DZ Reflectivity (dBZ), may contain some DZ_INDEX signal-processor level QC and/or filters. This field would contain Darwin's CZ, or WSR88D's standard reflectivity. In other words, unless the field is described otherwise, it should always go here. In essence, this is the "cleanest" reflectivity field for a radar. VR Radial Velocity (m/s) VR_INDEX SW Spectral Width (m2/s2) SW_INDEX CZ QC Reflectivity (dBZ), contains post-processed QC'd data CZ_INDEX ZT Total Reflectivity (dBZ) ZT_INDEX May be uncommon, but important DR Differential reflectivity DR_INDEX DR and LR are for dual-polarization radars only. Unitless or in dB. LR Another form of differential ref LR_INDEX called LDR, not sure of unitsThis function is a one line C function. Observe the following:
Radar *radar; Volume *v; /* The following two lines are identical. */ v = Vget_volume(radar, DZ_INDEX); v = radar->v[DZ_INDEX];
