Air quality in Batam right now
Right now the modelled US Air Quality Index for Batam, Riau, Indonesia is 80, which falls in the "Moderate" band (up to 100). Acceptable for most people. Unusually sensitive people should consider shortening long or heavy exertion outdoors.
The index is driven mainly by PM2.5, whose own sub-index is 80. Fine and coarse particles come from traffic, heating, industry, dust and smoke; they build up on calm nights and clear when wind or rain arrives.
PM2.5 is 7.3 µg/m³, within the WHO 24-hour guideline of 15 µg/m³; PM10 is 7.3 µg/m³ against a guideline of 45; ozone is 44 µg/m³ (below the WHO 8-hour level of 100); nitrogen dioxide is 41 µg/m³ (above the 24-hour guideline of 25).
Also this hour: carbon monoxide 950 µg/m³.
NASA FIRMS shows 24 fire hotspots within 300 km in the last day (nearest about 260 km), but particle levels are not elevated enough to point to smoke right now.
