pysteps.utils.transformation.dB_transform¶

pysteps.utils.transformation.dB_transform(R, metadata=None, threshold=None, zerovalue=None, inverse=False)¶

Methods to transform precipitation intensities to/from dB units.

Parameters:

R : array-like: Array of any shape to be (back-)transformed.
metadata : dict: Metadata dictionary containing the transform, zerovalue and threshold attributes as described in the documentation of pysteps.io.importers.
threshold : float: Optional value that is used for thresholding with the same units as R. If None, the threshold contained in metadata is used.
zerovalue : float: Optional value to be assigned to no rain pixels as defined by the threshold.
inverse : bool: Optional, if set to True, it performs the inverse transform

Returns:
