In order to avoid the effect of CINRAD/SA Weather Radar at Huangshan Station on Parsivel spectrometer valid observations, the reasons for the effect and the processing method are discussed. A steel mesh is placed in the appropriate location between radar and Parsivel spectrometer, based on the property of metal, which can absorb electromagnetic waves. The results show that the steel mesh can completely shield the effect of the radar on Parsivel spectrometer and the reliability of observational data can be protected well.
