Observations of Electron Precipitation During Pulsating Aurora and Its Chemical Impact
Kebede, Fasil Tesema; Partamies, Noora; Tyssøy, Hilde Nesse; Kero, Antti; Smith-Johnsen, Christine (Journal article; Peer reviewed, 2020)Pulsating auroras (PsAs) are low‐intensity diffuse aurora, which switch on and off with a quasiperiodic oscillation period from a few seconds to ∼10 s. They are predominantly observed after magnetic midnight, during the ... -
Simulated seasonal impact on middle atmospheric ozone from high-energy electron precipitation related to pulsating aurorae
Verronen, Pekka T.; Kero, Antti; Partamies, Noora; Szelag, Monika E.; Oyama, Shin-Ichiro; Miyoshi, Yoshizumi; Turunen, Esa (Journal article; Peer reviewed, 2021)Recent simulation studies have provided evidence that a pulsating aurora (PsA) associated with high-energy electron precipitation is having a clear local impact on ozone chemistry in the polar middle mesosphere. However, ...
