Received: 25 October 2010 – Published in Atmos. Chem. Phys. Discuss.: 04 January 2011 Abstract. 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 the stratosphere. If one is to exploit
the potential of tropopause height as a metric for climate change at high
latitude and elsewhere, it is imperative to observe and understand the
processes which establish the tropopause – an understanding to which this
