Hi.
I agree with Charlie and Jessica that _FillValue is the better approach.
According to the NUG, "The fill value is returned when reading values
that were never written." This contrasts slightly with the missing_value
definition which is (per NUG) "The missing_value attribute can be a
scalar or vector containing values indicating missing data."
Missing_value has more of the sense of "Our acquisition system couldn't
get a value for this measurement at this time/place."
In the case at hand, there never were values to potentially have. The
difference between not existing and potentially existing but unavailable.
Grace and peace,
Jim

Matlab, Panoploy and other software know what to do with _/FillValue,
I don’t know if the same can be said about missing/_value

I prefer _FillValue to missing_value.
