Air quality in Samarkand right now
Right now the modelled US Air Quality Index for Samarkand, Samarqand Region, Uzbekistan is 50, 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 50. 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 17 µg/m³, 1.1 times the WHO 24-hour guideline of 15 µg/m³; PM10 is 17 µg/m³ against a guideline of 45; ozone is 33 µg/m³ (below the WHO 8-hour level of 100); nitrogen dioxide is 19 µg/m³ (below the 24-hour guideline of 25).
Also this hour: carbon monoxide 185 µg/m³.
NASA FIRMS shows 62 fire hotspots within 300 km in the last day (nearest about 51 km), but particle levels are not elevated enough to point to smoke right now.

With the AQI at 50, there is no need for sensitive groups to change plans. People with asthma should still carry their reliever inhaler as usual.
