In-depth understanding of near-ground vertical and temporal photochemical ozone (O3) formation is crucial for mitigating O3 pollution. By utilizing a self-built vertical observation system, a direct net photochemical O3 production rate detection system, and an observation-based model, we have diagnosed the vertical distributions and formation mechanism of net photochemical O3 production rates and sensitivity in Pearl River Delta region, one of the most O3 polluted area in China.

By employing an improved net photochemical ozone production rate (NPOPR) detection system based on the dual-channel reaction chamber technique, we measured the net photochemical ozone production rate in the Pearl River Delta in China. The photochemical ozone formation mechanisms in the reaction and reference chambers were investigated using the observation-data-constrained box model, which helped us to validate the NPOPR detection system and understand photochemical ozone formation mechanism.

We designed a new reactor for measurements of OH reactivity (i.e., OH radical loss frequency) based on the comparative reactivity method under
high-NOx conditions, such as in cities. We performed a series of laboratory tests to evaluate the new reactor. The new reactor was used in the field and performed well in measuring OH reactivity in air influenced by upwind cities.

Reactive oxygen species (ROS) are believed to contribute to the adverse health effects of aerosols. We measured particle-bound ROS (PB-ROS) with an online instrument in two distinct environments, i.e., Beijing (China) and Bern (Switzerland). In both cities these exogenic ROS are predominantly related to secondary organic aerosol (SOA). PB-ROS content in SOA from various anthropogenic emission sources tested in the laboratory was comparable to that in the ambient measurements.

We thoroughly studied the reactive oxygen species (ROS) generation potential of particulate wood combustion emissions, from different combustion technologies, fuel types, operation methods, combustion regimes and phases. ROS from automatically operated combustion devices under optimal conditions were much lower than those from manually operated appliances. We examined the impact of atmospheric aging on ROS content in SOA and determined the controlling parameters, by using an online ROS analyzer.

Reactive oxygen species (ROS) in the particle phase may induce oxidative stress in the human lungs upon inhalation. Here we present and thoroughly characterize a modified online and offline ROS analyzer. Selected model organic compounds were tested and potential interferences from gas-phase and matrix effects of particulate constituents were evaluated. ROS measurements of filter samples revealed the rapid decay of a substantial ROS fraction, supporting the application of online measurements.

Offline analyses of the hygroscopicity and composition of atmospheric aerosols are complementary to online analyses in view of the applicability to broader sizes, specific compound groups, and investigations at remote sites. This offline study characterized the composition of water-soluble matter in aerosols and their humidity-dependent hygroscopicity on Okinawa, a receptor site of East Asian outflow. Further, comparison with online analyses showed the appropriateness of the offline method.

The temperature and acidity dependence of yields and chemical compositions of the α-pinene ozonolysis SOA were systematically investigated using a newly developed compact chamber system. Increases in SOA yields were observed with the decrease in temperature and under acidic seed conditions. The differences in chemical compositions between acidic and neutral seed conditions were characterized and explained from the viewpoints of acid-catalyzed reactions. Some organosulfates were newly detected.

The relationship between black carbon (BC) and carbon monoxide (CO) can differ by the different structure of fuel consumption. By investigating the representativeness of the BC and CO emission inventory for real-world comparison with reliable observations, this study suggested that accurate CO emissions should be preferentially investigated to enhance the accuracy of the BC emission rate over East Asia.

The volatility distributions of secondary organic aerosol (SOA) formed from the photooxidation of 1,3,5-trimethylbenzene were investigated by composition, heating, and dilution measurements. Fresh SOA, formed from 1,3,5-trimethylbenzene, included low-volatility compounds with < 1 μg m–3 saturation concentrations, which are not assumed to exist in fresh SOA particles in the standard volatility basis-set approach. Improvements in the organic aerosol model will be necessary.

The volatility distribution of α-pinene secondary organic aerosols (SOAs) was evaluated with a wide range of techniques, including offline chemical analysis and dilution- and heat-induced evaporation. Compounds less volatile than semi-volatile products, i.e., highly oxygenated molecules and dimers, were identified as products, and the SOA evaporation with equilibration timescales of 24–46 min after dilution were observed.

We have deployed a single particle soot photometer (SP2) to characterize black carbon (BC) aerosols near industrial sources in Japan in the early summer of 2014 and at a remote island in the spring of 2015. The observed changes in the SP2-derived size distributions and mixing state of BC-containing particles with air mass transport are connected to meteorological variability (transport pathways and air mass histories) in spring in east Asia.

Field measurements for trace-level chemical species in the gas and particulate phases were conducted at a rural site in westernmost Japan to better understand formation of secondary pollutants in transboundary air. A comparison of photochemical ages estimated by chemical clock with ozone concentrations or fractions of carboxylate in organic aerosol showed proportional relationships, and their slopes were 3.48 × 10−7 ppbv molecule−1 cm3 h−1 and 1.05 × 10−9 molecule−1 cm3 h−1, respectively.

Detailed understandings of the light absorption property of black carbon (BC) particles and its relation to the mixing state and morphology are important. In this study, the enhancement of light absorption of BC due to coating (lensing effect) in a well-aged air mass was observed at an East Asian outflow site in Japan using a photoacoustic spectrometer, and its relation with mixing state and morphology of individual particles was examined based on transmission electron microscope analyses.

Estimating the characteristics of atmospheric P deposition is critical to understanding the biogeochemical P cycle. Here we chose a typical urban–rural transition to monitor the dry and wet P depositions for 2 years. We found that atmospheric dry P deposition was the primary form of total P deposition, and P deposition could be affected by both meteorological factors and land-use types. Findings provide proper management of land use, which may help mitigate the pollution caused by P deposition.

The present study examines the role of tropical cyclones in the enhancement of tropospheric ozone. The most significant and new observation reported is the increase in the upper-tropospheric ozone by 20–50 ppbv, which has extended down to the middle and lower troposphere. The descent rate of enhanced ozone layer during the passage of tropical cyclone is 0.8–1 km day−1. Enhancement of surface ozone concentration by ~ 10 ppbv in the daytime and 10–15 ppbv at night-time is observed.

We show the first mercury profile measurements over Europe since 1996. Besides gaseous elemental mercury (GEM) and total gaseous mercury (TGM), the gases CO, SO2, NOx, and O3 were measured from aboard a research aircraft over four European locations. Compared to the boundary layer, the concentration of GEM and TGM in the free troposphere was 10–30% lower. Inside the individual layers no vertical gradient was apparent. Combined with CARIBIC data, a unique profile from 0.4 to 10.5 km is provided.

Short summary
HO2 radicals play key roles in tropospheric chemistry, their levels in ambient air not yet fully explained by sophisticated models. Here we measured HO2 uptake kinetics onto ambient aerosols in real time using a self-built online system and investigated the impacting factors on such processes by coupling with other instrumentations. The role of the HO2 uptake process in O3 formation is also discussed. Results give useful information for coordinated control of aerosol and ozone pollutants.
