This project investigates simulations of tropical volcanic eruptions using the UM-UKCA aerosol-climate model with an explicit representation of the QBO. Simulations include eruptions emitting 60 Tg of SO2 (i.e., 1815 Mt. Tambora-magnitude) and 15 Tg of SO2 (i.e., 1991 Mt. Pinatubo-magnitude) initiated at the equator during two different QBO states. The dataset includes variables to understand the QBO response to a tropical volcanic eruption and the physical and dynamical drivers of the response.
