    • Characteristics of fragmented aurora-like emissions (FAEs) observed on Svalbard 

      Dreyer, Joshua; Partamies, Noora; Whiter, Daniel; Ellingsen, Pål Gunnar; Baddeley, Lisa; Buchert, Stephan C. (Journal article; Peer reviewed, 2021)
      This study analyses the observations of a new type of small-scale aurora-like feature, which is further referred to as fragmented aurora-like emission(s) (FAEs). An all-sky camera captured these FAEs on three separate ...

    • Cutoff Latitudes of Solar Proton Events Measured by GPS Satellites 

      van Hazendonk, Charlotte Maartje; Heino, Erkka Petteri; Jiggens, Piers T.A.; Taylor, Matthew G.G.T.; Partamies, Noora; Mulders, Hjalmar C. J. (Journal article; Peer reviewed, 2022)
      Solar energetic particles (SEPs), one of the main causes of particle radiation in interplanetary space, can disrupt radio communication, induce spacecraft failures and change the heating and cooling rates in the atmosphere ...

    • Electron precipitation characteristics during isolated, compound, and multi-night substorm events 

      Partamies, Noora; Tesema, Fasil; Bland, Emma; Heino, Erkka; Tyssøy, Hilde Nesse; Kallelid, Erlend Salte (Journal article; Peer reviewed, 2021)
      A set of 24 isolated, 46 compound, and 36 multi-night substorm events from the years 2008–2013 have been analysed in this study. Isolated substorm events are defined as single expansion–recovery phase pairs, compound ...

    • 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 ...

    • Observations of precipitation energies during different types of pulsating aurora 

      Kebede, Fasil Tesema; Partamies, Noora; Tyssøy, Hilde Nesse; McKay, Derek (Journal article; Peer reviewed, 2020)
      Pulsating aurora (PsA) is a diffuse type of aurora with different structures switching on and off with a period of a few seconds. It is often associated with energetic electron precipitation (>10 keV) resulting in the ...

    • Overview of the Rocket Experiment for NeutralUpwelling Sounding Rocket 2 (RENU2) 

      Lessard, Marc R.; Fritz, Bruce; Sadler, Brent; Cohen, Ian J.; Kenward, David; Godbole, Niharika; Clemmons, James H.; Hecht, James H.; Lynch, Kristina A.; Harrington, Meghan; Roberts, Thomas M.; Hysell, David; Crowley, Geoff; Sigernes, Fred; Syrjäsuo, Mikko; Ellingsen, Pål Gunnar; Partamies, Noora; Moen, Jøran Idar; Clausen, Lasse Boy Novock; Oksavik, Kjellmar; Yeoman, Timothy (Journal article; Peer reviewed, 2020)
      The Rocket Experiment for Neutral Upwelling 2 (RENU2) rocket was launched on 13 December 2015 at 07:34 UT. The payload transited the cusp region during a neutral upwelling event, supported by a comprehensive set of onboard ...

    • The Predictive Capabilities of the Auroral Electrojet Index for Medium Energy Electron Precipitation 

      Tyssøy, Hilde Nesse; Partamies, Noora; Babu, Eldho Midhun; Smith-Johnsen, Christine; Salice, Josephine Alessandra (Journal article; Peer reviewed, 2021)
      The chemical imprint of the energetic electron precipitation on the atmosphere is now acknowledged as a part of the natural forcing of the climate system. It has, however, been questioned to which degree current proxies ...

    • Scholarship of teaching and learning: Learning diary as a field work report 

      Partamies, Noora (UPED-skrift;, Working paper, 2016)

    • 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, ...

    • Space and atmospheric physics on Svalbard: a case for continued incoherent scatter radar measurements under the cusp and in the polar cap boundary region 

      Baddeley, Lisa; Lorentzen, Dag Arne; Haaland, Stein Egil; Heino, Erkka Petteri; Mann, Ingrid Brigitte; Miloch, Wojciech Jacek; Oksavik, Kjellmar; Partamies, Noora; Spicher, Andres; Vierinen, Juha-Pekka (Journal article; Peer reviewed, 2023)
      Incoherent scatter radars (ISRs) represent the only instrument (both ground and space based) capable of making high temporal and spatial resolution measurements of multiple atmospheric parameters—such as densities, ...

    • Types of pulsating aurora: Comparison of model and EISCAT electron density observations 

      Tesema, Fasil; Partamies, Noora; Whiter, Daniel K.; Ogawa, Yasunobu (Journal article; Peer reviewed, 2022)
      Energetic particle precipitation associated with pulsating aurora (PsA) can reach down to lower mesospheric altitudes and deplete ozone. It is well documented that pulsating aurora is a common phenomenon during substorm ...
