20-year study reveals significant ozone depletion due to decades of solar proton events
A comprehensive study led by Grigoriy Doronin, using data from NASA’s Aura MLS and NOAA’s SWPC, examined mesospheric ozone depletion due to solar proton events (SPEs) over the past two decades. The study, which ran from 2004 to 2024, demonstrated the considerable impact of high-energy protons from the Sun on ozone levels, indicating notable changes in depletion patterns across the northern and southern hemispheres.
