pysteps.blending.utils.recompose_cascade#
- pysteps.blending.utils.recompose_cascade(combined_cascade, combined_mean, combined_sigma)#
Recompose the cascades into a transformed rain rate field.
- Parameters:
combined_cascade (array-like) – An array of shape [scale_level, y, x] containing per scale level (cascade) the weighted combination of cascades from multiple components (NWP, nowcasts and noise) to be used in STEPS blending.
combined_mean (array-like) – An array of shape [scale_level, …] similar to combined_cascade, but containing the normalization parameter mean.
combined_sigma (array-like) – An array of shape [scale_level, …] similar to combined_cascade, but containing the normalization parameter standard deviation.
- Returns:
out – A two-dimensional array containing the recomposed cascade.
- Return type:
array-like
