"However, now wind speed has picked up slightly which may lead to slight improvement in the pollution level till evening today. Since moderate cold wave to severe cold wave conditions are prevailing over major parts of north India surrounding Delhi, appreciable improvement is not expected," it said.

On Friday, the Central Pollution Control Board data showed the overall air quality index (AQI) at the ‘very poor’ level of 394, while the Centre-run System of Air Quality and Weather Forecasting (SAFAR) showed an AQI of 372, which falls in the ‘very poor’ category.

Delhi is reeling under the menace of air pollution for the past couple of years. The region faced a major air quality crisis last year when severe pollution level forced the shutdown of schools and colleges. In 2016, the government tried to explore the possibility of cloud seeding for artificial rain but the plan never worked out.  

An AQI between 100 to 200 comes under ‘moderate’ category, 201 and 300 is considered ‘poor’, 301 and 400 ‘very poor’ while between 401 and 500 ‘severe’. The overall PM2.5 (fine particulate matter in the air with a diameter of less than 2.5 micrometre) level was recorded at 143 and the PM10 (fine particulate matter in the air with a diameter of less than 10 micrometre) level at 253, according to SAFAR.
