pysteps.verification.spatialscores.intensity_scale

pysteps.verification.spatialscores.intensity_scale(X_f, X_o, name, thrs, scales=None, wavelet='Haar')

Compute an intensity-scale verification score.

Parameters:

X_f : array_like

Array of shape (n,m) containing the forecast field.

X_o : array_like

Array of shape (n,m) containing the verification observation field.

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 : sequence

A sequence of intensity thresholds for which to compute the verification.

scales : sequence, optional

A sequence of spatial scales in pixels to be used in the FSS.

wavelet : str, optional

The name of the wavelet function to use in the 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 : array_like

The two-dimensional array containing the intensity-scale skill scores for each spatial scale and intensity threshold.
