Air quality in Tadpatri right now
Right now the modelled US Air Quality Index for Tadpatri, Andhra Pradesh, India is 97, which falls in the "Moderate" band (up to 100). Acceptable for most people. Unusually sensitive people should consider shortening long or heavy exertion outdoors.
The index is driven mainly by PM2.5, whose own sub-index is 97. 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 35 µg/m³, 2.3 times the WHO 24-hour guideline of 15 µg/m³; PM10 is 36 µg/m³ against a guideline of 45; ozone is 71 µg/m³ (below the WHO 8-hour level of 100); nitrogen dioxide is 10 µg/m³ (below the 24-hour guideline of 25).
Also this hour: UV index 0.8, carbon monoxide 349 µg/m³.
NASA FIRMS shows 36 fire hotspots within 300 km in the last day (nearest about 13 km), but particle levels are not elevated enough to point to smoke right now.
