Air quality in Shahrisabz right now
Right now the modelled US Air Quality Index for Shahrisabz, Qashqadaryo, Uzbekistan is 48, 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 48. 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 9.5 µg/m³, within the WHO 24-hour guideline of 15 µg/m³; PM10 is 10 µg/m³ against a guideline of 45; ozone is 71 µg/m³ (below the WHO 8-hour level of 100); nitrogen dioxide is 11 µg/m³ (below the 24-hour guideline of 25).
Also this hour: carbon monoxide 222 µg/m³.
NASA FIRMS shows 35 fire hotspots within 300 km in the last day (nearest about 97 km), but particle levels are not elevated enough to point to smoke right now.
