What was the minimum temperature recorded in Delhi on the night of November 6, 2025, marking the coldest night of the season so far?
12.7 degrees CelsiusOn the night of November 6, 2025, Delhi recorded its coldest night of the season with the mercury dipping to 12.7 degrees Celsius, which was the first time that winter the temperature fell below 15 degrees. According to the India Meteorological Department (IMD), this reading was around three degrees below the normal for this time of year. The sharp decline followed a reading of 18.4 degrees the previous night. Officials attributed this sudden chill to cold north-westerly winds flowing into the region after fresh snowfall in the western Himalayas, combined with clear skies that enhanced radiational cooling.

According to the Central Pollution Control Board (CPCB), what was Delhi’s 24-hour average Air Quality Index (AQI) on November 6, 2025?
311Delhi’s 24-hour average AQI on November 6, 2025, stood at 311, placing the city in the 'very poor' or 'red zone' category as per CPCB data. This marked a deterioration from the previous day when the AQI was 202, due to favorable wind conditions dispersing pollutants. Stubble burning was identified as a major contributor, with satellite data detecting significant fire incidents in Punjab, Haryana, and Uttar Pradesh. The Decision Support System forecasted that stubble burning’s contribution to PM2.5 would rise further in the coming days. The poor air quality prompted renewed enforcement of the Graded Response Action Plan (GRAP).
Question 8 Nov 07, 2025

Which pollutant source contributed the highest percentage to Delhi’s PM2.5 levels on November 7, 2025, according to the Decision Support System (DSS)?
Stubble burningOn November 7, 2025, stubble burning was projected to contribute 36.9% to Delhi’s PM2.5 levels, making it the largest single source that day. This was a sharp increase from just 1.2% on November 5. The rise was linked to 94 fire incidents detected in Punjab alone on the previous day, along with others in Haryana and Uttar Pradesh. Transport emerged as the second-highest contributor but with a much lower share (11.2%). Authorities anticipated continued poor air quality between November 6 and 8 due to these emissions and low wind speeds.
Question 9 Nov 07, 2025

How many motorists were penalized by the Delhi Traffic Police for driving without a valid Pollution Under Control (PUC) certificate as of October 2025?
Over 4.87 lakhAs of October 2025, the Delhi Traffic Police penalized over 4.87 lakh motorists for driving without a valid PUC certificate, marking a 20% increase compared to the same period in 2024. This intensified enforcement is part of efforts to curb vehicular emissions amid persistently poor air quality. Additionally, more than 8.87 lakh challans were issued for PUC-related violations, and special checks were conducted at city entry points to stop non-compliant vehicles. Only about 10% of violators had paid their fines, indicating challenges in enforcement compliance.
Question 10 Nov 07, 2025

What is the minimum number of anti-smog guns mandated for buildings in Delhi with a built-up area of less than 10,000 square metres?
ThreeAs per Delhi government norms, buildings with a built-up area of less than 10,000 square metres must install a minimum of three anti-smog guns. The mandate applies to all private and government buildings of G+5 height or more, with a compliance deadline of November 29, 2025. While 91 buildings had already installed such devices by early November, environmentalists criticized the measure as only a temporary fix, arguing that anti-smog guns only reduce PM10 levels locally and fail to address root pollution sources like vehicular emissions or industrial discharge.
