Air quality (PM10/PM2.5)

Category	Health determinants
Dimension	Physical Env.
Description	Annual mean µg/m3 (microgramme per cubic metre) for particulate matter with an aerodynamic diameter of less than or equal to 10 micrometres (PM10) or 2.5 micrometres (PM2.5)
Indicator/Index/Metrics	$\text{Annual mean PM}_{10} (\mu g/m^3) = \frac{\sum_{i=1}^{n} \text{PM}_{10_i}}{n}$ $\text{Annual mean PM}_{2.5} (\mu g/m^3) = \frac{\sum_{i=1}^{n} \text{PM}_{2.5_i}}{n}$
Note	The annual PM2.5 guideline level recommended by the WHO is 5 µg/m³. The annual interim targets for PM2.5 start at 35 µg/m³ (target 1) and decrease to 25, 15, and 10 µg/m³ for targets 2, 3, and 4, respectively. The annual PM10 guideline level recommended by the WHO is 15 µg/m³. The annual interim targets for PM10 start at 70 µg/m³ (target 1) and decrease to 50, 30, and 20 µg/m³ for targets 2, 3, and 4, respectively.
Data	Remote sensing data
