      Hall, Chris; Hansen, Georg; Sigernes, Fred; 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 ...
