Delhi Chokes: 'Severe' AQI, Dense Fog, GRAP-IV Curbs Imposed Amid Cold Wave

• Delhi's Air Quality Index (AQI) hit 'severe' at 418, with hotspots like ITO (434) and Rafi Marg (417) reporting even higher levels, triggering GRAP-IV.
• Dense fog reduced visibility, delaying flights at Indira Gandhi International (IGI) Airport and disrupting transport services.
• The pollution crisis escalated over the weekend, marking Delhi's most polluted January day in two years with AQI reaching 440 on Sunday.
• GRAP-IV measures, including bans on construction and vehicle restrictions, were enforced by CAQM after AQI crossed the 400 mark.
• Cold wave conditions persist across North India, with freezing temperatures in Srinagar (-4.7°C) and Mount Abu (-5°C), while Delhi expects moderate fog.

Why It Matters: Delhi faces severe air pollution and dense fog, leading to GRAP-IV curbs and transport disruptions.
