The 2018 Outstanding Student Poster and PICO (OSPP) Award is awarded to Hans Brenna for the poster/PICO entitled:

Global ozone depletion and increase of UV radiation caused by pre-industrial tropical volcanic eruptions (Brenna, H.; Kutterolf, S.; Krüger, K.)

Hans Brenna is a PhD candidate at the University of Oslo (Norway). He researches the impact of large volcanic eruptions on atmospheric chemistry and climate using chemistry climate models.
Using data gathered in the field as model input, the poster focuses on simulations of a large volcanic eruption from the Central American Volcanic Arc injecting large amounts of sulfur and halogen gases into the tropical stratosphere. The volcanic eruption results in a global decrease in ozone, taking a decade to recover, and a large increase in surface ultraviolet radiation, with potential surface impacts.
