Northern hemisphere stratospheric ozone depletion caused by solar proton events: the role of the polar vortex
Sign Up to like & getrecommendations! Published in 2018 at "Geophysical Research Letters"
DOI: 10.1002/2017gl075966
Abstract: Ozonesonde data from four sites are analyzed in relation to 191 solar protons events (SPEs) from 1989-2016. Analysis shows ozone depletion (~10-35 km altitude) commencing following the SPEs. Seasonally-corrected ozone data demonstrate that depletions occur… read more here.
