BBC Inside Science
Paulo Fessia, deputy head of the upgrade project, shows us what they're doing and why. In one of the cavernous halls on the site, Antti Onnela explains what the machinery is used for when it's not smashing particles together; understanding the formation of clouds. With Eva Sommer, Run Coordinator of the project, we learn how clouds are born from aerosol particles in a specialised chamber and how this informs climate models.
