Of the 38 monitoring stations that recorded air quality data, only six stations reported levels in the poor category, according to the Central Pollution Control Board (CPCB)

However, a thin layer of smog engulfed the city as the winter set in. As per the India Meteorological Department (IMD), Delhi has recorded a minimum temperature of 9 degrees Celsius today with mist in the air

As per the data of the CPCB, the AQI at Anand Vihar stands at 178 as of 8 am, 194 at Chandani Chowk, 130 at ITO, 152 at Wazirpur, 147 at Okhla Phase 2, 145 at Jawaharlal Nehru Stadium, 164 at Patparganj, 107 at Aya Nagar, 128 at Lodhi Road, 162 at IGI Airport (T3) and 152 at Punjabi Bagh

However, areas such as RK Puram recorded an AQI of 204, Mundka 222, Shadipur 249, Nehru Nagar 247 and Jahangirpuri 206, categorised as 'poor'

An AQI between zero and 50 is considered 'good', 51 and 100 'satisfactory', 101 and 200 'moderate', 201 and 300 'poor', 301 and 400 'very poor', and 401 and 500 'severe'

The city's minimum temperature settled 1.0 notches below normal at 8.5 degrees Celsius, the India Meteorological Department said

It has forecast mainly clear sky during the day while the maximum temperature is expected to hover around 27 degrees Celsius

Delhi's AQI was reeling in 'very severe', 'severe', 'very poor' and 'poor' categories post-Diwali. Residents in the region complained of breathing difficulties and several other medical problems

Increasing AQI in the city led to the implementation of Graded Response Action Plan (GRAP)-IV measures to curb air pollution. Stage IV enforces a ban on the operation of Delhi-registered BS-IV and below diesel-operated medium goods vehicles (MGVs) and heavy goods vehicles (HGVs), except for essential services
