    • Multistatic Specular Meteor Radar Network in Peru: System Description and Initial Results 

      Chau, Jorge L.; Urco, Miguel; Vierinen, Juha; Harding, Brian; Clahsen, Matthias; Pfeffer, Nico; Kuyeng, Karim; Milla, Marco; Erickson, Philip J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-10)
      The mesosphere and lower thermosphere (MLT) region is dominated globally by dynamics at various scales: planetary waves, tides, gravity waves, and stratified turbulence. The latter two can coexist and be significant at horizontal scales less than 500 km, scales that are difficult to measure. This study presents a recently deployed multistatic specular meteor radar system, SIMONe Peru, which can be ...

    • Tropopause height at 78 degrees N 16 degrees E: average seasonal variation 2007-2010 

      Hall, Chris; Hansen, Georg Heinrich; Sigernes, F; Kuyeng, Karim (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      We present a seasonal climatology of tropopause altitude for 78° N 16° E derived from observations 2007–2010 by the SOUSY VHF radar on Svalbard. The spring minimum occurs one month later than that of surface air temperature and instead coincides with the maximum in ozone column density. This confirms similar studies based on radiosonde measurements in the arctic and demonstrates downward control by ...
