Researchers have explored how chemical reactions in clouds can influence the global climate. They found that isoprene, the dominant non-methane organic compound emitted into the atmosphere, can ...

A conflict-driven reroute of international ships exposed how dramatically cleaner fuel reduces cloud formation.

Oxidized organic molecules originating from the Amazon rainforest are crucial components contributing to the formation of aerosol particles in the tropical free troposphere, according to a new study ...

Nga Lee “Sally” Ng leads a new study investigating the formation and properties of secondary organic aerosol from the nitrate radical oxidation of two common monoterpenes, compounds found in many ...

To climate scientists, clouds are powerful, pillowy paradoxes: They can simultaneously reflect away the sun’s heat but also trap it in the atmosphere; they can be products of warming temperatures but ...

Solid aerosols can change how clouds form in the Arctic. And, as the Arctic loses ice, researchers expect to see more of these unique particles formed from oceanic emissions combined with ammonia from ...

Scientists have sussed out a new source for the seeds of clouds. When the stratospheric layer of Earth’s atmosphere dips a toe into the underlying troposphere, the resulting chemical mixture becomes a ...

Urban landscapes and man-made aerosols have the potential to accelerate the formation of hail storms, according to a recent study by the U.S. Department of Energy’s Pacific Northwest National ...

Researchers at the Paul Scherrer Institute PSI have studied for the first time how chemical reactions in clouds can influence the global climate. They found that isoprene, the dominant non-methane ...
