Short summary
Aerosol size distribution is important for understanding the climate impacts of aerosols; however, it is difficult to validate modeled size distributions. This study introduces a new method that compares physical variables, such as cloud condensation nuclei and light extinction coefficients, derived from size distribution measurements. Using data from Tsukuba, Japan, the method shows that the new model (v2.0) improves predictions of aerosol size distribution by about 17% compared to v1.0.

Using a numerical model and observations of surface concentration and depositions, the current study provides quantitative assessments of resuspension, transport, and deposition of radio-Cs in eastern Japan in 2013, which was once deposited to the ground surface after the Fukushima nuclear accident. The areal mean resuspension rate of radio-Cs from the ground to the air is estimated as 0.96 % per year, which is equivalent to 1–10 % of the decreasing rate of the ambient gamma dose in Fukushima.

This study summarizes continuous measurements of surface air concentrations and deposition of radiocesium in Fukushima city over 8 years after the Fukushima nuclear accident. The concentration in the city was high in winter and low in summer (inverse of the forest area). The decreasing trends were much faster in the earlier stage, probably because dissolved cesium discharged faster from the local environment. Biotite might play a key role in circulation of particulate cesium in Fukushima city.

This study presents the detailed analysis of acid deposition over southeast Asia based on the Model Inter-Comparison Study for Asia (MICS-Asia) phase III. Simulated wet deposition is evaluated with observation data from the Acid Deposition Monitoring Network in East Asia (EANET). The difficulties of models to capture observations are related to the model performance on precipitation. The precipitation-adjusted approach was applied, and the distribution of wet deposition was successfully revised.

To address the lack of continuous ground-based CO2 measurements in the Indo-Gangetic Plain, we started ground-based measurements of atmospheric CO2 concentrations, for the very first time at Sonipat within the IGP. Based on these measurements, we examined the seasonal and diurnal patterns of atmospheric CO2. We found that the interplay of anthropogenic emissions, biospheric fluxes, and prevailing meteorology contributes to the observed high seasonal and diurnal variability of atmospheric CO2.

Black carbon and CO are important to climate change. EMeRGe airborne observation can identify the suitability of emission inventories used in the CMAQv5.0.2 model for Asian polluted regions. GFEDv4.1s is suitable for fire emissions. Anthropogenic BC and CO emissions from the Philippines (REASv2.1) are insufficient. The estimated Chinese emissions in 2018 are 0.65±0.25 TgBC, 166±65 TgCO, and 12.4±4.8 PgCO2, suggesting a reduction and increment for China's BC and CO emissions in the HTAPv2.2z inventory.

We have collected stratospheric air samples using balloon-borne cryogenic samplers over Japan since 1985 and analyzed them for δ13CO2. δ13CO2 has decreased through time in the mid-stratosphere with an average rate of change of −0.026 ± 0.001 ‰ yr−1. We found that stratospheric δ13CO2 variations are governed by airborne production of 13C-depleted CO2 by CH4 oxidation, gravitational separation, and propagation of the decreasing tropospheric δ13CO2 trend into the stratosphere.

This study estimated regional and sectoral emission contributions to the unprecedented surge of atmospheric methane for 2020–2022. The methane is the second most important greenhouse gas, and its emissions reduction is urgently required to mitigate global warming. Numerical modeling-based estimates with three different sets of atmospheric observations consistently suggested large contributions of biogenic emissions from South Asia and Southeast Asia to the surge of atmospheric methane.

Our study compares model CO2 with aircraft and OCO-2 data to identify transport model errors to better policy-related flux estimation. The model align better with aircraft data than satellite data, especially over oceans, but struggles near the surface due to inaccurate CO2 estimates. Over the Amazon and Asian megacities, differences arise from limited measurements and coarse model resolution, highlighting the need for improved monitoring and higher-resolution data to capture emissions better.

A method evaluating techniques for carbon neutrality, such as carbon capture and storage (CCS), is important. This study presents a method to evaluate CO2 emissions from a cement plant based on atmospheric O2 and CO2 measurements. The method will also be useful for evaluating CO2 capture from flue gas at CCS plants, since the plants remove CO2 from the atmosphere without causing any O2 changes, just as cement plants do, differing only in the direction of CO2 exchange with the atmosphere.

This work examines the near-ground aerosol–weather relationship from 7-month continuous lidar and weather observations in Chiba, Japan. Optical parameters from lidar data are compared with weather parameters to understand and quantify the aerosol–weather relationship and how these optical parameters are affected by the weather and season. The results provide insights into analyzing optical properties of radioactive aerosols when the lidar system is continuously operated in a radioactive area.

The atmospheric O2 / N2 ratio and CO2 concentration over the western North Pacific are presented. We found significant modification of the seasonal APO cycle in the middle troposphere due to the interhemispheric mixing of air. APO driven by the net marine biological activities indicated annual sea–air O2 flux during El Niño. Terrestrial biospheric and oceanic CO2 uptakes during 2012–2019 were estimated to be 1.8 and 2.8 Pg C a−1, respectively.

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.

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.

Short summary
Air pollution in Delhi during the post-monsoon period is severe, and association with intensive crop residue burning (CRB) over Punjab state has attracted attention. However, the relationship has been unclear as the CRB emissions conventionally derived from satellites were underestimated due to clouds or thick smoke/haze over the region. We evaluated the impact of CRB on PM2.5 to be about 50 %, based on a combination of numerical modeling and an observation network using low-cost sensors we installed.
