This paper is about the eighteen-months measurement of Non-Methane Hydrocarbons (NMHC) at Marseille, were there was no measurement since early 2000 despite the impact of NMHC on air quality and climate. The traffic related sources are the first contributor to NMHC concentrations in Marseille and shipping strongly contribute to the formation of aerosols. Finally, the lockdown due to the Covid-19 had an impact on NMHC concentrations reaching a fifty percents decreasing for traffic-related sources.

We investigated tropospheric ozone spatial variability and trends from 2005 to 2019 and related those to ozone precursors on global and regional scales. We also investigate the spatiotemporal characteristics of the ozone formation regime in relation to ozone chemical sources and sinks. Our analysis is based on remote sensing products of the tropospheric column of ozone and its precursors, nitrogen dioxide, formaldehyde, and total column CO, as well as ozonesonde data and model simulations.

Using measurements of various trace gases in a suburban forest near Paris in the summer of 2022, we were able to gain insight into the sources and sinks of NOx (NO+NO2) with a special focus on their nighttime chemical and physical loss processes. NO was observed as a result of nighttime soil emissions when O3 levels were strongly depleted by deposition. NO oxidation products were not observed at night, indicating that soil and/or foliar surfaces are an efficient sink of reactive N.

In order to study aerosols in environments influenced by anthropogenic and biogenic emissions, we performed analysis of samples collected during ACROSS (Atmospheric Chemistry Of the Suburban Forest) campaign in the summer 2022 in the Paris greater area. After analysis of the chemical composition by means of total carbon determination and high resolution mass spectrometry, this work highlights the influence of anthropogenic inputs into the chemical composition of both urban and forested areas.

A summer campaign in a Mediterranean port examined pollution caused by ships. Two stations in the port measured pollution levels and captured over 350 ship plumes to study their chemical composition. Results showed that pollution levels, like ultra-fine particles, were higher in the port than in the city and offer a strong support to improve emission inventories. These findings may also serve as reference for assessing the benefits of a Sulphur Emission Control Area in the Mediterranean in 2025.

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 the urban emission impact on the surrounding areas. The CRI full period averages at 520 nm were 1.41–0.037i (urban), 1.52–0.038i (peri-urban), 1.50−0.025i (rural). Organic aerosols dominated the aerosol mass and contributed up to 22% of absorption at 370 nm.

In the scope of a field campaign in a suburban forest near Paris in the summer of 2022, we measured the reactivity of the nitrate radical NO3 towards biogenic volatile organic compounds (BVOCs; e.g. monoterpenes) mainly below but also above the canopy. NO3 reactivity was the highest during nights with strong temperature inversions and decreased strongly with height. Reactions with BVOCs were the main removal process of NO3 throughout the diel cycle below the canopy.

Accurate and comparable measurements of oxygenated organic compounds (OVOCs) are crucial to assess tropospheric ozone burdens and trends. However, monitoring of many OVOCs remains challenging because of their low atmospheric abundance and lack of stable and traceable calibration standards. This research describes the calibration standards developed for selected OVOCs at low amount of substance fractions (<100 nmol mol-1) to transfer traceability to the international system of units to the field.

This study examines BTEX (benzene, toluene, ethylbenzene, xylenes) pollution in urban areas across 7 European countries. Analyzing data from 22 monitoring sites, we found traffic and industrial activities significantly impact BTEX levels, with peaks during rush hours. Despite improvements, the risk from BTEX exposure remains moderate, especially in high-traffic and industrial zones. It highlights the need for targeted air quality management to protect public health and improve urban air quality.

Atmospheric volatile organic compounds (VOCs) constitute many species, acting as precursors to ozone and aerosol. Given the uncertainties in VOC emissions, lack of evaluation studies, and recent changes in emissions, this work adapts the EMEP MSC-W to evaluate emission inventories in Europe. We focus on the varying agreement between modelled and measured VOCs across different species and underscore potential inaccuracies in total and sector-specific emission estimates.

Even though online measurements of biogenic volatile organic compounds (BVOCs) are becoming more common, the use of sorbent tubes is expected to continue because they offer greater spatial coverage and no infrastructure is required for sampling. In this study the sorbent tube sampling method was optimized and evaluated for the determination of BVOCs in gas-phase samples. Tenax TA sorbent tubes were found to be suitable for the quantitative measurements of C10–C15 BVOCs.

The hydroxyl (OH), hydroperoxy (HO2), and organic peroxy (RO2) radicals play important roles in atmospheric chemistry and have significant air quality implications. Here, we compare measurements of OH, HO2, and total peroxy radicals (XO2) made in a remote forest in Michigan, USA, to predictions from a series of chemical models. Lower measured radical concentrations suggest that the models may be missing an important radical sink and overestimating the rate of ozone production in this forest.

This article revolves around the simulation of biogenic secondary organic aerosols in the Landes forest (southwestern France). Several sensitivity cases involving biogenic emission factors, land cover data, anthropogenic emissions, and physical or meteorological parameters were performed and each compared to measurements both in the forest canopy and around the forest. The chemistry behind the formation of these aerosols and their production and transport in the forest canopy is discussed.

Nitrous acid (HONO) is an important source of hydroxyl (OH) radicals, the primary oxidant in the atmosphere. Accurate measurements of HONO are thus important to understand the oxidative capacity of the atmosphere. A new instrument capable of measuring atmospheric nitrous acid (HONO) with high sensitivity is presented, utilizing laser photofragmentation of ambient HONO and subsequent detection of the OH radical fragment.

Sulfuric acid, H2SO4, plays a key role in formation of secondary atmospheric aerosol particles. It is generally accepted that the major atmospheric source of H2SO4 is the reaction of OH radicals with SO2. In this study, importance of an additional H2SO4 source via oxidation of SO2 by stabilized Criegee intermediates was estimated based on measurements at a remote site on Cape Corsica. It was found that the oxidation of SO2 by SCI may be an important source of H2SO4, especially during nighttime.

A multiphasic molecular characterization of oxygenated compounds has been carried out during the ChArMEx field campaign using offline analysis. It leads to the identification of 97 different compounds in the gas and aerosol phases and reveals the important contribution of organic acids to organic aerosol. In addition, comparison between experimental and theoretical partitioning coefficients revealed in most cases a large underestimation by the theory reaching 1 to 7 orders of magnitude.

For the first time, we performed binPMF analysis on the complex mass spectra acquired with the Vocus PTR-TOF in two European pine forests and identified various primary emission sources and secondary oxidation processes of atmospheric organic vapors, i.e., terpenes and their oxidation products, with varying oxidation degrees. Further insights were gained regarding monoterpene and sesquiterpene reactions based on the interpretation results.

MBTCA (3-methyl-1,2,3-butanetricarboxylic acid), a second-generation product of monoterpenes, is one of the most relevant tracer compounds for biogenic secondary organic aerosols (SOAs). Laboratory-generated, micrometer-sized, pure-MBTCA, mono-/di-/trisodium MBTCA salts and MBTCA–NaCl mixture aerosol particles were examined systematically to observe their hygroscopic behavior, and it was also observed that the monosodium MBTCA salt aerosols were formed through a reaction between MBTCA and NaCl.

The OH radical is the primary oxidant in the atmosphere, and measurements of its concentration provide a rigorous test of our understanding of atmospheric chemistry. Previous measurements of OH concentrations in forest environments have shown large discrepancies with model predictions. In this paper, we present measurements of OH in a forest in Indiana, USA, and compare the results to model predictions to test our understanding of this important chemistry.

We deployed the recently developed Vocus PTR-TOF in the French Landes forest during summertime to gain insights into terpene chemistry. In addition to isoprene, monoterpenes, sesquiterpenes, and the low-volatility diterpenes, various terpene reaction products are characterized. Through the analysis of terpene chemistry, we demonstrate the capability of the Vocus PTR-TOF for the detection of oxidized reaction products, highlighting its importance in investigating atmospheric oxidation processes.

In the last scientific assessment report from the LRTAP Convention, it is stated that because non-urban sources are often major contributors to urban pollution, many cities will be unable to meet WHO guideline levels for air pollutants through local action alone. Consequently, it is very important to estimate how much the local and non-local sources contribute to urban pollution in order to design global strategies to reduce the levels of pollutants in European cities.

A large set of volatile organic compound observations was collected for the first time in Istanbul in September 2014. A source–receptor approach has been carried out to apportion emission sources, estimate anthropogenic emissions, and evaluate emission inventories. Unexpectedly, transport was not the most dominant source in this study. Our work stresses the need to better represent VOC emissions in the eastern Mediterranean region with an effort on non-traffic sources and oxygenated VOCs.

Several field campaigns were performed in southern West Africa in the framework of the DACCIWA project with the purpose of measuring a broad range of atmospheric constituents. Our study presents the analysis of a comprehensive dataset which integrates up to 56 species of VOCs measured at different ambient sites and emission sources. Our detailed VOC estimation for Cote d'Ivoire is 3 to 6 times higher than the whole of Europe, transportation being the dominant source of VOCs.

Compounds emitted into the atmosphere are chemically transformed, often leading to new compounds which can affect air pollution and climate. Studying the radicals OH, HO2, and RO2 (organic peroxy radicals) is a crucial activity for assessing how well we understand the rates and products of chemical transformations. In this paper we describe the performance of a new instrument, ECHAMP, for measuring peroxy radicals during its first field deployment.

This work presents time-resolved data of non-methane hydrocarbons (NMHC) from automatic chromatographs, measured over a period of 5 months in the greater Athens area. The measured concentrations are higher relative to other recent studies for the majority of NMHCs. A remarkable day-to-day variability is also observed. The contributions from traffic and residential heating to NMHCs are investigated, as they were the major sources impacting the air quality during the study period.

This study presents the first measurements of ambient methylglyoxal, an important atmospheric α-dicarbonyl, using proton transfer reaction time-of-flight mass spectrometry. These measurements mostly agree with concomitant measurements from a reference technique: the DNPH derivatization technique and high-performance liquid chromatography with UV detection. In addition, a careful investigation of the differences between the two techniques is carried out to explain the disagreements observed.

This work focuses on the study of the sources and fates of BVOCs and new particle formation (NPF) events in the eastern Mediterranean. NPF events were found on 14 out of 20 days of the campaign. NPF occurred at various condensational sinks and both under polluted and clean atmospheric conditions. Analysis of specific NPF periods of the mixed influence type highlighted that BVOC interactions with anthropogenic compounds enhanced nucleation formation and growth of new particles.

In this work, four schemes for the simulation of organic aerosols in the western Mediterranean basin are added to the CHIMERE chemistry–transport model; the resulting simulations are then compared to measurements obtained from ChArMEx. It is concluded that the scheme taking into account the fragmentation and the formation of nonvolatile organic aerosols corresponds better to measurements; the major source of this aerosol in the western Mediterranean is found to be of biogenic origin.

Ground-level ozone is a pollutant that affects both global climate change and regional air quality. Its complex formation chemistry makes the implementation of reduction strategies challenging and needs to be well understood to develop efficient strategies. This publication reports the development of an instrument capable of monitoring the ozone formation rate in the atmosphere. Its reliability was tested in the laboratory and in the field and important recommendations are given for improvement.

This paper describes measurements of the conversion efficiency of several organic peroxy radicals upon reaction with nitric oxide to the hydroperoxy radical, which can interfere with measurements of the latter. This interference could explain some of the discrepancies between measurements and model predictions of the hydroperoxy radical. Previous measurements of the hydroperoxy radical during the Mexico City Metropolitan Area campaign in 2006 are reanalyzed to account for the interference.

Hydroxyl radical reactivity (k(OH)) is closely related to processes that lead to the formation of oxidised, secondary pollutants such as ozone and aerosol. In order to compare the performances of instruments measuring k(OH), experiments were conducted in the simulation chamber SAPHIR. Chemical conditions were chosen either to be representative of the atmosphere or to test potential limitations of instruments. Overall, the results show that instruments are capable of measuring k(OH).

Our paper presents results of hydroxyl radical (OH) reactivity from a field study conducted during summer 2013 in a western Mediterranean coastal site (Corsica, France). Here, the total OH reactivity, measured with the comparative reactivity method, is compared with the summed OH reactivity from the reactive gases measured with a multitude of different technologies. Our results demonstrate the relatively high observed reactivity and the large impact of biogenic compounds.

An intensive field campaign was conducted in March 2015 in the Eastern Mediterranean region, at a background site of Cyprus. We performed a detailed analysis of the chemical composition of air masses in gas and aerosol phase, and we applied a source apportionment analysis in order to identify the various origins of VOCs. The results suggest that VOCs are mainly of biogenic and regional background origins.

The ChArMEx SOP2 field campaign took place from 15 July to 5 August 2013 in the western Mediterranean Basin at Ersa, a remote site in Cape Corse. Exhaustive descriptions of the chemical composition of air masses in gas and aerosol phase were performed. An analysis of these measurements was performed using various source-receptor approaches. This led to the identification of several factors linked to primary sources but also to secondary processes of both biogenic and anthropogenic origin.

The atmospheric chemistry associated with mixing of anthropogenic and natural species was simulated to understand how shade provided by a forest canopy impacts reactions, product distribution, and subsequent phase distribution of the products. This is important to understand, as forested areas downwind of urban areas will be impacted by this phenomenon. It was found that fast transport from below the canopy led to increases in secondary organic aerosol from nitrate radicals above the canopy.

We used detailed speciated measurements of VOCs (volatile organic compounds) to evaluate the spatial heterogeneity of VOC urban emission composition and the consistency of regional and global emission inventories downscaled to Lebanon (EMEP, ACCMIP, and MACCity). The results suggest that systematic and detailed measurements are needed in the eastern Mediterranean Basin in order to better constrain emission inventories.

This article presents ambient air VOC measurements performed in Paris during the MEGAPOLI and FRANCIPOL campaigns (2010). For the first time, we report (O)VOC concentration levels, their temporal variations and their main emission sources. The originality of this study stands in using near-field observations to help strengthen the identification of apportioned sources derived from PMF. An important finding of this work is the high contribution of the wood burning source (50 %) in winter.

This paper describes and presents results from a intercomparison, in an environment rich in NOx (i.e., NO+NO2), of two OH reactivity instruments: one based on the comparative reactivity method, and one based on the pump-probe method. Co-located measurements were made of both ambient air and standard mixtures. Ambient OH reactivity values measured by both instruments were found to be in good agreement for ambient NOx mixing ratios as high as 100 ppbv.

Our manuscript shows results of an intercomparison exercise conducted on two home-built comparative reactivity method (CRM) instruments operating under the same settings for measuring total OH reactivity. Despite the corrections of the raw data sets for instrumental artifacts having different weights on the two CRMs, we found very consistent results for the final processed data of ambient OH reactivity. Furthermore, we present in detail how to validate the instruments and process the raw data.

This study presents the results of an exhaustive characterization of a CRM instrument developed at Mines Douai to measure total OH reactivity in the troposphere. To do so, a suite of laboratory experiments was conducted to assess the different corrections that need to be applied during data processing. The results were then compared to simulations from a 0-D box model, including two different chemical mechanisms, leading to reasonable agreement.

The performance of 20 European laboratories involved in long-term non-methane hydrocarbon (NMHC) measurements was assessed with respect to ACTRIS and GAW data quality objectives. The participants were asked to measure both a 30-component NMHC mixture in nitrogen and whole air. The NMHCs were analysed either by GC-FID or GC-MS. Most systems performed well for the NMHC in nitrogen, whereas in air more scatter was observed. Reasons for this are explained in the paper.

Slow-response analysers may be used here as the relevant frequency ranges depend on measuring height. Tall towers offer a large footprint, amplifying spatial coverage. The presented concept is a valuable bridge between atmospheric and ecosystem communities.

We reviewed 60 sensor networks and 17 related efforts (sensor review papers and data accessibility projects) to better understand the landscape of stationary low-cost gas-phase sensor networks deployed in outdoor environments worldwide. Gaps in monitoring efforts include the availability of gas-phase measurements compared to particulate matter (PM) and geographic coverage gaps (the Global South, rural areas). We conclude with a summary of cross-network unification and quality control efforts.

Chemical ionisation mass spectrometry is used in the atmospheric sciences to measure trace gas concentrations. Neutral gases require charging in inlets before the mass-to-charge ratio of the resulting ions can be analysed. This study uses multiphysics modelling to investigate how the MION2 and Eisele type inlets work and shows the effect of tuning parameters and their current limitations. The findings are helpful for inlet users and are expected to aid in developing improved inlets.

We have developed a portable, optically based instrument that measures NO2. It consumes less than 6 W of power, so it can easily run off a small battery. This instrument has made both balloon and UAV flights. NO2 measurement results compare favorably with other known NO2 instruments. We find this instrument to be stable with repeatable results compared with calibration sources. Material cost to build a single instrument is around USD 4000. This could be lowered with economies of scale.

We have designed and deployed a mid-cost medium-precision CO2 sensor monitoring network in Paris since July 2020. The data are automatically calibrated by a newly implemented data processing system. The accuracies of the mid-cost instruments vary from 1.0 to 2.4 ppm for hourly afternoon measurements. Our model–data analyses highlight prospects for integrating mid-cost instrument data with high-precision measurements to improve fine-scale CO2 emission quantification in urban areas.

This system has been used for direct quantification of point sources and distributed emitters over scales of up to 1 km. The system uses simultaneous measurements of methane and ethane to distinguish between different kinds of natural and human-related emission sources.

Volcanic eruptions emit significant quantities of carbon dioxide (CO2) to the atmosphere. We present a new method for directly determining the CO2 emission from a volcanic eruption on the island of La Palma, Spain, using an unpiloted aerial vehicle (UAV).

Together with the emission rate the isotopic data provide valuable information on the state of volcanic activity and the potential evolution of the eruption.

Findings show that MOSs can provide accurate emission estimates with a 25 % emission rate error and a 9.5 m location error.

This source, and another, is confirmed by driving the instrument downwind of the sites, where concentrations were tens to tens of thousands of times greater than background levels.

We have developed a system that can automatically measure the pump efficiency of the ECC-type ozonesonde. Operational measurement for 13 years by this system revealed that the efficiency fluctuates in each and slightly increases over time. Those can affect the estimation of total ozone amount by up to 4 %. This result indicates that it is necessary to understand the tendency of the pump correction factor of each ozonesonde in order to detect the actual atmospheric change with high accuracy.

Atmospheric variations of helium (He) and CO2 are strongly linked due to the co-release of both gases from natural-gas burning. This implies that atmospheric He measurements may be a potentially powerful tool for verifying reported anthropogenic natural-gas usage. Here, we present the development and initial results of a novel measurement system of atmospheric He that paves the way for establishing a global monitoring network in the future.

This study details a new sampling method for the optical detection of hydrogen chloride (HCl). HCl is an important atmospheric reservoir for chlorine atoms, which can affect nitrogen oxide cycling and the lifetimes of volatile organic compounds and ozone. However, HCl has a high affinity for interacting with surfaces, thereby preventing fast, quantitative measurements. The sampling technique in this study minimizes these surface interactions and provides a high-quality measurement of HCl.

Optical resonators enhance the light path in compact instruments, thereby improving their sensitivity. Determining the established path length in the instrument is a prerequisite for the accurate determination of trace gas concentrations but can be a significant complication in the use of such resonators. Here we show two calibration techniques which are relatively simple and free of consumables but still provide accurate calibrations. This facilitates the use of optical resonators.

It is challenging to make field measurements of stable water isotopes in the Arctic. To this end, we present a modular stable-water-isotope analyzer profiling system. The system operated for a 2-week field campaign on Svalbard during the Arctic winter. We evaluate the system’s performance and analyze any potential impact that the field conditions might have had on the isotopic measurements and the system's ability to resolve isotope gradients in the lowermost layer of the atmosphere.

During a 5-week comparison campaign, we tested two set-ups to measure half hourly ammonia fluxes. The eddy covariance and flux gradient systems showed very similar results when the upwind terrain was both homogeneous and free of obstacles. We discuss the technical performance and practical limitations of both systems. Measurements from these instruments can facilitate the study of processes behind ammonia deposition, an important contributor to eutrophication and acidificationin natural areas.

Vertical observation of volatile organic compounds (VOCs) is essential to study the spatial distribution and evolution patterns of VOCs in the planetary boundary layer (PBL). This paper describes multi-channel whole-air sampling equipment onboard an unmanned aerial vehicle (UAV) for near-continuous VOC vertical observation. Vertical profiles of VOCs and trace gases during the evolution of the PBL in south-western China have been successfully obtained by deploying the newly developed UAV system.

We report in situ measurements of air pollutant concentrations within the planetary boundary layer on board a Zeppelin NT in Germany. We highlight the in-flight evaluation of electrochemical sensors that were installed inside a hatch box located on the bottom of the Zeppelin. Results from this work emphasize the potential of these sensors for other in situ airborne applications, e.g., on board unmanned aerial vehicles (UAVs).

Measurements of atmospheric O2 can help constrain the carbon cycle processes and quantify fossil fuel CO2 emissions; however, measurement of atmospheric O2 is very challenging, and existing analysers are complex systems to build and maintain. We have tested a new O2 analyser (Picarro Inc. G2207-i) in the laboratory and at Weybourne Atmospheric Observatory. We have found that the G2207-i does not perform as well as an existing O2 analyser from Sable Systems Inc.

We present a new, highly sensitive technique for measuring atmospheric ammonia, an important trace gas that is emitted mainly by agriculture. We deployed the instrument on an aircraft during research flights over rural Oklahoma. Due to its fast response, we could analyze correlations with turbulent winds and calculate ammonia emissions from nearby areas at 1 to 2 km resolution. We observed high spatial variability and point sources that are not resolved in the US National Emissions Inventory.

Optical receivers for solar spectral actinic radiation are designed for angle-independent sensitivities within a hemisphere. Remaining imperfections can be compensated for by receiver-specific corrections based on laboratory characterizations and radiative transfer calculations of spectral radiance distributions. The corrections cover a wide range of realistic atmospheric conditions and were applied to ground-based and airborne measurements in a wavelength range 280–660 nm.

This study describes a new technique to measure total gaseous chlorine, which is the sum of gas-phase chlorine-containing chemicals. The method converts any chlorine-containing molecule to hydrogen chloride that can be detected in real time using a cavity ring-down spectrometer. The new method was validated through laboratory experiments, as well as by making measurements of ambient outdoor air and indoor air during cleaning with a chlorine-based cleaner.

Short summary
An automated system for the online ambient measurement of 20 biogenic volatile organic compounds (BVOCs) was successfully developed and optimized. The analytical performance was satisfying for ambient measurements. The first measurements were carried out during the LANDEX field campaign in summer 2017. The 3-week field measurements displayed the excellent performance of the method with respect to providing speciated BVOC concentration values to further investigate atmospheric BVOCs' reactivity.
