Fields RHI and SURV Volumes:

    PHIDP - differential phase (degrees)
    KDP - specific differential phase (deg/km) that should likely be recomputed from phase
    DBZ, DBZ_TOT: Radar reflectivity fields (DZ is copy of DBZ; dBZ)
    SQI - Signal Quality Index - see Vaisala user's manual for details (referenced in article)
    WIDTH: Spectrum width (m/s)
    ZDR: Differential reflectivity (dB)
    RHOHV: correlation coefficient
    VEL:original, unedited radar Doppler velocity field (m/s)

Fields (KLTX or SR1 volumes):

    PHIDP or PHI - differential phase (degrees)
    KDP - specific differential phase (deg/km) that should likely be recomputed from phase
    VRo - original, unedited radar Doppler velocity field (m/s)
    DBZ, DZ, or REF: Radar reflectivity fields (DZ is copy of DBZ; dBZ)
    SQI (SR1 only) - Signal Quality Index - see Vaisala user's manual for details (referenced in article)
    WIDTH or SW: Spectrum width (m/s)
    ZDR: Differential reflectivity (dB)
    RHOHV or RHO: correlation coefficient
    VEL: intermediate Doppler velocity fields between the original and final versions
    VT, VE, or VD: Final version of the Doppler velocity field (this is the field used for dual-Doppler)
    VT2: Not included for all sweeps/volumes - dummy field that can be ignored if included.

Dual-Doppler Analysis (dda) Volumes
        1D Fields:
                X - one-dimensional array for x-distances from KLTX (in kilometers)
                Y - one-dimensional array for y-distances from KLTX (in kilometers)
                Z - one-dimensional array for z-distances above mean sea level (in kilometers)
Note: KLTX is located at 33.9892_ N, -78.4291_ W._

        3D Fields (of dimensions NX, NY, NZ, where NX, NY, and NZ are the number of grid
        points corresponding to the X, Y, and Z arrays):
                U - east-west component of the horizontal wind (m/s)
                V - north-south component of the horizontal wind (m/s)
                W - vertical wind (m/s)
                CVG - coverage array (1 = good data; 0 = bad data)
                CVG2 - extra coverage array
                MAXDBZ - maximum radar reflectivity observed by either SR1 or KLTX
