Computes attenuation caused by precipitation.
By Ulrich Blahak (and Isztar Zawadski, Heikki Pohjola, Jarmo Koistinen), for liquid precipitation (including bright band):
![\[ k(Z) = 1.12\cdot10^{-4} Z_e^{0.62} \]](form_0.png)
and for snow:
![\[ k(Z) = 1.1\cdot10^{-7} Z_e + 2.1\cdot10^{-5} Z_e^{0.5} \]](form_1.png)
Hence, the general expression for precipitation attenuation is
![\[ k(Z) = c Z_e^p + c_2 Z_e^{p_2}. \]](form_2.png)
