Cities we watch, worst to best
The monsoon has nearly gone from Punjab and Haryana, and with it goes the stretch when much of the country breathes its cleanest air of the year. October opens the season everyone argues about: paddy stubble burning across Punjab and Haryana, Diwali, and the temperature inversions that hold everything down. What follows is the same set of decisions, taken again.The rains have nearly gone from Punjab and Haryana. That ends the cleanest few weeks of the year for most of the country. Now come crop fires in Punjab and Haryana, Diwali, and cold air that traps the smoke near the ground. The same choices are made every year.
Where the numbers come from
Live readings come from India's continuous CPCB monitoring network, which is why they exist only where a machine does. Annual satellite estimates close the gap and reach every ward, panchayat and village. Eleven years of CPCB's own daily bulletins sit behind both.Live numbers come from government machines that measure the air. There is a machine only in some places. For everywhere else we use satellite pictures, which give a figure for the whole year rather than for today.
