Burning stubble blaming Diwali - The NCR pollution mayhem.

Every year arou Diwali the farmers start burning stubble in their field starting around two three days to a week before diwali. 
The Diwali night raises the pollution temporary but the remaining stubble are burnt around Diwali and the next day onward upto a week or two later.

End result - a thick smoke travels all the way to NCR when wind blows eastwards and towards Lahore when the winds blow west causing thick smog in the early week of November in Delhi NCR, Lahore and both side blame it on Diwali whereas the satellite imagery and wind pattern analysis tells a different story.

I have the data from Lahore and Delhi both, Diwali ends in a day but the smog stays a week or more afterwards due to the stubble burnings. 
This year again the problem is evident and Diwali is being sighted as the reason whereas stubble burning in Pakistani punjab and Indian punjab are the real reason.
The following Heat signature image shows fires burning in punjab on 2nd November 2025 around 7 pm IST , the wind was blowing towards Delhi NCR, making it a possibility that 3rd november morning will be heavy smog morning in Delhi NCR, I.e , four to five hours from now.


following images shows the nights from of Diwali 20th october 2025 onwards , notice the amount of heat signatures increasing and peaking on 2nd november 2025. The heat signature and smog of 2nd november night are much much higher than 20th october 2025 night.
The following satellite image clearely shows where the smog originates in Pakistan but still the fake scientist in media will point at Diwali which took place ten days back.

Folloing is raw data of Smog reports for Delhi NCR and Lahore from 2022 to 2025:

Of Smog, Odd Even and Delhi


Every year in the month of October and November Delhi NCR and areas surrounding Punjab experiences smog, or a fog which is majorly smoke.

The Delhi government has been trying various "Tricks" to contain and bring down the effect by introducing not so citizen friendly initiatives like Odd- Even , heavy fines on BS4 vehicles, reduction of diesel fuel vehicles validity etc.

All this while the only relevant question is forgotten, i.e., why the same amount of vehicles don't cause smog in even colder months ? A casual hint about stubble burning is tossed but nothing is done to legally stop it as much legality and cane dangling is done for the Diwali crackers.

Irrespective of the absence of concrete emidsion data it is a known fact that this phenomenon is caused by stubble burning as it directly contributes to smoke in the smog equation.

Last week while discussing the problem with an ex colleague I wondered how much of the smoke is actually generated and is there a way to actually determine the role it has on the smog issue.

This thought process took me to the Arial imagery but since not many people can discriminate between smoke and clouds in the satellite images, I decided to look for infra emission layers as they are very reliable markers of above average heat and fires.

To my amazement the resultant visualisation closely  followed the smog phenomenon, proving beyond doubt that the Odd-even restrictions are merely punishing the victim. The solution can't even start to formulate until the central government makes burning of stubble illegal since carbon emission is responsibllity of the country, thankfully no global environment agency has pointed a fingure at this yet.

Attached are the images with the high infra radiance layers (Shown as orange spots) drwan over  Delhi, Haryana and Punjab for 8th September 2023, 8th October 2023and 8th November 2023.
It is very clear that the amount of radiation closely follows the amount of smog and the air quality index.

In light of these findings it's very clear that odd even can't solve this problem at all. It is upto the people of Delhi NCR, and the areas this phenomenon causes unbearable living conditions, to approach the government / legal system so that this indirect violence and torture is addressed for good.
