masked_array#

metpy.units.masked_array(data, data_units=None, **kwargs)[source]#

Create a numpy.ma.MaskedArray with units attached.

This is a thin wrapper around numpy.ma.MaskedArray 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
