Anthropogenic organic aerosols are carbon-containing particles emitted by humans into the air, which are classified as ...

2010). Their variability is due to the numerous sources and varying formation mechanisms (Figure 1). Aerosol particles are either emitted directly to the atmosphere (primary aerosols) or produced ...

At the CERN laboratory in Switzerland, particle physicist Jasper Kirkby studies the link between aerosols, cosmic rays and cloud formation, using the data to inform climate models. “It’s ...

Understanding the mechanisms through which aerosol particles form and grow is critical for constraining a planet’s energy budget, however, our knowledge of the key processes governing particle ...

Nucleation and gas-to-particle conversion of material are examples of secondary aerosol formation processes. In contrast, aerosol material emitted to the atmosphere directly is known as primary.

The Atmospherically Relevant Chemistry and Aerosol Box Model (ARCA) is used for simulating atmospheric chemistry, the formation of stable molecular clusters and the time evolution of aerosol particles ...

Professor Friedrich’s research, for example, focuses on investigating kinematic and microphysical processes relevant for cloud formation. Professor Toohey’s research addresses the role of trace gases ...

Aerosols also have an indirect effect as condensation nuclei for droplet formation. Depending on particle properties, they can influence cloud formation and characteristics (brightness, lifetime).

Human-made aerosols, they found, were contributing to cloud formation, increasing the planet's reflectivity, and causing a modest cooling. Some scientists even suggested that air pollution ...

An unplanned experiment takes scientists closer to solving a long-standing mystery: To what extent, if any, have ...
