wradlib.trafo.kdp_to_r(kdp, f, a=129.0, b=0.85)

Estimating rainfall intensity directly from specific differential phase.

The general power law expression has been suggested by [Ryzhkov2005].

The default parameters have been set according to [Bringi2001].

Note

Please note that this way, rainfall intensities can become negative. This is an intended behaviour in order to account for noisy $$K_{DP}$$ values.

Parameters: kdp (float) – $$K_{DP}$$ as array of floats f (float) – radar frequency [GHz] Standard frequencies in X-band range between 8.0 and 12.0 GHz, Standard frequencies in C-band range between 4.0 and 8.0 GHz, Standard frequencies in S-band range between 2.0 and 4.0 GHz. a (float) – linear coefficient of the power law b (float) – exponent of the power law output (array) – array of rainfall intensity
