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 Dehradun: traffic, industry and power plants
Over the last 14 days the air over Dehradun held 1.37 times the region's usual level of nitrogen dioxide (NO₂), #44 of 58 cities.
The strongest NO₂ peak within 35 km was 1.66 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.

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.
