While comprehensively reviewing the overall air quality parameters of Delhi-NCR and other aspects, the Sub-Committee observed that the AQI of Delhi has shown significant improvement due to strong surface winds and thunderstorms followed by light rains, being recorded as 179 on May 18 (in ‘moderate’ category), and further, the forecast by IMD/IITM also predicts AQI to mainly remain in ‘moderate’ category in coming days, the statement added.
