pyrad.proc.process_rhohv_rain#

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

Keeps only suitable data to evaluate the 80 percentile of RhoHV in rain

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, must contain
    "RhoHV" or "RhoHVc" or "uRhoHV", and,
    "dBZ" or "dBZc", and
    "TEMP" (Optional), or
    "H_ISO0" (Optional)
rmin : float. Dataset keyword
    minimum range where to look for rain [m]. Default 1000.
rmax : float. Dataset keyword
    maximum range where to look for rain [m]. Default 50000.
Zmin : float. Dataset keyword
    minimum reflectivity to consider the bin as precipitation [dBZ].
    Default 20.
Zmax : float. Dataset keyword
    maximum reflectivity to consider the bin as precipitation [dBZ]
    Default 40.
ml_thickness : float. Dataset keyword
    assumed thickness of the melting layer. Default 700.
fzl : float. Dataset keyword
    The default freezing level height. It will be used if no
    temperature field name is specified or the temperature field is
    not in the radar object. Default 2000.
sounding : str. Dataset keyword
    The nearest radiosounding WMO code (5 int digits). It will be used to
    compute the freezing level, if no temperature field name is specified,
    if the temperature field isin the radar object or if no freezing_level
    is explicitely defined.

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

Returns:

  • new_dataset (dict) – dictionary containing the output field “RhoHV_rain” (RhoHV in rain)

  • ind_rad (int) – radar index
