Motivation:
Volcanic supereruptions are the largest explosive eruptions in modern earth history. In the past 100,000 years, 4 supereruptions have been recorded so far. Not much is known about how they impact the atmosphere and the environment.
Data:
- Loc Chocoyos 15 N supereruption (Kutterolf et al 2016)
- CESM2(WACCM6) model data (Brenna et al 2020)
- Ice core data and other available proxy records
Method:
- Analysis of the Quasi-Biennial Oscillation, Southern Annual Mode, sulphate deposition over the polar ice caps, as well as ozone and UV (Brenna et al 2019/2020/2021; Toohey et al 2013; Sigl et al 2014).
