The missing_value CF property.

A value used to represent missing or undefined data (deprecated by the netCDF user guide). See for details.

Note that this attribute is used primarily for writing data to disk and is independent of the missing data mask. It may, however, be used when unmasking data array elements.

The recommended way of retrieving the missing data value is with the fill_value method.

>>> f.missing_value = 1.0e30
>>> f.missing_value
>>> del f.missing_value

Mask the data array where it equals a missing data value:

>>> f.setitem(cf.masked, condition=f.fill_value()) DCH
