wradlib.trafo.TrafoMethods

class wradlib.trafo.TrafoMethods(obj)

Bases: XarrayMethods

wradlib xarray SubAccessor methods for DualPol.

decibel()

Calculates the decibel representation of the input values

\(dBZ=10 \cdot \log_{10} z\)

Parameters:

x (float or numpy.ndarray) – (must not be <= 0.)

Examples

>>> from wradlib.trafo import decibel
>>> print(decibel(100.))
20.0

idecibel()

Calculates the inverse of input decibel values

\(z=10^{x \over 10}\)

Parameters:

x (float or numpy.ndarray)

Examples

>>> from wradlib.trafo import idecibel
>>> print(idecibel(10.))
10.0

r_to_depth(interval)

Computes rainfall depth (mm) from rainfall intensity (mm/h)

Parameters:

• x (float or numpy.ndarray) – rainfall intensity in mm/h

• interval (float) – time interval (s) the values of x represent

Returns:

output (float or numpy.ndarray) – rainfall depth (mm)

decibel()	Calculates the decibel representation of the input values
idecibel()	Calculates the inverse of input decibel values
r_to_depth(interval)	Computes rainfall depth (mm) from rainfall intensity (mm/h)
