Estimating Vascular Age to Evaluate the Association Between Aging and Cardiovascular Disease

open access: yesAging Cell, Volume 25, Issue 5, May 2026.
The normalized cardiovascular age acceleration (NCAA) index is estimated using the Klemera‐Doubal method (KDM) based on annual physical examination records at Tongji Hospital in Wuhan, China. Vascular function‐based (basic) NCAA shows different associations with cardiometabolic risk factors by age and sex.

Geostationary Air Quality Monitoring Substantiates Column NO2 as a Better O3 Formation Regime Indicator in China

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract China has become a global hotspot of ozone (O3) pollution, and understanding O3 formation regime is crucial for air quality management. Satellite‐observed formaldehyde‐to‐nitrogen‐dioxide ratio (HCHO/NO2, FNR) has long been demonstrated as an efficient way to infer O3 formation regime.

Significant Contribution of Gaseous Organic Nitrogen to Wet and Dry Nitrogen Deposition: Evidence From Year‐Long Monitoring in Coastal Hong Kong

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Atmospheric nitrogen (N) deposition critically affects ecosystem dynamics and carbon cycling, yet organic N (ON) remains under‐monitored relative to inorganic N (IN), limiting constraints on global N budgets and impacts. We conducted year‐long dry and wet deposition measurements of water‐soluble ON (WSON) and IN at a coastal Hong Kong site ...

Could Narrow Bipolar Events Serve as a Distinct Lightning Proxy for Revealing Overshooting Thunderclouds Development?

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Narrow bipolar events (NBEs) are often generated in overshooting thunderclouds (OT) penetrating the stratosphere. However, how and under what conditions OT produces such discharges remains unclear. With 3‐year lightning observations and simultaneous cloud top brightness temperature measurements over South China, we developed a more accurate OT
