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

Estimates rainfall rate from polarimetric moments

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
RR_METHOD : string. Dataset keyword
    The rainfall rate estimation method. One of the following:
    Z, ZPoly, KDP, A, ZKDP, ZA, hydro
alpha, beta : float
    factor and exponent of the R-Var power law R = alpha*Var^Beta.
    Default value depending on RR_METHOD. Z (0.0376, 0.6112),
    KDP (None, None), A (None, None)
alphaz, betaz : float
    factor and exponent of the R-Z power law R = alpha*Z^Beta.
    Default value (0.0376, 0.6112)
alphazr, betazr : float
    factor and exponent of the R-Z power law R = alpha*Z^Beta applied
    to rain in method hydro. Default value (0.0376, 0.6112)
alphazs, betazs : float
    factor and exponent of the R-Z power law R = alpha*Z^Beta applied
    to solid precipitation in method hydro. Default value (0.1, 0.5)
alphakdp, betakdp : float
    factor and exponent of the R-KDP power law R = alpha*KDP^Beta.
    Default value (None, None)
alphaa, betaa : float
    factor and exponent of the R-Ah power law R = alpha*Ah^Beta.
    Default value (None, None)
thresh : float
    In hybrid methods, Rainfall rate threshold at which the retrieval
    method used changes [mm/h]. Default value depending on RR_METHOD.
    ZKDP 10, ZA 10, hydro 10
mp_factor : float
    Factor by which the Z-R relation is multiplied in the melting layer
    in method hydro. Default 0.6

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

Returns:

new_dataset (dict) – dictionary containing the output
