Atmospheric Drag, Occultation 'N' Ionospheric Scintillation (ADONIS) mission proposal: Alpbach Summer School 2013 team orange
Hettrich, Sebastian; Kempf, Yann; Perakis, Nikolaos; Górski, Jędrzej; Edl, Martina; Urbář, Jaroslav; Dósa, Melinda; Gini, Francesco; Roberts, Owen W.; Schindler, Stefan; Schemmer, Maximilian; Steenari, David; Joldžić, Nina; Ødegaard, Linn-Kristine Glesnes; Sarria, David; Volwerk, Martin; Praks, Jaan (Peer reviewed; Journal article, 2015)The Atmospheric Drag, Occultation ‘N’ Ionospheric Scintillation mission (ADONIS) studies the dynamics of the terrestrial thermosphere and ionosphere in dependency of solar events over a full solar cycle in Low Earth Orbit ... -
Direct and indirect electron precipitation effect on nitric oxide in the polar middle atmosphere, using a full-range energy spectrum
Smith-Johnsen, Christine; Tyssøy, Hilde Nesse; Hendrickx, Koen; Orsolini, Yvan; Kishore Kumar, Grandhi; Ødegaard, Linn-Kristine Glesnes; Sandanger, Marit Irene; Stordal, Frode; Megner, Linda (Peer reviewed; Journal article, 2017)In April 2010, a coronal mass ejection and a corotating interaction region on the Sun resulted in an energetic electron precipitation event in the Earth’s atmosphere. We investigate direct and indirect nitric oxide (NO) ... -
Energetic electron precipitation in weak to moderate corotating interaction region-driven storms
Ødegaard, Linn-Kristine Glesnes; Tyssøy, Hilde Nesse; Søraas, Finn; Stadnes, Johan; Sandanger, Marit Irene (Peer reviewed; Journal article, 2017-03)High-energy electron precipitation from the radiation belts can penetrate deep into the mesosphere and increase the production rate of NOx and HOx, which in turn will reduce ozone in catalytic processes. The mechanisms for ... -
Energetic Electron Precipitation into the Middle Atmosphere – Constructing the Loss Cone Fluxes from MEPED POES
Tyssøy, Hilde Nesse; Sandanger, Marit Irene; Stadsnes, Johan; Zawedde, Annet Eva; Ødegaard, Linn-Kristine Glesnes; Åsnes, Arne (Peer reviewed; Journal article, 2016-06)The impact of energetic electron precipitation (EEP) on the chemistry of the middle atmosphere (50–90 km) is still an outstanding question as accurate quantification of EEP is lacking due to instrumental challenges and ... -
Energetic particle precipitation into the middle atmosphere - optimization and applications of the NOAA POES MEPED data
Ødegaard, Linn-Kristine Glesnes (Doctoral thesis, 2016-09-09)This thesis has been a part of the research in the Q3 group of the Birkeland Centre for Space Science, which focus on the larger question "What are the effects of particle precipitation on the atmosphere?". An ... -
In-flight calibration of NOAA POES proton detectors - Derivation of the MEPED correction factors
Sandanger, Marit Irene; Ødegaard, Linn-Kristine Glesnes; Tyssøy, Hilde Nesse; Stadsnes, Johan; Søraas, Finn; Oksavik, Kjellmar; Aarsnes, Kjell (Peer reviewed; Journal article, 2015-11-25)The MEPED instruments on board the NOAA POES and MetOp satellites have been continuously measuring energetic particles in the magnetosphere since 1978. However, degradation of the proton detectors over time leads to an ... -
Nitric Oxide Response to the April 2010 Electron Precipitation Event: Using WACCM and WACCM‐D With and Without Medium‐Energy Electrons
Smith-Johnsen, Christine; Marsh, Daniel R.; Orsolini, Yvan; Tyssøy, Hilde Nesse; Hendrickx, Koen; Sandanger, Marit Irene J.; Ødegaard, Linn-Kristine Glesnes; Stordal, Frode (Peer reviewed; Journal article, 2018-06-07)Energetic electrons from the magnetosphere deposit their energy in the atmosphere and lead to production of nitric oxide (NO) in the mesosphere and lower thermosphere. We study the atmospheric NO response to a geomagnetic ... -
Recalibration of the MEPED Proton Detectors Onboard NOAA POES Satellites
Ødegaard, Linn-Kristine Glesnes (Master thesis, 2013-07-04)In this thesis we have calibrated energetic proton data from the solid state detectors of the MEPED instrument onboard the satellites NOAA 15, 16, 17, 18, and MetOp 02. All these satellites are part of the NOAA/POES program, ... -
Space Weather impact on the degradation of NOAA POES MEPED proton detectors
Ødegaard, Linn-Kristine Glesnes; Tyssøy, Hilde Nesse; Sandanger, Marit Irene; Stadsnes, Johan; Søraas, Finn (Peer reviewed; Journal article, 2016-06-07)The Medium Energy Proton and Electron Detector (MEPED) on board the National Oceanic and Atmospheric Administration Polar Orbiting Environmental Satellites (NOAA POES) is known to degrade with time. In recent years a lot ...
