pollutants: PM10, NO2, O3
each pollutant considered separately
AQ index: annual mean modelled concentration
two methods:
fixed threshold
similarity criterion: concentration in range Cstation ±20%
(relative tolerance)
▸ absolute cutoff: concentration in range Cstation ± 2µg/m³
(absolute tolerance) is ok, even if similarity criterion is not
satisfied
uncertainty-dependent threshold (UDT) similarity criterion: concentration
in range Cstation U95 (Cstation) 1
spatial representativeness (SR) region can be discontiguous
► SR region is limited to the IPR AQ zone
1 as described in the Guidance [Janssen et al., 2017] and implemented in R package dartle
