Use current AQI and its observation time in a location report. An old reading cannot tell you what the air is like now.
Comparing places long term?
Use annual PM2.5 and historical patterns. The 0–100 Clean Air Score is a comparison model, not the current AQI scale.
COMPARE TWO PLACES
Which city has cleaner air over time?
Compare annual PM2.5, historical scores and trends side by side. Check each report’s dates and whether its data is local or a nearby reference.
