Description:

The Southern Hemisphere Antarctic stratosphere experienced two noteworthy events in 2015: a signi ﬁcant injection of sulfur from the Calbuco volcanic eruption in Chile in April and a record-large Antarctic ozone hole in October and November. Here we quantify Calbuco ’si nﬂuence on stratospheric ozone depletion in austral spring 2015 using observations and an Earth system model. We analyze ozonesondes, aswell as data from the Microwave Limb Sounder. We employ the Community Earth System Model, version 1, with the Whole Atmosphere Community Climate Model (WACCM) in a speci ﬁed dynamics setup, which includes calculations of volcanic effects. The Cloud-Aerosol Lidar with Orthogonal Polarization data indicateenhanced volcanic liquid sulfate 532 nm backscatter values as far poleward as 68°S during October and November (in broad agreement with WACCM). Comparison of the location of the enhanced aerosols to
