Ozone (O₃) concentration
Population-weighted average ozone (O₃) concentrations in parts per billion (ppb). Local concentrations of ozone are recorded and estimated at a 11x11km resolution. These values are subsequently weighted by population-density for calculation of nation-level average concentrations.
