    <description>
      A NOAA Dynasonde was installed by the Max Planck institute at
      its Ionospheric Heating facility near Troms&#248; in 1980. During its
      first decade, the instrument was used intermittently to monitor
      the ionosphere during Heating and EISCAT operation. In 1993 the
      instrument was transferred to EISCAT Scientific Association and
      since 1994 it has been used for continual ionosoundings in
      intervals from 12 down to 2 minutes.
