pyrad.proc.process_attenuation#

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

Computes specific attenuation and specific differential attenuation using the Z-Phi method and corrects reflectivity and differential reflectivity

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,
    "dBZ" or "dBZc", and,
    "PhiDP" or "PhiDPc", and,
    "ZDR" or "ZDRc", and
    "TEMP" or "H_ISO0" (Optional)
ATT_METHOD : float. Dataset keyword
    The attenuation estimation method used. One of the following:
    ZPhi, Philin. Default ZPhi
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 is in 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 fields “Ah” (spec. attenuation), “PIA” (path-integrated attenuation) and “dBZc” (corr. refl.)
ind_rad (int) – radar index
