Functions

x2xdb(xls)	Convert linear-scale values to log scale (dB).
xdb2x(xdb)	Convert log scale (dB) values to linear-scale.

Module Contents

towerpy.utils.unit_conversion.x2xdb(xls)

Convert linear-scale values to log scale (dB).

Parameters

xlsfloat or array

Values in linear scale.

Returns

xdbfloat or array

Values in dB scale.

Notes

\[dBx = 10log_{10}x\]

Examples

>>> # Convert radar reflectivity in linear scale (mm^6 m^-3) to dBZ.
>>> import towerpy as tp
>>> zls = 39811
>>> zdbz = tp.utils.radutilities.x2xdb(zls)
>>> print(zdbz)

towerpy.utils.unit_conversion.xdb2x(xdb)

Convert log scale (dB) values to linear-scale.

Parameters

xdbfloat or array

Values in dB scale.

Returns

xlsfloat or array

Values in linear scale.

Notes

\[x = 10^{0.1*dBx}\]

Examples

>>> # Convert radar reflectivity in dBZ to linear scale (mm^6 m^-3).
>>> import towerpy as tp
>>> dbz = 50
>>> zls = tp.utils.radutilities.xdb2x(dbz)
>>> print(zls)
