Miri haze today: air quality and PM2.5 forecast

Friday 9 October: the CAMS global model forecasts a daily mean of 15.8 µg/m³ PM2.5 for Miri today, above the WHO 24-hour guideline of 15 µg/m³; the highest of the next days is 15.8 µg/m³. These are model values. For the official Air Pollutant Index (API) see APIMS (Department of Environment Malaysia, live Air Pollutant Index, API).

Forecast bars: daily mean PM2.5 from the Copernicus CAMS global model, as computed, against 150 µg/m³. Green is within the WHO 24-hour guideline (15 µg/m³), amber above it, red above the WHO interim target 1 (75 µg/m³). Model values, not monitor readings.

Haze and allergy in Miri

Miri, in northern Sarawak near the border with Brunei, is surrounded by large peat swamps. In long dry spells peat fires close to the city, such as those around Kuala Baram, can cover Miri in smoke even when there is little transboundary haze, and peat fires are hard to put out because they smoulder underground. In the worst years Miri is also reached by smoke from Kalimantan. The northeast monsoon from November to March brings the heaviest rain and the cleanest air of the year.
