Soil is a large pool of carbon storing globally, from 2 to 3 times more carbon than the atmosphere and vegetation. We measure the soil stock change from 2005 to 2019 at the ICOS crop site FR-Gri near Paris. The soil carbon stock decreased by approximately 72 ± 17 g C m-2 yr-1 over the period, resulting in a total loss of around 8% of the initial soil stock. This strong destocking is primarily attributed to a decrease in residue return and organic amendments to the site.

Pastures are an important source of ammonia, a major atmospheric pollutant with manifold environmental impacts. Ammonia is emitted from the decomposition of cattle urine in soils during grazing. We used micrometeorological methods to measure emissions over four grazing seasons. The results show the influence of weather and grassland management on emission processes. Emission factors, used to compile regional inventories, are hugely variable and still very uncertain despite decades of research.

This research aimed at quantifying biogenic volatile organic compounds (BVOCs) emissions by a rapeseed crop field. Such compounds are precursors of atmospheric pollutants. Our study revealed that methanol, a BVOC that is not very reactive in the atmosphere, is by far the most emitted BVOC, while monoterpenes, being highly reactive, were emitted in larger quantities than expected. Our study therefore points out the potentially more significant contribution of croplands to atmospheric pollution.

Volatile organic compounds (VOCs) are precursors of tropospheric pollutants like ozone or aerosols. Emission by agricultural land was still poorly characterized. We report experimental measurements of ecosystem-scale VOC fluxes above a wheat field with a highly sensitive proton transfer mass spectrometer. We report the fluxes of 123 compounds and confirm that methanol is the most emitted VOC by wheat. The second most emitted compound was C6H4O. Around 75 % of the compounds were deposited.

Using WRF-Chem simulations over Greater Paris at resolutions from 900 m to 100 m (LES), we show that horizontal resolution critically shapes urban CO2 plume structure. Mesoscale runs underestimate spatial contrasts by a factor of 2–3, with representativeness errors of 29–61 % (near-surface) and 21–59 % (XCO2). LES improves intra-urban variability and enables more accurate spatial attribution of emissions, a key step toward reliable top-down estimates for city-scale climate mitigation.

This work proposes a new methodology for robust, homogeneous processing of long-term datasets of aerosol mass spectrometer measurements to remedy the challenges posed by the emergence of juxtaposed data processing periods over the years. The results showed a global decrease in PM1 at a semi-urban site in the Paris region between 2011 and 2024, along with a decrease in the frequency of persistent pollution episodes. Finally, it highlights the need for Sulfate source apportionment analysis.

We studied how soil organic carbon stocks changed over 21 years in a Belgian cropland by combining soil sampling, a soil carbon model, and measurements from a flux tower. The soil appeared mostly stable overall, but the flux-tower approach suggested much larger carbon losses than the other methods. Our results show that using several approaches together is important to better understand soil organic carbon changes and to identify farming practices that either build up or reduce soil carbon.

Aromatics compounds emitted in the atmosphere, such as benzene and phenol, contribute to the formation of organic aerosols. This study presents and evaluates an updated description of benzene chemistry, in which the most influential pathways are identified, including one developed in this work. The resulting mechanism reproduces laboratory observation with great accuracy and is reduced for use in large-scale air quality models.

This study explores how city design and buildings affect CO2 levels in the air over Paris. Using a transport model, we tested different urban canopy models to represent the city environment and its influence on air motion. We found that realistic descriptions of urban surfaces are crucial, especially in winter, for accurately showing how CO2 builds up and disperses, leading to better satellite monitoring of city CO2 emissions.

A one-week intensive measurement campaign during the 2022 European heatwave included monitoring of ozone, volatile organic compounds, aerosol chemical composition, and organic tracers to investigate air pollution sources. Results showed that emissions from vegetation and human activities contributed to peaks in ozone and secondary organic aerosol particles. Differences between measurements and model simulations underline the need for better characterization of sources and formation pathways.

Ammonia emissions after field fertilization are a major source of nitrogen losses from agriculture and air pollution, yet cumulative losses remain difficult to predict. Dynamic machine learning models are promising tools. Models tracking emissions over time outperformed those predicting only the final total, reducing errors by nearly 20 %. These advances could improve national emission inventories and support smarter fertilizer management to reduce pollution.

We present radiocarbon (14C)-based fossil fuel CO2 fluxes from relaxed eddy accumulation measurements on tall towers in the cities of Zurich, Paris, and Munich. By separating net CO2 fluxes into fossil and non-fossil components, these data reveal significant and variable contributions from human, plant, and soil respiration, as well as point-source emissions. These unique insights into CO2 flux composition offer crucial information for observation-based validation of urban emission estimates.

Forests release trace gases that influence air and climate. While plants are the main source, soil and leaf litter can also release significant amounts, especially in tropical forests like the Amazon. We measured these fluxes in different forest types and found soil and litter to be active sources and sinks. This can improves climate models by including realistic forest processes, vital for understanding and protecting the Amazon.

Oceans are a natural source of sulfur compounds that can influence climate by forming aerosol particles. During an oceanographic expedition around the Antarctic Peninsula, we measured the emissions of two of these compounds (DMS and methanethiol), their links to seawater microorganisms and particle formation in large enclosures exposed to natural or reduced UV radiation. Our results suggest that UV reduces these emissions and the formation of nanoparticles.

The chemical composition of organic particles in the Amazon rainforest was investigated to understand how biogenic and human emissions influence the atmosphere in this unique ecosystem. Seasonal patterns were found where wet seasons were dominated by biogenic compounds from natural sources while dry seasons showed increased fire-related pollutants. These findings reveal how emissions, fires and long-range transport affect atmospheric chemistry, with implications for climate models.

The Saclay observatory, 20 km southwest of Paris, monitored greenhouse and reactive gases, as well as aerosols, over 10 years to assess the impact of urban emissions. By comparing downwind and background conditions, the study revealed significant reductions in pollutants linked to traffic: -35.6 % for CO, -52.3 % for NOₓ, -56.7 % for eBC, and -15 % for CO2. These trends align with emission decrease estimates from AIRPARIF inventories over the same period.

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

This study presents direct flux measurements in tall towers using existing slow-response analysers and adding 3D sonic anemometers. This way, we can significantly improve greenhouse gas monitoring with little extra instrumental effort. 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.

This study presents the development of a bottom-up inventory of urban tree biogenic emissions. Emissions are computed for each tree based on their location and characteristics and are integrated in the regional air quality model WRF-CHIMERE. The impact of these biogenic emissions on air quality is quantified for June–July 2022. Over Paris city, urban trees increase the concentrations of particulate organic matter by 4.6 %, of PM2.5 by 0.6 %, and of ozone by 1.0 % on average over 2 months.

Using eddy-covariance systems deployed in three cities, we aimed to elucidate the sources of discrepancies in flux estimations from different software packages. One crucial finding is the impact of low-frequency spectral loss corrections on tall-tower flux estimations. Our findings emphasize the significance of a standardized measurement setup and consistent postprocessing configurations in minimizing the systematic flux uncertainty resulting from the usage of different software packages.

Aerosol particles in the atmosphere play a key role in climate change and air pollution. A large number of aerosol particles are formed from the oxidation of volatile organic compounds (VOCs and secondary organic aerosols – SOA). An important field campaign was organized on Réunion in March–April 2019 to understand the formation of SOA in a tropical atmosphere mostly influenced by VOCs emitted by forest and in the presence of clouds. This work synthesizes the results of this campaign.

By combining field measurements, simulations and recent chamber experiments, we investigate new particle formation (NPF) and growth in the Po Valley, where both haze and frequent NPF occur. Our results show that sulfuric acid, ammonia and amines are the dominant NPF precursors there. A high NPF rate and a lower condensation sink lead to a greater survival probability for newly formed particles, highlighting the importance of gas-to-particle conversion for aerosol concentrations.

Anaerobic digestion is used for biogas production. The resulting digestates may be associated with different crop performances and N losses compared to undigested animal effluents. We monitored N flows during a three-year field experiment with different fertilizations based on cattle effluents, digestates, or mineral fertilizers. Digestates were effective N fertilizer but required attention to NH3 volatilization. We identified no additional risks of N2O emissions with digestates.

This research aimed at quantifying biogenic volatile organic compounds (BVOCs) emissions by a rapeseed crop field. Such compounds are precursors of atmospheric pollutants. Our study revealed that methanol, a BVOC that is not very reactive in the atmosphere, is by far the most emitted BVOC, while monoterpenes, being highly reactive, were emitted in larger quantities than expected. Our study therefore points out the potentially more significant contribution of croplands to atmospheric pollution.

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.

Long-term measurements of volatile organic compounds (VOCs) have been set up to better characterize the atmospheric chemistry at the SIRTA national facility (Paris area, France). Results obtained from the first 2 years (2020–2021) confirm the importance of local sources for short-lived compounds and the role played by meteorology and air mass origins in the long-term analysis of VOCs. They also point to a substantial influence of anthropogenic on the monoterpene loadings.

The oceans are both sources and sinks for trace gases important for atmospheric chemistry and marine ecology. Here, we quantified selected trace gases (including the biological metabolites dissolved dimethyl sulfide, methanethiol and isoprene) along a 2500 km transect from the North Atlantic to the Arctic Ocean. In the context of phytoplankton and bacterial communities, our study suggests that methanethiol (rarely measured before) might substantially influence ocean–atmosphere cycling.

Chiral chemodiversity plays a critical role in biochemical processes such as insect and plant communication. Here we report on the measurement of chiral-specified secondary organic aerosol in the Amazon rainforest. The results show that the chiral ratio is mainly determined by large-scale emission processes. Characteristic emissions of chiral aerosol precursors from different forest ecosystems can thus provide large-scale information on different biogenic sources via chiral particle analysis.

Volatile organic compounds (VOCs) are precursors of tropospheric pollutants like ozone or aerosols. Emission by agricultural land was still poorly characterized. We report experimental measurements of ecosystem-scale VOC fluxes above a wheat field with a highly sensitive proton transfer mass spectrometer. We report the fluxes of 123 compounds and confirm that methanol is the most emitted VOC by wheat. The second most emitted compound was C6H4O. Around 75 % of the compounds were deposited.

The COVID-19 outbreak led to lockdowns at national scales in spring 2020. Large cuts in emissions occurred, but the quantitative assessment of their role from observations is hindered by weather and interannual variability. That is why we developed an innovative methodology in order to best characterize the impact of lockdown on atmospheric chemistry. We find that a local decrease in traffic-related pollutants triggered a decrease of secondary aerosols and an increase in ozone.

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.

Short summary
This research aimed at quantifying biogenic volatile organic compounds (BVOCs) emissions by a rapeseed crop field. Such compounds are precursors of atmospheric pollutants. Our study revealed that methanol, a BVOC that is not very reactive in the atmosphere, is by far the most emitted BVOC, while monoterpenes, being highly reactive, were emitted in larger quantities than expected. Our study therefore points out the potentially more significant contribution of croplands to atmospheric pollution.
