Short summary
Hazard reduction burns (HRBs) may prevent wildfires, but both generate PM2.5 air pollution. We identify the meteorological factors linked to high PM2.5 pollution & assess how they differ between HRB days with low vs. high PM2.5. Boundary layer, cloud cover, temperature & wind speed strongly influence PM2.5, with these factors being more variable & higher in magnitude during mornings & evenings of HRB days when PM2.5 remains low, indicating how HRB timing can be altered to reduce air pollution.
