Data Quality of 3836 Polarimetric Radar and Its Observation of Melting-Layer

The technical status of the upgraded 3836 C-band dual-linear polarimetric Doppler radar (3836 even radar) is reported first. Then this study analyses its data quality and its detection ability. A model is established in which the bright band can be identified by applying the fuzzy logic method to the four polarimetric radar observation variables. The radar data are used to assess the result from the model and the variety features of different phased hydrometeors in the melting-layer bright band are also discussed
