pyorc.Velocimetry.mask.variance

Velocimetry.mask.variance(tolerance=5, mode='and')

Mask locations if their variance (std/mean in time) is above a tolerance level.

This is calculated for either or both x and y direction.

Parameters:

• tolerance (float) – amount of standard deviations allowed from the mean

• mode (str) – can be “and” (default) or “or”. If “or” (“and”), then only one (both) of two vector components need(s) to be within tolerance.

Returns:

mask – mask applicable to input dataset with ds.velocimetry.filter(mask). If inplace=True, the dataset will be returned masked with mask.

Return type:

xr.DataArray
