Isoprene emitted by tropical forests may provide a globally important source of aerosol particles that influence clouds, according to a new study by the CLOUD collaboration at CERN

The results imply that climate models are underestimating the formation rates of aerosol particles

FLOTUS is a new addition to the CLOUD experiment at CERN. By accelerating the oxidation of organic vapours before injecting them into the CLOUD chamber, FLOTUS allows more complex atmospheric phenomena to be studied

The resultant particles quickly spread around the globe, potentially influencing Earth’s climate on an intercontinental scale

The CLOUD collaboration has revealed a new mechanism that drives winter smog episodes in cities

A new run of the CLOUD experiment examines the direct effect of cosmic rays on clouds

Measurements of the production rates of atmospheric aerosol particles by CERN’s CLOUD experiment put global climate projections on more solid ground

CERN’s CLOUD experiment points to a cloudier pre-industrial climate in two Nature papers published today

From cloud chambers to 3D animations, physicists use a host of ingenious techniques to reveal subatomic particles too tiny to see

TEDed and particle physicist at CERN Jasper Kirkby come together to animate the effect of clouds on the Earth’s climate
