Ambala Haryana

1,766 candidate unseen burns covering 2,350 ha in 455 villages, in the 30 days of passes up to 12 Nov 2026. None of its 1,903 harvested fields ranks in the top tenth for the next burn.

Candidate unseen burns are not confirmed fires: their audit precision 87% (95% CI 68–⁠96%, n = 23), so every count and area of them here is an upper bound.

The top tenth comes from a burn-risk ranking that is modest in its backtest (AUC 0.640, 95% CI 0.595–⁠0.693; 0.5 is chance): a rank says where to look first, not the chance that a field will burn.

Watchlist: harvested fields by burn-risk rank (none in the top tenth)

Harvested fields whose straw was still lying on the latest clear pass, grouped by village and ordered by the burn-risk run of 13 Nov, 17:23 IST.

Modest ranking

In this season's backtest, fields in the top tenth of their pass burnt by the next clear pass 1.61 times as often as the average field (95% CI 1.28-2.04): 20.1% against 12.5%. The backtest could order past fields only by burning nearby and last season's fires: the time since harvest and the rain cannot be reconstructed for past passes. Checked over all 387 pass pairs, the ranking is modest (AUC 0.640, 95% CI 0.595-0.693; 0.5 is chance). A rank says where to look first; it is not the chance that a field will burn.

How to read this brief

Candidate unseen burns are Sentinel-2 burn scars that no NASA FIRMS fire detection explains. They are candidates, not confirmed fires: in a hand audit of 23 of them, 87% were real burns (95% CI 68%-96%), so every count and area of them here is an upper bound.
The window is the 30 days of Sentinel-2 passes up to the newest one in the data (2026-11-12), not up to today: Sentinel-2 sees a field only every few days, and its passes are processed once a day.
Each village's point is its largest candidate unseen burn, so its map link leads to the burnt field itself. Village names are the nearest census village within 3 km of a scar; scars with no village that close are listed by sub-district, without a name.
The watchlist orders harvested fields whose straw was still lying on the latest clear pass by the burn-risk run of 2026-11-13 17:23 IST: villages with fields in the run's top tenth first, then the others by their best-ranked field, so a district with no field in the top tenth still gets a list. In this season's backtest, fields in the top tenth of their pass burnt by the next clear pass 1.61 times as often as the average field (95% CI 1.28-2.04): 20.1% against 12.5%. The backtest could order past fields only by burning nearby and last season's fires: the time since harvest and the rain cannot be reconstructed for past passes. Checked over all 387 pass pairs, the ranking is modest (AUC 0.640, 95% CI 0.595-0.693; 0.5 is chance). A rank says where to look first; it is not the chance that a field will burn.
These lists say where to look, not who burnt: a satellite flag needs a visit on the ground before any action, and the brief names villages only, never people.
