Extended Data Fig. 10: Variation in indoor PM2.5 across monitors with similar outdoor PM2.5 during the Aug/Sep 2020 smoke event in the Bay Area.

From: Exposures and behavioural responses to wildfire smoke

Extended Data Fig. 10

Each dot is average outdoor PM2.5 and average indoor PM2.5 for an individual monitor in the Bay Area over the Aug/Sep 2020 smoke event, with monitors grouped into 5 μg/m3bins based on outdoor exposure. Numbers at top show the number of monitors in each bin (black), and the ratio of maximum to minimum indoor PM2.5 across monitors within each outdoor PM2.5 bin (red). Monitors with average outdoor PM2.5 exposures within 5 μg/m3of each other experienced > 20x differences in indoor PM2.5 exposures.
