Wind and smoke outlook
At 07:30 IST on 13 Nov, surface winds in Delhi were 3.1 km/h from the south-southeast with a mixing height of 17 m7. Over the last 72 hours, 74.0% of air trajectories passed over the burn belt7.

Fields at risk of burning
Sentinel-2 imagery mapped 2,64,124 harvested fields covering 4,26,526.2 ha across the region26. Unburnt harvested fields include areas in Shafipur and Malikpur in Jhajjar district, and Siwana in Bhiwani district26. Model backtesting over 285 pass pairs shows a modest AUC of 0.61 (95% CI 0.54–0.70, where 0.5 is chance)26.
What satellites missed
Candidate unseen burns cover 0.0 ha, 0.0% of the mapped burn-scar area26. That share is an upper bound: in an audit of 23 candidates, 87.0% were real burns (95% CI 67.9%–95.5%)26.
