Despite the development of increasingly complex and sophisticated Earth System Models, many challenges remain in understanding how the atmosphere may evolve through the 21st century. New forcing agents not traditionally accounted for by models are entering the atmosphere, and representing natural emissions is hampered by a lack of observations and process-based understanding. I will highlight recent work carried out within my group on modelling atmospheric chemistry and climate that addresses some of these challenges. First, I will discuss our recent progress in simulating sources and emissions of dimethylsulfide (DMS) with the UKESM1 -AMIP model. DMS is a key contributor to sulfate aerosol and cloud condensation nuclei over the remote Southern Ocean. I will also show preliminary results from a modelling study into rocket launch emissions and their impacts on stratospheric ozone. Finally, I will discuss airborne microplastics, which are now understood to be ubiquitous in the atmosphere. As well as being damaging to ecosystems and harmful to human health when inhaled, my group’s research shows that airborne microplastics may make a minor contribution to global radiative forcing, which is expected to grow in future.
