smooth_gaussian

smooth_gaussian(fs, sigma=1, repeat=1, **kwargs)

New in metview-python version 1.13.0.

Performs spatial smoothing using a Gaussian filter for each field in fs.

Parameters

  • fs (Fieldset) – input fieldset

  • sigma (number) – standard deviation for Gaussian kernel

  • repeat (number) – specifies how many times the smoothing should be applied to fs

  • **kwargs –

    these arguments are directly passed to scipy.ndimage.gaussian_filter() (see below)

Return type

Fieldset

The computations are performed by calling scipy.ndimage.gaussian_filter() and the extra **kwargs are directly passed to this function.

Warning

smooth_gaussian() has some limitations:

  • it only works for regular latitude-longitude grids

  • for global grids in longitudinal (East-West) direction the resulting field is not smoothed properly along the periodic border

Note
