Stratospheric ozone changes from explosive tropical volcanoes: Modelling and ice core constraints
International audience • The tropical volcanic eruption in the model shows that the sign of the ozone change is highly sensitive to stratospheric chlorine amounts. • δ 15 N(NO − 3) (a proxy for surface ultraviolet radiation) from the Samalas eruption is obscured by inter-annual variability in the ic...
