According to the Central Pollution Control Board's (CPCB) daily AQI bulletin, city's index value on Wednesday was 178, reeling under the moderate zone.

Delhi breathed clean air on Wednesday after a gap of 50 days as the air quality was recorded in the 'moderate' category, offering much-needed respite from the high levels of pollution.

However, the city’s air quality remains suboptimal, as an AQI between 201 and 300 is still considered harmful to sensitive groups. The absence of dense fog has allowed sunlight to reach the surface, aiding the scattering of pollutants as the mixing height stayed relatively high.

An AQI between 0 and 50 is considered 'good', 51-100 'satisfactory', 101-200 'moderate', 201-300 'poor', 301-400 'very poor', and 401-500 'severe'. Delhi's air quality has seen consistent improvement this week.

The 24-hour average Air Quality Index (AQI) of the city was recorded at 268 at 4 pm, registering a slight improvement from 280 on Monday.

The improvement in air quality to consistent dry northwesterly winds blowing at around 8 km/h since Saturday has strengthened overnight, reaching up to 15 km/h on Sunday, dispersed pollutants.

Smog enveloped many areas of Delhi on Tuesday, with the air quality index (AQI) staying in the 'poor' category. Several locations showed reduced visibility due to the smog. The Supreme Court refused to relax anti-pollution measures and emphasized better coordination among authorities.

Delhi's air quality improves to 'moderate' category with Air Quality Index at 211, as per CPCB data on Wednesday.

The India Meteorological Department (IMD) said no fog was reported in the national Capital on Wednesday, with the lowest visibility being around 1200 metres

At 8 am, data from multiple monitoring stations showed a significant improvement in AQI compared to the “very poor” category reported last week. According to the CPCB, Major Dhyan Chand Stadium recorded an AQI of 209,
