That is the fine-particle pollution you'd breathe standing outside all day inRegina right now, turned into a number your body already understands.
A health-impact equivalence, not literal smoking: Berkeley Earth puts a full day at 22 µg/m³ of PM2.5 at about one cigarette.How we work this out
Why live rankings?
Smoke plumes are patchy and move with changing winds, terrain and weather. Nearby lakefront, coastal and higher-elevation places can be much clearer than Regina, but no direction is reliably cleaner. That is why this list is recalculated from live PM2.5 readings every hour instead of publishing a fixed escape route. If everything within three hours is smoky, the rankings will say so. Sometimes the honest answer is to stay inside with a filter running.
