pyart.correct._fourdd_interface.fourdd_dealias(DZvolume, radialVelVolume, hc, sc, dc, vad_time, prep, filt)

Dealias using the FourDD algorithm.

Parameters :

DZvolume : _RslVolume

Reflectivity to use when thresholding is selected.

radialVelVolume : _RslVolume

Radial velocities which will be dealiased.

hc : array

Sounding heights in meters. Must be a contiguous one-dimensional float32 array.

sc : array

Sounding wind speed in m/s. Must be a contiguous one-dimensional float32 array.

dc : array

Sounding wind direction in degrees. Must be a contiguous one-dimensional float32 array.

vad_time : int

Time of sounding in YYDDDHHMM format.

prep : int

Flag controlling thresholding of DZvolume, 1 = yes, 0 = no.

filt : int

Flag controlling Bergen and Albers filter, 1 = yes, 0 = no.

debug : bool

True to return debugging RSL Volume objects for debugging: usuccess, DZvolume, radialVelVolume, unfoldedVolume, sondVolume

Returns :

usuccess : int

Flag indicating if the unfolding was successful, 1 = yes, 0 = no.

data : array

Array of unfolded velocities.
