pysteps.verification.spatialscores.intensity_scale_init¶

pysteps.verification.spatialscores.intensity_scale_init(name, thrs, scales=None, wavelet='Haar')¶

Initialize an intensity-scale verification object.

Parameters

name: string

A string indicating the name of the spatial verification score to be used:

Name	Description
FSS	Fractions skill score
BMSE	Binary mean squared error

thrs: float or array_like

Scalar or 1-D array of intensity thresholds for which to compute the verification.

scales: float or array_like, optional

Scalar or 1-D array of spatial scales in pixels, required if name="FSS".

wavelet: str, optional

The name of the wavelet function, required if name="BMSE". Defaults to the Haar wavelet, as described in Casati et al. 2004. See the documentation of PyWavelets for a list of available options.

Returns

out: dict: The intensity-scale object.
