The _FillValue CF attribute.
This attribute is forced to be consistent with the missing_value attribute as follows:
- Assigning a value to the missing_value attribute also assigns the same value to the _FillValue attribute whether the latter has been previously set or not.
- Assigning a value to the _FillValue attribute also assigns the same value to the missing_value attribute, but only if the latter has previously been defined.
Examples
>>> f._FillValue = -1e30
