Fig. 14From: A review of the SCOSTEP’s 5-year scientific program VarSITI—Variability of the Sun and Its Terrestrial ImpactMagnitude of the short-term EEP effects on mesospheric ozone. a–c O3 anomalies (%) for selected EEP events in the Northern hemisphere and in the Southern hemisphere derived from GOMOS (a), SABER (b), and MLS (c) observations. Black dashed lines: EEP event start end end; red dashed lines: SPE event start end; black numbers: daily mean electron count rates (ECRs); red numbers: 410 MeV pfu. d–i Superposed epoch analysis for EEP events with daily ECR 4150 (counts s1) showing ozone anomalies (%) and ECR (black lines) in the Northern hemisphere (d, f, h) and in the Southern hemisphere (e, g, i). White numbers: O3 loss at different altitudes (taken from Andersson et al. 2014)Back to article page
