LEO‐DOS Absorbed Dose Observations During the May 2024 Geomagnetic Superstorm
Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract The Low‐Earth Orbit Space Radiation Dosimeter (LEO‐DOS) onboard Next‐Generation Satellite II (NEXTSat‐2) measured absorbed dose rate variations during the May 2024 geomagnetic superstorm. The observations show deep storm‐time penetration of solar energetic particle (SEP) spanning L ≈ 2–10, a pronounced enhancement near L ≈ 3 consistent with ...
