Abstract
The prime interest from the Danish Meteorological Institute in the
proposed LOFAR/LOIS system arises from the possible use of the
system in weather radar applications for the detection of vertical
and horizontal motions of air masses, heat, waves and turbulences.
Of particular interest are the coupling processes between the upper
and lower atmospheric regions. Compared to available wind profiler
systems and MST (Mesosphere-Stratosphere-Troposphere) radars the
proposed LOFAR/LOIS system offers versatile frequency selection over
a wide range, much enhanced transmitter power and immensely
increased receiver sensitivity and directivity. With this
combination the proposed LOFAR/LOIS system will most likely enable
an in-depth exploration of all aspects and the full potential of
ground-based weather radar systems.
In addition, the DMI has considerable interests in possible space
weather applications and in the use of the proposed LOFAR/LOIS radar
system for ionospheric and magnetospheric soundings. Of particular
interest is the possible use of the LOFAR/LOIS system to detect the
characteristics of magnetospheric/ionospheric regions, in particular
the transition between the high-density low-latitude Plasmasphere,
the low density mid-latitude Through region and the variable-density
high-latitude Auroral region. Another interesting application of the
receiving section of the system is its possible use as an imaging
riometer system to detect ionospheric absorption events and
investigate scintillation processes.
