SINGAPORE, Oct 22 — Residents in Singapore on Thursday (October22) woke up to better air quality for a fifth consecutive day — a run that began on October2218.
While hourly PM2.5 and 24-hour Pollutant Standards Index (PSI) have not returned to levels recorded before September 4, when air quality entered the unhealthy range for the first time this year, hourly concentration readings have stayed in the normal to low-elevated bands over the past days.
The improvement came as winds turned to blow from the south.
Meanwhile, PSI was in the good-to-moderate range in all regions, except in western Singapore with a low-unhealthy PSI of 108.
