Newly discovered chemical mechanisms behind aerosol nucleation could improve climate models
Two new chemical mechanisms behind cloud formation have been discovered in experiments at Cern. The mechanisms, which involve the interaction of iodine oxoacid and sulfuric acid vapours to nucleate water droplets, provide new insights into cloud formation above oceans and in the polar regions and will help to improve the accuracy of important climate change models.
