Convert to rain rate [mm/h].
- Parameters
- R: array-like
Array of any shape to be (back-)transformed.
- metadata: dict
Metadata dictionary containing the accutime, transform, unit, threshold and zerovalue attributes as described in the documentation of

.Additionally, in case of conversion to/from reflectivity units, the zr_a and zr_b attributes are also required, but only if zr_a = zr_b = None. If missing, it defaults to Marshall–Palmer relation, that is, zr_a = 200.0 and zr_b = 1.6.
- zr_a, zr_b: float, optional
The a and b coefficients of the Z-R relationship (Z = a*R^b).
- Returns
- R: array-like
Array of any shape containing the converted units.
- metadata: dict
The metadata with updated attributes.
