Impacts of enhanced new-particle growth events above urban roughness sublayer on cloud condensation nuclei
New-particle formation (NPF) events are frequently observed in urban environments, yet their occurrence and climate effects are still in question. We analyzed the physical and chemical processes during the new-particle growth (NPG) at the ground and 260 m based on measurements on the 325-m tower in the megacity of Beijing, China. Our results provide evidence for stronger NPG aloft in city, mainly due to the higher production of sulfuric acid alof…
Black-carbon-induced regime transition of boundary layer development strongly amplifies severe haze
Black-carbon (BC) aerosol can strongly influence planetary boundary layer (PBL) development and thus severe haze formation, but its distinct role compared with scattering aerosols is not yet fully understood. Here, combining numerical simulation and field observation, we found a “tipping point,” where the daily maximum PBL height decreases abruptly when exceeding a critical threshold of aerosol optical depth (AOD), due to a BC-induced decoupling …
The impact of particulate pollution control on aerosol hygroscopicity and CCN activity in North China
Air quality has greatly improved in China owing to the strict control policy enforced during the last decade. This study investigated the impact of particulate pollution control on aerosol hygroscopicity and cloud condensation nuclei (CCN) activity in North China based on several data sources. The mass concentration of particles with an aerodynamic diameter smaller than 2.5 μ m (PM 2.5 ) decreased by one third from the summer of 2014 to the summe…
The ChinaHighPM10 dataset
Respirable particles with aerodynamic diameters ≤ 10 μm (PM10) have important impacts on the atmospheric environment and human health. Available PM10 datasets have coarse spatial resolutions, limiting their applications, especially at the city level. A tree-based ensemble learning model, which accounts for spatiotemporal information (i.e., space-time extremely randomized trees, denoted as the STET model), is designed to estimate near-surface PM10…
Reconstructing 1-km-resolution high-quality PM2.5 data records from 2000 to 2018 in China
Contrasting Trends of Surface PM2.5, O3, and NO2 and Their Relationships with Meteorological Parameters in Typical Coastal and Inland Cities in the Yangtze River Delta
The contrasting trends of surface particulate matter (PM 2.5 ), ozone (O 3 ), and nitrogen dioxide (NO 2 ) and their relationships with meteorological parameters from 2015 to 2019 were investigated in the coastal city of Shanghai (SH) and the inland city of Hefei (HF), located in the Yangtze River Delta (YRD). In both cities, PM 2.5 declined substantially, while O 3 and NO 2 showed peak values during 2017 when the most frequent extreme high-tempe…
Improved 1 km resolution PM 2.5 estimates across China using enhanced space–time extremely randomized trees
Fine particulate matter with aerodynamic diameters ≤2.5 μm (PM2.5) has adverse effects on human health and the atmospheric environment. The estimation of surface PM2.5 concentrations has made intensive use of satellite-derived aerosol products. However, it has been a great challenge to obtain high-quality and high-resolution PM2.5 data from both ground and satellite observations, which is essential to monitor air pollution over small-scale areas …
Dryland climate change
Drylands are home to more than 38% of the world's population and are one of the most sensitive areas to climate change and human activities. This review describes recent progress in dryland climate change research. Recent findings indicate that the long‐term trend of the aridity index (AI) is mainly attributable to increased greenhouse gas emissions, while anthropogenic aerosols exert small effects but alter its attributions. Atmosphere‐land inte…
