Short summary
Recent studies have shown that chloric acid (HClO3, CA) is prevalent in the Arctic boundary layer. However, the mechanism of CA-based nucleation is unclear. We provide molecular-level evidence that CA-dimethylamine (DMA) nucleation may not effectively contribute to Arctic new particle formation (NPF). The proposed CA-DMA nucleation mechanism may help us to deeply understand marine NPF events in the Arctic boundary layer.

Nitrogen dioxide is a common air pollutant that varies strongly across space and time, yet consistent global information has been limited. We developed a new global dataset that describes daily nitrogen dioxide levels from 2005 to 2023 by combining satellite observations, weather data, and ground measurements using artificial intelligence. The dataset reveals long-term changes and regional patterns and provides a reliable resource for future air quality research.

Terpinolene is an isomeride of limonene, with a high secondary organic aerosol (SOA) yield. The comparative analysis of OH-initiated (daytime) and NO3-driven (nocturnal) terpinolene oxidation mechanism, highlighted the formation of nitrogen-containing oxygenated organic molecules (OOMs), would be conducive to molecular structures identification of OOMs in atmospheric monitoring and atmospheric chemical model refinement.

By integrating field measurements with an interpretable ensemble machine learning framework, we comprehensively identified key driving factors of nitro-aromatic compounds (NACs), demonstrated complex interrelationships, and quantified their contributions across different locations. This work provides a reliable modeling approach for recognizing causes of NAC pollution, enhances our understanding of variations of atmospheric NACs, and highlights the necessity of strengthening emission controls.

Rainwater samples collected at the summit of Mount Tai were analyzed for ice-nucleating particles (INPs). Our findings revealed that INP concentrations peaked in spring, driven predominantly by long-range transport of dust aerosols. Mineral dust contributed 43.6 % of annual INPs, with its contribution rising sharply to 71.7 % in spring. Satellite observations further revealed that the long-range transport of dust in spring promotes large-scale cloud formation over the NCP region.

This study established a bottom-up approach that employs real-time traffic flows and interpolation to obtain a spatially continuous on-road vehicle emission mapping for the main urban area of Jinan. The diurnal variation, spatial distribution, and emission hotspots were analyzed with clustering and hotspot analysis, showing unique fine-scale variation characteristics of on-road vehicle emissions. Future scenario analysis demonstrates remarkable benefits of electrification on emission reduction.

India is facing a severe air pollution crisis that poses significant health risks, particularly from PM2.5 and O3. Our study reveals rising levels of both pollutants from 1995 to 2014, leading to increased premature mortality. While anthropogenic emissions play a significant role, biomass burning also impacts air quality, in particular seasons and regions in India. This study underscores the urgent need for localized policies to protect public health amid escalating environmental challenges.

We developed a novel transformer framework to bridge the sparse surface monitoring for inferring ozone–NOx–VOC–aerosol sensitivity and their urban–nonurban discrepancies at a finer scale with implications for improving our understanding of ozone variations. The change in urban–rural disparities in ozone was dominated by PM2.5 from 2019 to 2020. An aerosol-inhibited regime on top of the two traditional NOx- and VOC-limited regimes was identified in Jiaodong Peninsula, Shandong, China.

Field observations were conducted at the summit of Changbai Mountain in northeast Asia. The cumulative number concentration of ice-nucleating particles (INPs) varied from 1.6 × 10−3 to 78.3 L−1 over the temperature range of −5.5 to −29.0 ℃. Biological INPs (bio-INPs) accounted for the majority of INPs, and the proportion exceeded 90% above −13.0 ℃. Planetary boundary layer height, valley breezes, and long-distance transport of air mass influence the abundance of bio-INPs.

Nitrous acid (HONO) is vital for atmospheric oxidation. In research at Mount Lao, China, models revealed a significant unidentified marine HONO source. Overlooking this could skew our understanding of air quality and climate change. This finding emphasizes HONO’s importance in the coastal atmosphere, uncovering previously unnoticed interactions.

Short summary
This study examines how perchloric acid (HClO₄) promotes atmospheric new particle formation. Computational simulations reveal that dimethylamine (DMA) greatly enhances this process—far more effectively than ammonia or sulfuric acid, even at substantially lower concentrations. The DMA–HClO₄ interaction thus represents a previously overlooked source of marine aerosols, offering new insight into polar climate change.
