CLOUD-MOTION is a network of PhD students at 10 institutions across Europe investigating the role of aerosol nucleation and ice nucleation for atmospheric aerosol, clouds and climate. The focus of investigations is on aerosol nucleation and growth in pristine environments (tropical free troposphere and unpolluted marine environments) and aerosol nucleation and growth in the anthropogenically polluted atmosphere (urban environments). The major research activity of the network will be three sets of joint experiments carried out at the CLOUD aerosol chamber at CERN to which all students contribute. At the CLOUD chamber nucleation experiments are performed at an unprecedented level of precision and completeness using highly innovative instrumentation. In Leeds, CLOUD-MOTION supports two PhD students, one working on global climate model simulations and the other using high-resolution models to investigate how aerosol nucleation affects clouds.
