Tracking air volumes for assessing the effect of urban aerosols on convective precipitation: a multi-member modeling study

Abstract. Urban emissions impact aerosol–cloud interactions and thereby modify precipitation patterns, yet whether realistic emission perturbations from a mid-sized European city produce detectable effects above internal meteorological variability in a high-background aerosol env...

Morphological and Size‐Dependent Enrichment of Endotoxins in Coastal Spray Aerosols: Implications for Regional Respiratory Health Risks

Abstract Sea spray aerosols (SSA) transport bioactive substances that affect the Earth's environmental and climate system. We investigated the enrichment of endotoxins (LPS), characterized their influence on the SSA morphologies, and evaluated the respiratory tract deposition. LP...

Observation-based analysis of horizontally oriented ice crystals using dual-angle polarization lidar and cloud Doppler radar in Beijing

Abstract. Ice crystal orientation strongly influences cloud radiative properties and remote sensing retrievals, but long-term, high-resolution quantitative observations remain scarce. This study presents comprehensive case studies and statistical analyses of horizontally oriented...

Exploring the hydrogen abstraction pathway in HOM formation from α -pinene photooxidation systems under varying NO conditions

Abstract. Highly oxygenated organic molecules (HOM) are formed via autoxidation during ⚫OH-initiated oxidation of α-pinene. We investigated the relative contributions of OH-addition and hydrogen (H)-abstraction to HOM formation from α-pinene photooxidation under varying nitrogen...
