The tiny particles are effectively invisible to most instruments but may play a role in stratospheric chemistry ...

Based on our testing and health experts' analysis, we recommend the Shark HP232 for effectively removing fine particles ...

Global measurements and model calculations show that the complex relationship between the chemistry and climate impact of aerosol particles can be successfully captured by a simple formula. The extent ...

Atmospheric physicist Adele Igel received a US Department of Energy grant to study the role of tiny particles or aerosols in thunderstorms. Thousands of thunderstorms occur around the globe on any ...

As experts investigate why warming is accelerating, a new study suggests that changes in ship aerosols may be a contributing ...

Cleaner air is making marine clouds dimmer and oceans warmer, revealing a climate trade-off called the "clean air paradox." ...

Aerosols refer to fine solid or liquid particles suspended in the atmosphere, where they reside typically for days to weeks before falling to the ground or being washed out by rain or snow. They arise ...

New high-altitude measurements have revealed a hidden population of extremely small, organic-rich aerosol particles in the lower stratosphere. The findings suggest that these ultrafine aerosols, ...

Small aerosol particles spewed while people breathe, talk and sing may contain more coronavirus than larger moisture droplets do. And the coronavirus may be evolving to spread more easily through the ...

The impact of atmospheric aerosols on clouds and climate may be different than previously thought. The impact of atmospheric aerosols on clouds and climate may be different than previously thought.
