Air quality in Morogoro right now
Right now the modelled US Air Quality Index for Morogoro, Tanzania is 49, 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 49. 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 12 µg/m³, within the WHO 24-hour guideline of 15 µg/m³; PM10 is 13 µg/m³ against a guideline of 45; ozone is 9 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 196 µg/m³.
NASA FIRMS shows 648 fire hotspots within 300 km in the last day (nearest about 24 km), but particle levels are not elevated enough to point to smoke right now.
