-based method that enables the collection of a large amount of high-quality emission factor measurements that do not have the biases of aircraft or surface measurements.

We study secondary organic aerosol (SOA) from β-caryophyllene (BCP) ozonolysis with and without nitrogen oxides over 213–313 K in the simulation chamber. The yields and the rate constants were determined at 243–313 K. Chemical compositions varied at different temperatures, indicating a strong impact on the BCP ozonolysis pathways. This work helps to better understand the SOA from BCP ozonolysis for conditions representative of the real atmosphere from the boundary layer to the upper troposphere.

A LED-based light source has been constructed for the AIDA simulation chamber at the Karlsruhe Institute of Technology. It allows aerosol formation and ageing studies under atmospherically relevant illumination intensities and spectral characteristics at temperatures from –90 °C to 30 °C with the possibility of changing the photon flux and irradiation spectrum at any point. The first results of photolysis experiments with 2,3-pentanedione, iron oxalate and a brown carbon component are shown.

Landscape fires are a major source of greenhouse gases and aerosols, particularly in sub-tropical savannas. Stable carbon isotopes in emissions can be used to trace the contribution of C3 plants (e.g. trees or shrubs) and C4 plants (e.g. savanna grasses) to greenhouse gases and aerosols if the process is well understood. This helps us to link individual vegetation types to emissions, identify biomass burning emissions in the atmosphere, and improve the reconstruction of historic fire regimes.

We performed experiments in the CLOUD chamber at CERN at low temperatures to simulate new particle formation in the upper free troposphere (at −30 ºC and −50 ºC). We measured the particle and gas phase and found that most of the compounds present in the gas phase are detected as well in the particle phase. The major compounds in the particles are C8–10 and C18–20. Specifically, we showed that C5 and C15 compounds are detected in a mixed system with isoprene and α-pinene at −30 ºC, 20 % RH.

We investigate ice-nucleating particle properties at Jungfraujoch during the 2017 joint INUIT/CLACE field campaign, to improve the knowledge about those rare particles in a cloud-relevant environment. By quantifying ice-nucleating particles in parallel to single-particle mass spectrometry measurements, we find that mineral dust and aged sea spray particles are potential candidates for ice-nucleating particles. Our findings are supported by ice residual analysis and source region modeling.

Short summary
Sea spray aerosol plays an important role in climate and atmospheric chemistry, yet sea salt is rarely quantified by online mass spectrometers due to its refractory nature. This study shows that a capture vaporizer time-of-flight aerosol chemical speciation monitor can detect sea salt aerosol using Na and NaCl fragments. Laboratory and field results demonstrate robust real-time measurements of NaCl surface area, while accurate mass concentrations require particle size information.
