Air quality in Fengcheng right now
Right now the modelled US Air Quality Index for Fengcheng, Liaoning, China is 36, 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 36. 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 6.9 µg/m³, within the WHO 24-hour guideline of 15 µg/m³; PM10 is 7.4 µg/m³ against a guideline of 45; ozone is 33 µg/m³ (below the WHO 8-hour level of 100); nitrogen dioxide is 16 µg/m³ (below the 24-hour guideline of 25).
Also this hour: UV index 0.9, carbon monoxide 184 µg/m³.
NASA FIRMS shows 136 fire hotspots within 300 km in the last day (nearest about 19 km), but particle levels are not elevated enough to point to smoke right now.
