masked_array

metpy.units.masked_array(data, data_units=None, **kwargs)

Create a numpy.ma.MaskedArray with units attached.

This is a thin wrapper around numpy.ma.masked_array() that ensures that units are properly attached to the result (otherwise units are silently lost). Units are taken from the data_units argument, or if this is None, the units on data are used.

Parameters

• data (array_like) – The source data. If data_units is None, this should be a pint.Quantity with the desired units.

• data_units (str or pint.Unit, optional) – The units for the resulting pint.Quantity

• kwargs – Arbitrary keyword arguments passed to numpy.ma.masked_array, optional

Returns

pint.Quantity
