Method and limitations
Method and limitations
No missing value is imputed. Where colour classes are used, their breaks and colours come from the catalogue; source-declared suppression remains missing.
The area mean gives every published geographic area equal weight. It is not weighted by population, exposure or area size.
IRCEL-CELINE daily population-weighted RIO 4 x 4 km concentrations, harmonised by the publisher to the municipality status after the 2019 fusion.
