a–d Country-scale PAF for total (> AQG) and three short-term O₃ exposure intervals (AQG-IT2, IT2-IT1, and > IT1). e–h Country-scale PAF for total (> AQG) and three long-term O₃ exposure intervals (AQG-IT2, IT2-IT1, and > IT1). The short- and long-term gridded PAF with more details at a high spatial resolution can be referred to in Supplementary Fig. 8. Colour bars stand for the values of PAF. Definitions of acronyms: AQG (air quality guideline, 50.11 ppb for short term and 30.07 ppb for long term), IT2 (interim target 2, 60.13 ppb for short term and 35.08 ppb for long term), and IT1 (interim target 1, 80.18 ppb for short term and 50.11 ppb for long term).
