5Why did official and private agencies report different AQI readings for Delhi?⌵

The reported readings differed amid questions about monitoring network coverage and data availability, as well as variations in measurement parameters and averaging methods.

"Partly cloudy sky. Moderate fog at most places in the morning hours. The maximum and minimum temperatures over Delhi are likely to be in the range of 27°C to 29°C and 14°C to 16°C, respectively. The minimum temperature will be near normal (-1.5°C to 1.5°C) at most places, and the maximum temperatures will be below normal (-1.6°C to -3.0°C) at most places over Delhi," the IMD said.

Isolated heavy rainfall is also likely over the Andaman & Nicobar Islands during 10-14 November and over Nagaland, Manipur, Mizoram, and Tripura on 11 November, said the IMD.

Delhi Air quality

Delhi's air quality index remained in the "very poor" category at 311 early Tuesday, according to the CQAM. It was recorded at 344 at 4 pm on Monday, compared with 376 reported at the corresponding time on Diwali day (Sunday).

Delhi recorded its most polluted Diwali in five years. However, the severity was likely worse than official figures showed, as several monitoring stations went offline on Sunday night during the peak period of firecracker use in the Capital, according to PTI.

AQI (air quality index) readings from private agencies did, in fact, paint a much more unpleasant picture than the official figures, with most parts of Delhi-NCR reporting extremely hazardous air pollution levels, leading experts to cast doubt on government data.

Meanwhile, AQI recorded an air quality reading of 637 in Delhi on Monday morning, classifying it as "hazardous". The platform also reported that the city's AQI had peaked at 2,283 after Diwali.

The differences in readings brought the monitoring network, data availability and variations in measurement parameters and averaging methods used by government and private agencies into focus - not for the first time, though.
