GRAP-IV Revoked in Delhi as Air Quality Shows Marginal Improvement

• The Commission for Air Quality Management (CAQM) revoked GRAP-IV restrictions in Delhi due to a marginal improvement in air quality.
• CPCB data showed a slight improvement from Monday's 'severe' AQI of 418, though many areas remained in the 'severe' category.
• Anand Vihar, Ashok Vihar, Wazirpur, Punjabi Bagh, RK Puram, Bawana, ITO, Chandni Chowk, and Dwarka Sector 8 recorded AQI above 412.
• GRAP-IV measures are invoked when the AQI exceeds 450, classified as 'Severe'.
• Forecasts from IMD and IITM predict Delhi's average AQI will remain in the 'very poor' category in the coming days, with agencies instructed to maintain vigilance.

Why It Matters: Delhi's GRAP-IV restrictions are lifted due to slight air quality improvement, but 'very poor' conditions persist.
