Patna's air today: where the smoke is coming from
Patna's smoke report
Right now the wind over Patna blows from the east at 18 km/h (weather model, 30 October, 08:15 IST). Satellites saw no fires within 250 km of Patna in the 24 hours to 30 October, 04:18 IST. That doesn't measure what is in today's air: haze also comes from the city's traffic, industry, brick kilns, burning rubbish and dust.

Map of the fires around the city, last 24 hours
Each dot is one fire a NASA satellite saw. Red dots are upwind, in the direction the wind is coming from, so their smoke is the likeliest to be reaching the city now; grey dots are in other directions. The moving lines show the wind blowing towards the city. Tap a dot for the village and the time.

within 250 km within 50 km
A fire spot is one fire seen on a day, however many satellites saw it (Pakistan-time days). The archive runs every day from 1 October 2026; before that it holds only the October-November seasons.
NO₂ pollution in Patna: traffic, industry and power plants
Over the last 14 days the air over Patna held 1.25 times the region's usual level of nitrogen dioxide (NO₂), #50 of 58 cities.
The strongest NO₂ peak within 35 km was 1.54 times the usual level, in the city itself, the pattern of a city's traffic.
From Sentinel-5P's TROPOMI instrument via NASA's GIBS tiles, which publish NO₂ as colour bands: a level here is good to about one band. NO₂ in big cities comes mostly from vehicle engines; peaks are named after what is nearby, which suggests a source but doesn't measure one. NO₂ window 15 October to 28 October 2026.
Brick kilns
999 brick kilns stand within 50 km of Patna.
Landfills
Satellites and aircraft have measured methane rising from Ramanchak Bairiya Landfill, 5 km from the centre, 4 times, about 779 kg an hour. That puts it #19 of the 58 measured landfills in Pakistan and India.

Fires around Patna this season compared with past years
Fire spots within 250 km of Patna from 1 October to 29 October, each year. These count Suomi NPP alone, so every year is measured by the same instrument and the years compare fairly (the 30-day chart above counts all five satellites, three VIIRS and two MODIS, so its numbers are higher).

Upwind is a guide, not proof: smoke can travel further than 250 km, the wind turns during the day, and satellites can't see fires under cloud. A fire spot is one fire, about 375 m across, however many satellites saw it. Fires: NASA FIRMS (VIIRS and MODIS). Wind: Open-Meteo's weather model. Air: Copernicus CAMS model estimates, which read low in winter.
