Air quality in Kuala Krai right now
Right now the modelled US Air Quality Index for Kuala Krai, Kelantan, Malaysia is 18, which falls in the "Good" band (up to 50). Air quality is satisfactory and poses little or no risk; a good time for outdoor activity.
The index is driven mainly by PM2.5, whose own sub-index is 18. 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 5.5 µg/m³, within the WHO 24-hour guideline of 15 µg/m³; PM10 is 5.7 µg/m³ against a guideline of 45; ozone is 37 µg/m³ (below the WHO 8-hour level of 100); nitrogen dioxide is 1.5 µg/m³ (below the 24-hour guideline of 25).
Also this hour: UV index 2.1, carbon monoxide 493 µg/m³.
NASA FIRMS shows 1 fire hotspot within 300 km in the last day (nearest about 271 km), but particle levels are not elevated enough to point to smoke right now.
