Air quality in Forlì right now
Right now the modelled US Air Quality Index for Forlì, Emilia-Romagna, Italy 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 14 µg/m³, within the WHO 24-hour guideline of 15 µg/m³; PM10 is 20 µg/m³ against a guideline of 45; ozone is 33 µg/m³ (below the WHO 8-hour level of 100); nitrogen dioxide is 8 µg/m³ (below the 24-hour guideline of 25).
Also this hour: carbon monoxide 203 µg/m³.
NASA FIRMS shows 7 fire hotspots within 300 km in the last day (nearest about 129 km), but particle levels are not elevated enough to point to smoke right now.
