We collected 6 years of flux measurements at two southern taiga peatland ecosystems, namely a paludified spruce forest and ombrotrophic bog located in the same landscape in western Russia, which showed that the interannual variability in the environmental conditions affect CO2 ecosystem–atmosphere exchange differently in forest and non-forest peatlands. We observed that an anomalously warm winter and spring led to increasing CO2 uptake at the paludified forest (more than at the bog).

We summarize results during the last 5 years in the northern Eurasian region, especially from Russia, and introduce recent observations of the air quality in the urban environments in China. Although the scientific knowledge in these regions has increased, there are still gaps in our understanding of large-scale climate–Earth surface interactions and feedbacks. This arises from limitations in research infrastructures and integrative data analyses, hindering a comprehensive system 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.

Northern ecosystems exchange climate-relevant trace gases with the atmosphere, including volatile organic compounds (VOCs). We measured VOC fluxes from a subarctic permafrost-free fen and its adjacent lake in northern Sweden. The graminoid-dominated fen emitted mainly isoprene during the peak of the growing season, with a pronounced response to increasing temperatures stronger than assumed by biogenic emission models. The lake was a sink of acetone and acetaldehyde during both periods measured.

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.

Climate change has caused glaciers in the Arctic to shrink, uncovering new soils. We used field measurements to study the exchange of a group of gases involved in ozone destruction, called halocarbons, between these new soils and the atmosphere. We found that mats of cyanobacteria, early colonisers of soils, are linked to a larger-than-expected exchange of halocarbons with the atmosphere. We also found that gases which are commonly thought to be marine in origin were released from these soils.

Biogenic volatile organic compounds (BVOCs) are important components of the atmosphere due to their contribution to atmospheric chemistry and biogeochemical cycles. In this study, we report major BVOCs, e.g. isoprene and total monoterpene flux measurements with a proton transfer reaction time-of-flight mass spectrometer (PTR-TOF-MS) using the eddy covariance (EC) method at a primary rainforest in eastern Amazonia. We used the measured data to evaluate the MEGAN2.1 model for the emission site.

There are several widely grown tree species whose BVOC emission potentials are still unknown. Studies over the Amazon rainforest have reported presence of terrestrial dimethyl sulfide sources. Here, we show that mahogany, which is grown widely in several regions of the world, is a high emitter of dimethyl sulfide and monoterpenes. With future land use and land cover changes promoting plantations of this tree for economic purposes, its impact on air quality could be quite significant.

The work reported here is the first, the most comprehensive molecularly based study of atmospheric deposition of plants. Plants disperse spores, pollen, and fragments into the atmosphere. The emitted plant particles return to the pedosphere by sedimentation (dry deposition) and/or by precipitation (wet deposition), comprising part of the Earth's cycling of substances. This study reports plant assemblages in dry and wet atmospheric deposits collected together at the same sampling point.

Biomass burning is one of the largest sources of atmospheric pollutants worldwide. This paper presents an up-to-date compilation of emission factors for over 120 trace gas and aerosol species from the different forms of open vegetation fires and domestic biofuel use, based on an analysis of over 370 published studies. Using these emission factors and current global burning activity data, the annual emissions of important species released by the various types of biomass burning are estimated.

For a long time sea-salt particles were considered the only types of particles that drive sea-fog formation but recently iodine oxide particles released from kelp have been identified as a source. There are no previous field studies to provide a direct timeline link between molecular iodine release, particle formation and sea-fog formation. The present observations from Cork Harbour provide such a link. A stabilizing mechanism enhancing distribution of iodine in the troposphere is suggested.

The contribution of soil carbonyl sulfate (COS) flux is probably the major limitation to the application of COS as a novel tracer of canopy-scale CO2 uptake. We provide new, field-based high-resolution results on the spatial and temporal variations in soil COS flux, its relationships to CO2 exchange and the key factors influencing it. We furthermore provide the only study, to our knowledge, that validate the surface dynamic chamber approach, increasingly used, with soil concentration profiles.

VOCs play a key role in atmospheric chemistry. Emission and deposition on soil have been suggested as important sources and sinks of atmospheric trace gases. The exchange characteristics and heterogeneous chemistry of VOCs on soil, however, are not well understood. We used a newly designed differential coated-wall flow tube system to investigate the long-term variability of bidirectional air–soil exchange of 13 VOCs at ambient air conditions of an urban background site in Beijing.

Wildfire smoke in July 2015 had a significant impact on air quality, radiation, and energy budgets across British Columbia. With lighter smoke, a wetland and forested site showed enhanced photosynthetic activity (taking in carbon dioxide). However, with dense smoke the forested site became a strong source. These results suggest that smoke during the growing season potentially plays an important role in the carbon budget, and this effect will likely increase as climate changes.

Understanding the impact of agricultural activities on the atmosphere requires more measurements of inorganic trace gases and associated aerosol counterparts. This research presents 1 month of measurements above agricultural grassland during a period of fertiliser application. It was found that emissions of the important trace gases ammonia and nitrous acid peaked after fertiliser use and that the velocity at which the measured aerosols were deposited was dependent upon their size.

Most soils consume carbonyl sulfide (COS) and CO due to microbial uptake, but whether boreal forest soils act like this is uncertain. We measured growing season soil COS and CO fluxes in a Finnish pine forest. The soil behaved as a consistent and relatively invariant sink of COS and CO. Uptake rates of COS and CO decrease with soil moisture due to diffusion limitation and increase with respiration because of microbial control. Using COS to infer photosynthesis is not affected by soil COS flux.

A unique long-term dataset of NH3 and NH4+ data from the NAMN is used to assess spatial, seasonal and long-term variability across the UK. NH3 is spatially variable, with distinct temporal profiles according to source types. NH4+ is spatially smoother, with peak concentrations in spring from long-range transport. Decrease in NH3 is smaller than emissions, but NH4+ decreased faster than NH3, due to a shift from stable (NH4)2SO4 to semi-volatile NH4NO3, increasing the atmospheric lifetime of NH3.

We developed a theory on the seasonal behaviour of photosynthesis in natural conditions and tested the theory with intensive measurements. Light, temperature, water vapor and CO2 concentration explained the daily variation in photosynthesis, and the physiological state of the photosynthetic machinery explained the annual pattern of photosynthesis. The theory explained about 95 % of the variance of photosynthesis measured with chambers in the field in northern Finland.

Alkenes emanate from both natural and anthropogenic sources and can contribute to atmospheric ozone production. This study measured
lightalkene (ethene, propene and butene) fluxes from a ponderosa pine forest using a novel relaxed eddy accumulation method, revealing much larger emissions than previously estimated and accounting for a significant fraction of OH reactivity. Emissions have a diurnal cycle related to sunlight and temperature, and the forest canopy appears to be the source.

Besides the well-known large impact on agriculture and water resources, drought is associated with significant adverse effects on air quality. Drought-induced degradation of air quality is largely due to natural processes, offsetting the effort of anthropogenic emission reduction during the past decades. Such adverse impacts should be included in modeling processes under current and future climate for mitigation policy.

Arctic temperatures have risen faster than the global average, causing the depth of melting of the frozen ground to increase. Previously frozen organic carbon, once exposed to air, water, and microbes, is turned into carbon dioxide and methane, both of which are important greenhouse gases. Due to the large and varied surface area of the Arctic and the difficulty of making measurements there we use a low flying aircraft (<25 m) to measure the amount of methane released from different regions.

We investigated the BVOC emissions variations of Quercus Pubescens, under natural and amplified drought, in situ, in order to determine the dependency to light and/or temperature of these emissions. Our results showed that all BVOC emissions were reduced with amplified drought.
Moreover, we highlighted two dependences: (i) light and temperature and (ii) light and temperature during the day and to temperature during the night. These results can be useful to enhance emission models.

The role of volatile organic compounds (VOCs) in plant interactions with the atmosphere is investigated through field observations of branch-level VOC exchange in a New England forest. The data reveal previously unknown sources and sinks of oxygenated VOCs. The emission of methyl ethyl ketone is linked to uptake of methyl vinyl ketone, suggesting the possibility of within-leaf isoprene oxidation. Bidirectional fluxes of some VOCs are also reported, including for benzaldehyde for the first time.

We present spring and summer VOC emission rate measurements from Norway spruce using an in situ gas chromatograph. Monoterpene and C4–C10 aldehyde emission rates reached maxima in July. SQT emissions increased at the end of July and in August SQT were the most abundant group. The MT emission pattern varied a lot from tree to tree and therefore emission fluxes on canopy level should be conducted for more representative measurements. However, leaf level measurements produce more reliable SQT data.

The role that soil, foliage, and atmospheric dynamics have on surface OCS exchange in a Mediterranean forest ecosystem in southern France (O3HP) was investigated in June of 2012 and 2013 with essentially a top-down approach. Atmospheric data suggest that the site is appropriate for estimating GPP directly from eddy covariance measurements of OCS fluxes, but it is less adequate for scaling NEE to GPP from observations of vertical gradients of OCS relative to CO2 during the daytime.

We performed field measurements and controlled field experiments to examine the flux, temporal variation and influencing factors of air–surface Hg(0) exchange at a high-altitude and remote site in the central Qinghai–Tibet Plateau. We found that the environmental conditions greatly influenced the air–surface Hg dynamics. Our results have important implications for the Hg biogeochemical cycle in the soils of Qinghai–Tibet Plateau under rapid climate warming and environmental change.

Accelerated N emissions in China may lead to an imbalance of atmospheric nutrient inputs in various ecosystems. Our assessment of P and N deposition in China's forests showed relatively high rates of P deposition, but they were accompanied by even much higher N deposition, resulting in high N : P deposition ratios. P and N deposition both showed a power-law increase with closer distance to the nearest large cities. Our results suggest an anthropogenic imbalance of regional N and P cycling.

Plants produce volatile compounds (BVOCs) that have a major role in atmospheric chemistry. Our aim was to see if terpenes, a key group of BVOCs, can be found on surfaces of pine needles and, if so, how they compare with the emissions of the same tree. Both emissions and wax extracts were clearly dominated by monoterpenes, but there were also differences in the emission and wax spectra. The results support the existence of BVOCs on needle surfaces, with possible implications for air chemistry.

Volatile organic compounds (VOCs) represent a large source of reactive carbon in the atmosphere and hence have a significant impact on air quality. It is therefore important that we can accurately quantify their emission. In this paper we use three methods to determine the fluxes of reactive VOCs from a woodland canopy. We show that two different canopy-scale measurement methods give good agreement, whereas estimates based on leaf-level-based emission underestimate isoprene fluxes.

In this study, high light-dependent isoprene emissions were observed from mature V. guianensis leaves in the central Amazon. As predicted by energetic models, isoprene emission increased nonlinearly with net photosynthesis. High leaf temperatures resulted in the classic uncoupling of net photosynthesis from isoprene emissions. Finally, leaf phenology differentially controlled methanol and isoprene emissions.

We study the potentially contrasting effects of enhanced ecosystem CO2 release in response to warmer temperatures vs. emissions of biogenic volatile organic compounds and their formation of secondary organic aerosol through a combination of measurements and modelling at a remote location in Eastern Siberia. The study aims to highlight the number of potentially opposing processes and complex interactions between vegetation physiology, soil processes and trace-gas exchanges in the climate system.

This manuscript introduces a conceptual design of a global, hierarchical observation network which provides tools and increased understanding to tackle the inter-connected environmental and societal challenges that we will face in the coming decades. Each ecosystem type on the globe has its own characteristic features that need to be taken into consideration. The hierarchical network is able to tackle problems related to large spatial scales, heterogeneity of ecosystems and their complexity.

Methanol is the second most abundant volatile organic compound in the troposphere and plays a significant role in atmospheric chemistry. While there is consensus about the dominant role of plants as the major source and the reaction with OH as the major sink, global methanol budgets diverge considerably in terms of source/sink estimates. Here we present micrometeorological methanol flux data from eight sites in order to provide a first cross-site synthesis of the terrestrial methanol exchange.

Next-generation sequencing revealed the existence of diverse community of bacteria in the Arctic samples with many originating from distinct ecological environments. The observed varied range in ice nucleation of cultivable bacteria and in all of the melted samples further revealed the existence of the heterogeneous pool of bacteria. Changes in the microbial pool and its impact on the freezing and melting process may potentially lead to changing the Arctic environment and thus global climate.

What role do forests play in determining the concentration (and composition) of climate-relevant aerosol particles? This study seeks to address two aspects of this question. Firstly, we document high in-canopy removal of recently formed particles. Then we show evidence that growth rates of particles are a function of soil water availability via a reduction in canopy emissions of gases responsible for particle growth to climate-relevant sizes during drought conditions.
