Delhi has experienced its cleanest first half of December since the air quality index (AQI) data was first collected in 2015, with significant improvements in air quality across the capital. According to data from the Central Pollution Control Board (CPCB), Delhi recorded an average AQI of 238 from December 1 to December 15, the lowest ever for the month.

The Central Pollution Control Board (CPCB) has expressed concerns over the feasibility of using cloud seeding as an emergency measure to tackle Delhi’s severe air pollution crisis. Responding to a proposal by IIT Kanpur, the CPCB outlined challenges related to the technique’s effectiveness in winter, citing insufficient moisture in the atmosphere and reliance on pre-existing clouds for artificial rainfall.

Despite a reduction in the contribution from stubble burning, Delhi's air quality continued to remain in the "very poor" category, with the Air Quality Index (AQI) recorded at 387 at 12 PM on Friday, dangerously close to the "severe" range. The AQI had registered 390 at 11 AM, and 377 as the 24-hour average on Thursday. The high pollution levels have led to poor visibility and widespread health concerns for the residents of the national capital.

Delhi's air quality remained at hazardous levels on Wednesday, as the city continued to face a "very poor" air quality index (AQI) for the fourth consecutive day. Calm winds and a layer of shallow fog contributed to the ongoing air pollution, with visibility dipping to around 800 meters early in the morning. The shallow fog, which was recorded for a second day, has exacerbated the situation, making it difficult for pollutants to disperse.
