wradlib.qual.beam_block_frac(th, bh, a)

Partial beam blockage fraction.

Note

From Bech et al. (2003), Eqn 2 and Appendix

Parameters
Returns

pbb (float) – Partial beam blockage fraction [unitless]

Examples

>>> pbb = beam_block_frac(th,bh,a)


Note

This procedure uses a simplified interception function where no vertical gradient of refractivity is considered. Other algorithms treat this more thoroughly. However, this is accurate in most cases other than the super-refractive case.

See the the half_power_radius function to calculate variable a.

The heights must be the same units!
