Using WSR-88D Polarimetric Data to Identify Bird-Contaminated Doppler Velocities

Table 3

Typical ranges of 𝑍_DR, Φ_DP, and 𝜌_hv and height for BSb, BSi, and MS.

	𝑍DR	ΦDP	𝜌hv	Height
BSb	<3 dB	70–100°	<0.97	Mostly below melting layer
BSi	≥2 dB	40°	<0.97	Below melting layer and mainly in boundary layer
MS	−2~6 dB		>0.97
