pyrad.proc.process_colocated_gates(procstatus, dscfg, radar_list=None)[source]#

Find colocated gates within two radars

Parameters:

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

  • dscfg (dictionary of dictionaries) –

    data set configuration. Accepted Configuration Keywords:

    datatype : list of string. Dataset keyword
    The input data types to use to check colocated gates (one for every radar)
    Any datatype supported by pyrad and available in both radars is accepted.
    If visibility filtering is desired, the fields
    "visibility" or "visibility_polar" must be specified for both radars.
