When it applies
Source class
O3_VALUTAZIONE_INCOMPLETA
The rule fires when the named source publishes this class for the point being asked about. Until the source does, TerraOverview adds nothing.
TerraOverview interpretation: ozone zone with no established exceedance, insufficient data
The point falls in a zone declared for ozone alone, and for the reference year the data reported were not sufficient to establish whether the target value was exceeded. The source asserts neither compliance nor exceedance.
