abstract = {We explore the impact of different stratospheric sulfur
injection strategies to counter greenhouse gas induced
warming on total column ozone (TCO), including high and low
altitude injections at four latitudes, equatorial
injections, and using a configuration with higher vertical
resolution, based on a state-of-the-art Earth system model.
The experiments maintain global surface temperatures at 2020
conditions, while following the unmitigated future scenario.
Within the first 10 years of the injection, we find an
abrupt deepening of the Antarctic ozone hole by $8\%–20\%$
and changes up to $5\%$ for other regions and seasons. The
ozone hole recovery is delayed by ∼25 to over 55 years,
with the fastest recovery for low-altitude injections and
slowest for equatorial injections. Mid to high-latitude TCO
increases by $15\%$ in Northern Hemisphere winter and spring
between 2010–2019 and 2080–2089 due to both increasing
greenhouse gases and increasing sulfur injections.
Implications for ecosystems need to be investigated.},
