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.

NO₂ pollution in Ranchi: traffic, industry and power plants

Over the last 14 days the air over Ranchi held 1.4 times the region's usual level of nitrogen dioxide (NO₂), #43 of 58 cities.

1×30 September: 0.97×1 October: 1×2 October: 0.95×5 October: 1.01×8 October: 0.96×11 October: 1.08×13 October: 1.1×16 October: 1.16×19 October: 1.2×22 October: 1.34×25 October: 1.34×27 October: 1.3×28 October: 1.4×30 September28 October

The strongest NO₂ peak within 35 km was 2.52 times the usual level, 26 km from the city centre, near an industrial estate (Patratu Thermal Power Station).

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.

Fires around Ranchi this season compared with past years

Fire spots within 250 km of Ranchi 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).

Fires up to 30 October, 04:18 IST. This page updates every 15 minutes. 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.
