Air quality in Maicao right now
Right now the modelled US Air Quality Index for Maicao, La Guajira Department, Colombia is 45, 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 45. 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 2.8 µg/m³, within the WHO 24-hour guideline of 15 µg/m³; PM10 is 3 µg/m³ against a guideline of 45; ozone is 54 µg/m³ (below the WHO 8-hour level of 100); nitrogen dioxide is 3.8 µg/m³ (below the 24-hour guideline of 25).
Also this hour: carbon monoxide 160 µg/m³.
NASA FIRMS shows 30 fire hotspots within 300 km in the last day (nearest about 60 km), but particle levels are not elevated enough to point to smoke right now.
