Wind LiDAR measurement campaign at CESAR Observatory in Cabauw: preliminary results

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.
