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 ...

The formation of new aerosol particles is a complicated process. Researchers have only recently started to understand this process on a molecular level after instruments able to detect nanometer-scale ...

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 ...

Anthropogenic ammonia (NH3) emissions have risen sharply in recent decades, largely due to intensified agricultural activity.

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 ...

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 ...

Rerouted shipping during Red Sea conflicts accidentally created a massive real-world experiment, letting scientists study how ...

Reducing man-made emissions could decrease aerosols that come from plants, according to new simulations by scientists from the Environmental Protection Agency. Atmospheric chemists have known for a ...

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 ...
