It looks like your extension 'radationhours' is not prepared for the case
where outTemp is either missing from a record, or has a value of None. You
must check for these cases.
Also, it should not be necessary to cast the value as a float: it's already
either a float, or None.
As for why outTemp would be missing from the record, or have a value of
None, that's hard to say. It would depend on what processing has occurred
earlier in the engine pipeline.
