  4. 2. Radar Signatures of Auroral Plasma Instability

    Author : Nicola Schlatter; Nickolay Ivchenko; Anja Stromme; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ionosphere; Particle Precipitation; Instability; Plasma Turbulence; Fysik; Physics;

    Abstract : Incoherent scatter radars are powerful ground based instruments for ionospheric measurements. By analysis of the Doppler shifted backscatter spectrum, containing the signature of electrostatic plasma waves, plasma bulk properties are estimated. READ MORE

  6. 4. The impact of mesospheric dynamics and chemistry on key chemical species: 20 years of Odin/SMR satellite observations

    Author : Francesco Grieco; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; mesosphere; energetic particle precipitation; H2O; NO; atmospheric solar tides; microwave limb sounding; CO;

    Abstract : Coupling mechanisms between different atmospheric layers are such that changes in middle atmospheric dynamics and composition have an effect on what happens at lower altitudes and on the climate. There is therefore a need to extend climate models to include higher altitudes and to perform measurements of the middle atmosphere. READ MORE

  7. 5. Solar Forcing of Nitric Oxide in the Upper Atmosphere

    Author : Koen Hendrickx; Linda Megner; Jörg Gumbel; Bernd Funke; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nitric oxide; NO; mesosphere; lower thermosphere; MLT; energetic particle precipitation; EPP; medium energy electrons; MEE; SOFIE; SNOE; WACCM; POES; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : The forcing of the Sun on Earth's atmosphere manifests itself via solar radiation and energetic particle precipitation (EPP), which variations are most noticeable in the upper regions of the atmosphere. A key species in the lower thermosphere, which is influenced by solar forcing, is nitric oxide (NO). READ MORE
