1 WHAT PROBLEMS WERE ADDRESSED? Final year medical students possess a wealth of knowledge but lack experience and confidence putting theory into clinical practice. This impacts readiness for on-call duties during training for new doctors.1 Simulation of on-call duties is a novel approach to improve clinical preparedness.1 However, we are not aware of programmes being able to deliver this for large cohorts. 2 WHAT WAS TRIED? We conducted a 3-hour on-call simulation for final year medical students.

Model simulations presented in this paper suggest that transport processes associated with the summer monsoons bring increased abundances of hydrochloric acid into contact with liquid sulfate aerosols in the cold tropical lowermost stratosphere, leading to heterogeneous chemical activation of chlorine species.
