In this work, we compare the two most widely used online XRF monitors for ambient elemental analysis, the Xact625i and PX-375. We found strong correlations between the online instruments and the reference method (better so for the Xact625i), while in terms of absolute concentrations, some elements were over- and underestimated. Overall, we determined both instruments can be used as powerful tools to produce high-time resolution elemental data for use in air quality monitoring.

This study examines winter air quality in Central Europe, focusing on the impact of domestic heating. Using a chemical transport model and measurements, it was found that the model underestimated organic particle concentrations. This was due to an underestimation of gases from domestic heating that form secondary organic particles. Improving the model by increasing these emissions and the particle formation led to better results, demonstrating the important role of heating emissions in winter.

A unique dataset of concentrations and sources of polycyclic aromatic hydrocarbons (PAHs) and their alkylated, oxygenated and nitrated derivatives, in total 74 individual species, in the marine atmosphere is presented. Exposure to these substances poses a major health risk. We found very low concentrations over the Arabian Sea, while both local and long-range-transported pollution caused elevated levels over the Mediterranean Sea and the Arabian Gulf.

We trained machine learning models to estimate the number of aerosol particles large enough to form clouds and generated daily estimates for the entire globe. The models performed well in many continental regions but struggled in remote and marine areas. Still, this approach offers a way to quantify these particles in areas that lack direct measurements, helping us understand their influence on clouds and climate on a global scale.

Understanding how volatile organic compounds from plants and soils contribute to aerosol particles is essential for predicting air quality and climate effects. This study used advanced mass spectrometry to analyze particles formed from these compounds under controlled conditions. By identifying distinct chemical fingerprints, we can trace particle sources and reactions more accurately, improving our understanding of particle formation processes in the atmosphere.

This study compares carbonaceous aerosols source apportionment at paired traffic and background locations in urban environment (Strasbourg, France). Positive matrix factorization was applied (individually and in a combined input dataset) to aerosol mass spectrometry measurements at both sites, providing notably insights into the challenges of attributing real sources to organic aerosol (OA) factors and the impact of instrumental result specificities leading to differences in OA mass spectra.

The summer of 2022 has been considered a proxy for future climate scenarios due to its hot and dry conditions. In this paper, we use the measurements from the Atmospheric Chemistry of the Suburban Forest (ACROSS) campaign, conducted in the Paris area in June–July 2022, along with observations from existing networks, to evaluate a 3D chemistry transport model (WRF–CHIMERE) simulation. Results are shown to be satisfactory, allowing us to explain the gas and aerosol variability at the campaign sites.

This study investigates how to better understand and predict organic aerosols, which are tiny particles in the air that can affect our health and climate. By using advanced computer models, we examined the impact of different emissions and environmental conditions on these aerosols in Central Europe. Our findings show that including specific emissions significantly improved the accuracy of our predictions.

Air pollution affects human health and climate, but most measurements focus on ground-level data. We used drones to measure black carbon and particle concentrations at different heights in urban and rural areas across seasons. Our results show that pollution distribution varies with altitude and season, influenced by weather and emissions. We also found that controlling humidity is crucial for accurate black carbon measurements. These findings help improve air quality monitoring and policies.

The spectral complex refractive index (CRI) and single scattering albedo were retrieved from submicron aerosol measurements at three sites within the greater Paris area during the ACROSS field campaign (June–July 2022). Measurements revealed urban emission impact on surrounding areas. CRI full period averages at 520 nm were 1.41 – 0.037i (urban), 1.52 – 0.038i (peri-urban), and 1.50 – 0.025i (rural). Organic aerosols dominated the aerosol mass and contributed up to 22 % of absorption at 370 nm.

This study explored pesticides in the air at a rural site in the Czech Republic. Older pesticides, banned decades ago, are still found due to their release from soils, especially in summer. While levels of many have declined over time, some show new emissions from local or distant sources. Newer pesticides peaked during application seasons but declined after bans, though traces lingered. These findings highlight the lasting impacts of pesticide use and the importance of regulations.

The ALADIN regional climate model at 12.5 km resolution allows us to study the evolution of surface solar radiation (SSR) and key associated atmospheric parameters. Over northern France and Benelux, influenced by anthropogenic aerosols and cloudy conditions, regional evaluation of recent hindcast simulations shows satisfying results and high spatial variability. Future SSR evolution by the end of the century for two contrasting CMIP6 scenarios highlights large decreases in SSR for SSP3-7.0.

Carbonate carbon (CC) is not negligible in Arctic total suspended particles (TSP). If not considered, CC biases the contribution of elemental and organic carbon. CC content in TSP was strongly reflected in the δ13C values of total carbon (TC). Carbon contribution from CaCO3 supports strong dependence of CC and δ13C on Ca. Finally, two hypothetical CC sources were identified based on the analysis of air mass back trajectories – dust resuspension and marine microorganisms.

Long-term (2015–2021) quasi-continuous measurements have been obtained at 13 French urban sites using online mass spectrometry, to acquire the comprehensive chemical composition of submicron particulate matter. The results show their spatial and temporal differences and confirm the predominance of organics in France (40–60 %). These measurements can be used for many future studies, such as trend and epidemiological analyses, or comparisons with chemical transport models.

The performances of different particle lung-deposited surface area (LDSAal) measurement methods (Partector, ELPI+, SMPS/DMPS) were compared in ambient conditions. As LDSAal is a health-relevant metric and rather easy to utilise in air quality monitoring, it is crucial to know how the different methods agree, as there are clear differences in their operation. In all, a comparison of different methods can be complicated; still, the methods agree rather well in terms of local pollution (< 400 nm).

Multi-annual in situ observations were combined with back trajectory and emissions inventories to study black and brown carbon (BC, BrC) sources in the north of France. Results show BC to be mainly originated from vehicular traffic (31 %), shipping (25 %), and residential heating (21 %). Also, a significant decrease of the BrC component from residential heating is observed after 24 h of atmospheric aging. These results should lead to better climate and air pollution mitigation strategies.

Many European people are still exposed to levels of air pollution that can affect their health. COVID-19 lockdowns in 2020 were used to assess the impact of the reduction in human mobility on air pollution across Europe by comparing measurement data with values that would be expected if no lockdown had occurred. We show that lockdown measures did not lead to consistent decreases in the concentrations of fine particulate matter suspended in the air, and we investigate why.

Ultrafine particles (UFPs) are particles with an aerodynamic diameter of 100 nm or less and negligible mass concentration but are the dominant contributor to the total particle number concentration. The present study aims to better understand the environmental factors favoring or inhibiting atmospheric new particle formation (NPF) over Lille, a large city in the north of France, and to analyze the impact of such an event on urban air quality using a long-term dataset (3 years).

This work presents the differences resulting from two techniques (rolling and seasonal) of the positive matrix factorisation model that can be run for organic aerosol source apportionment. The current state of the art suggests that the rolling technique is more accurate, but no proof of its effectiveness has been provided yet. This paper tackles this issue in the context of a synthetic dataset and a multi-site real-world comparison.

Aerosol particles are a complex component of the atmospheric system the effects of which are among the most uncertain in climate change projections. Using data collected at 62 stations, this study provides the most up-to-date picture of the spatial distribution of particle number concentration and size distribution worldwide, with the aim of contributing to better representation of aerosols and their interactions with clouds in models and, therefore, better evaluation of their impact on climate.

Measurements of black carbon must be conducted with instruments operating in quality-checked and assured conditions to generate reliable and comparable data. Here, 23 Aethalometers monitoring black carbon mass concentrations in European networks were characterized and intercompared. The influence of different aerosol sources, maintenance activities, and the filter material on the instrumental variabilities were investigated. Good agreement and in general low deviations were seen.

Short summary
By examining individual episodes of high mass and number concentrations, we show that the seasonality in the physicochemical properties of aerosol particles was caused by the sources' diversity and was related to the different air masses and meteorology. We also confirmed the relation between particle size and age that is reflected in oxidation state and shape (difference in densities; effective vs. material). The results have general validity and thus transcend the study regional character.
By examining individual episodes of high mass and number concentrations, we show that the...
