pyrad.proc.process_dealias_region_based

pyrad.proc.process_dealias_region_based(procstatus, dscfg, radar_list=None)

Dealiases the Doppler velocity field using a region based algorithm

Parameters:

• procstatus (int) – Processing status: 0 initializing, 1 processing volume, 2 post-processing

• dscfg (dictionary of dictionaries) –

  data set configuration. Accepted Configuration Keywords:

  datatype : string. Dataset keyword
      The input data type
  interval_splits : int, optional
      Number of segments to split the nyquist interval into when finding
      regions of similar velocity.  More splits creates a larger number
      of initial regions which takes longer to process but may result in
      better dealiasing.  The default value of 3 seems to be a good
      compromise between performance and artifact free dealiasing. This
      value is not used if the interval_limits parameter is not None.
  skip_between_rays, skip_along_ray : int, optional
      Maximum number of filtered gates to skip over when joining
      regions, gaps between region larger than this will not be
      connected. Parameters specify the maximum number of filtered gates
      between and along a ray. Set these parameters to 0 to disable
      unfolding across filtered gates.
  centered : bool, optional
      True to apply centering to each sweep after the dealiasing
      algorithm so that the average number of unfolding is near 0. False
      does not apply centering which may results in individual sweeps
      under or over folded by the nyquist interval.
  nyquist_vel : float, optional
      Nyquist velocity of the aquired radar velocity.
      Usually this parameter is provided in the
      Radar object intrument_parameters. If it is not available it can
      be provided as a keyword here.
  

• radar_list (list of Radar objects) – Optional. list of radar objects

Returns:

• new_dataset (dict) – dictionary containing the output

• ind_rad (int) – radar index
