Old-style 3-hour PSI, worst region
By region
Current PM2.5 is the latest 1-hour reading. 3-hour PSI uses the average of the last three hourly readings. 24-hour PSI is NEA's official figure.
| Region | PM2.5 now (µg/m³) | 3h PSI | 24h PSI |
|---|
Past 24 hours
PM2.5 in µg/m³ for each region. The 3-hour and 24-hour views are rolling averages ending at each hour. Shaded bands show the PSI band each PM2.5 level falls in.
Cigarette equivalent
Rough rule of thumb from Berkeley Earth: breathing 22 µg/m³ of PM2.5 over 24 hours is about one cigarette. It is an illustration of exposure, not a medical measurement.
–cigarettes over the past 24 hours (island-wide average)
–cigarettes in the last hour
–cigarettes per day if this hour's level continued
