Global population exposure to landscape fire air pollution from 2000 to 2019.

ABSTRACT: Wildfires are thought to be increasing in severity and frequency as a result of climate change^1-5. Air pollution from landscape fires can negatively affect human health^4-6, but human exposure to landscape fire-sourced (LFS) air pollution has not been well characterized at the global scale^7-23. Here, we estimate global daily LFS outdoor fine particulate matter (PM_2.5) and surface ozone concentrations at 0.25° × 0.25° resolution during the period 2000-2019 with the help of machine learning and chemical transport models. We found that overall population-weighted average LFS PM_2.5 and ozone concentrations were 2.5 µg m^-3 (6.1% of all-source PM_2.5) and 3.2 µg m^-3 (3.6% of all-source ozone), respectively, in
