  A two-year verification campaign of the ZephIR~300 vertical profiling wind
LiDAR has recently been started by the Royal Netherlands Meteorological
Institute (KNMI) at the CESAR Observatory (Cabauw Experimental Site for
Atmospheric Research) in Cabauw, The Netherlands. In this paper we present
preliminary results of the first six months of this campaign (February 14 -
July 31, 2018), focusing on the (height-dependent) data availability of the
ZephIR~300 under various meteorological conditions (precipitation intensity,
cloud base height and visibility) and the data quality via a comparison with in
situ wind measurements at several levels in the 213-m tall meteorological mast.
