Meanwhile, the Commission for Air Quality Management (CAQM) has announced preventive measures to control air pollution across Delhi-NCR ahead of the winter pollution season.

Editorial Analysis
Why This Matters
The rainfall provided temporary relief from high temperatures and pollution in Delhi. At the same time, CAQM's preventive directions highlight the continuing challenge of controlling air pollution across the national capital region during the winter months.
The directions cover Delhi and the NCR districts of Gurugram, Faridabad, Sonipat, Ghaziabad and Gautam Buddha Nagar.
The CAQM has also directed restrictions on dust-generating construction and demolition activities across the National Capital Region during the same period. Specified essential infrastructure projects and critical activities, including those related to railways, metro services, airports, hospitals, water supply, sanitation, national security and defence, are exempted under the directions.
These measures are intended to reduce pollution emissions before the seasonal deterioration in air quality generally experienced across Delhi-NCR during November.
The impact of the rainfall on air quality is expected to be temporary, as pollution levels will continue to depend on weather conditions, local emissions and other seasonal factors.
