wradlib.atten.correct_attenuation_hb(gateset, coefficients={'a': 0.000167, 'b': 0.7, 'gate_length': 1.0}, mode='except', thrs=59.0)
Parameters: gateset (numpy.ndarray) – multidimensional array. The range gates (over which iteration has to be performed) are supposed to vary along the last dimension so, e.g., for a set of l radar images stored in polar form with m azimuths and n range-bins the input array’s shape can be either (l,m,n) or (m,l,n) data has to be provided in decibel representation of reflectivity [dBZ] a (float) – proportionality factor of the k-Z relation ($$k=a \cdot Z^{b}$$). Per default set to 1.67e-4. b (float) – exponent of the k-Z relation ( $$k=a \cdot Z^{b}$$ ). Per default set to 0.7. gate_length (float) – length of a range gate [km]. Per default set to 1.0. mode (string) – controls how the function reacts, if the sum of signal and attenuation exceeds the threshold thrs Possible values: ’warn’ : emit a warning through the module’s logger but continue execution ’zero’ : set offending gates to 0.0 ’nan’ : set offending gates to nan ’except’: raise an AttenuationOverflowError exception Any other mode will also raise the Exception. thrs (float) – threshold, for the sum of attenuation and signal, which is considered implausible. pia (numpy.ndarray) -- Array with the same shape as gateset containing the calculated attenuation [dB] for each range gate. AttenuationOverflowError – Exception, if attenuation exceeds thrs and no handling mode` is set.
