Delhi’s air quality improves, GRAP-3 revoked
While temperatures continue to drop down in Delhi and NCR, the Central Pollution Control Board (CPCB) reported that the AQI had been lingering in the ‘inferior’ category for the past week.
On Monday, the AQI was recorded at 335 in the “very poor” category.
Additionally, the Commission for Air Quality Management (CAQM) on Sunday revoked curbs under Stage 3 of the Graded Response Action Plan (GRAP) in Delhi-NCR after the region witnessed a dip in air pollution levels owing to favourable meteorological conditions, especially improved wind speed.
However, restrictions under Stage 1 and Stage 2 of GRAP remain in place across Delhi-NCR.
An AQI between 0 and 50 is considered ‘good’, 51-100 ‘satisfactory’, 101-200 ‘moderate’, 201-300 ‘poor’, 301-400 ‘very poor’, and 401-500 ‘severe’.
Dense fog in Delhi
Meanwhile, heavy and dense fog, which enveloped Delhi during the early hours of Tuesday, drastically reduced visibility to 150 meters and delayed 25 trains.
The IMD reported that the minimum visibility was recorded at 500 meters at Safdarjung, while at Palam, it was as low as 150 meters between 5 and 5:30 am, before improving to 700 meters by 8:30 am.
