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 units argument, or if this is None, the units on data are used.

Parameters

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

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

• **kwargs (Arbitrary keyword arguments passed to numpy.ma.masked_array) –

Returns

pint.Quantity
