Atmospheric aerosol particles act as a key modulator of Earth's climate. New particle formation (NPF) from condensable gas molecules is the fundamental source of most atmospheric particles. The ...

Tiny particles such as ice crystals or ash particles tend to oscillate as they settle through the atmosphere. In their experiments, the scientists were able to track non-spherical particles of size ...

Air pollution is one of the most critical environmental challenges in modern society. The World Health Organization has recently lowered the recommended annual concentration of PM 2.5 from 10 μg/m 3 ...

A recent study has uncovered compelling evidence suggesting that the climate effects of new particles in urban areas have been significantly underestimated. Particles play a crucial role in climate ...

Atmospheric aerosols and clouds play important roles in determining the Earth’s climate. Trace gases and aerosols, constitute only a tiny fraction of the atmospheric mass, however they interfere with ...

A new study published in Advances in Atmospheric Sciences has shed light on a previously overlooked but common atmospheric phenomenon: the transition zone (TZ) where clouds and aerosols blend together ...
