My research focuses on the global climate impacts of nucleation, primarily through changes in cloud condensation nuclei and cloud processes. The research will be based on development and application of the UKESM Earth System Model and the Global Model of Aerosol Processes (GLOMAP). I will actively participate in the CLOUD experiments conducted at CERN which study the effect of cosmic rays on new particle formation in the atmosphere. The aim will be to quantify the effect of nucleation and growth rates (from CLOUD measurements) on the global aerosol system in pre-industrial and present-day conditions and to evaluate the model against ambient observations and assess the uncertainty. The model results will be used to refine the definition of chemical environments to be studied in the CLOUD chamber. The goal is to quantify and assess the global climate impact of the nucleation experiments conducted at CERN using climate models.
