The Commission for Air Quality Management in NCR and Adjoining Areas said on 3 September 2026 that it is in discussions with Punjab and Haryana to improve the measurement of stubble burning fires ahead of the winter pollution season. CAQM chief Rajesh Varma said satellite fire counts from overhead passes may not give the most accurate picture of the extent of farm fires, and that the Commission has asked ISRO to develop a basic ground truthing protocol this year to get a better estimate than fire counts alone. The move is part of CAQM's preparation to manage the sharp seasonal rise in Delhi NCR's air pollution linked to paddy stubble burning in Punjab and Haryana each October and November.
