The name is not totally arbitrary. The service StdWXCalculate needs to
calculate weather-related quantities, such as dewpoint. Hence, it needs a
weather-related binding.
If you don't provide one, then it guesses wx_binding. If that's not the
same as the binding used by the database, then it warns you. That's what
the entry, "The StdWXCalculate data binding (wx_binding) does not match the
StdArchive data binding (cmon_binding)" is all about.
You have two choices. Either tell it that it can find what it needs using
cmon_binding:
[StdWXCalculate]
data_binding = cmon_binding
[[Calculations]]
...
or remove StdWXCalculate from the list of services to be run.
