TerraOverview interpretation: ozone zone exceeding the health target value
Some Regions declare a zoning for ozone distinct from the one used for the other pollutants, and the point falls in one of those zones. In the reference year the target value for the protection of human health was exceeded. Ozone is a secondary pollutant, formed in the atmosphere on hot sunny days and affecting wide areas: it is the case where the scale of a zone is more meaningful, not less.
