New Delhi, Dec 11 (NationPress) The air quality in Delhi has remained entrenched in the poor category for the third consecutive day as of Thursday morning. According to the latest data from the Central Pollution Control Board (CPCB), the overall air quality index (AQI) has further dipped to 285, just shy of the 301 mark that would classify the conditions as very poor.
As of 7 a.m., at least ten monitoring stations throughout the city reported AQI levels exceeding 300, which categorizes them as very poor. Notable figures include Anand Vihar at 300, Ashok Vihar at 328, Chandni Chowk at 305, and ITO at 309.
In Noida, the overall AQI registered at 294 (Poor), with sector-specific readings ranging from 246 to 331. Greater Noida's Knowledge Parks 3 and 5 recorded AQI values of 235 and 331, respectively.
On Wednesday, the city’s 24-hour average AQI was noted at 259, reflecting a minor improvement from Tuesday's 282. After nine straight days of air quality plunging into the very poor zone, some relief was observed on Tuesday, attributed to stronger daytime winds on Wednesday that maintained conditions within the poor category for the second day.
The CPCB defines AQI ranges as follows: 0-50 (Good), 51-100 (Satisfactory), 101-200 (Moderate), 201-300 (Poor), 301-400 (Very Poor), and 401-500 (Severe).
In addition to air quality fluctuations, the city also experienced a slight drop in temperatures. Delhi recorded a minimum temperature of 10 degrees Celsius on Wednesday, which is 0.4 degrees below the seasonal average, while the maximum temperature reached 25.2 degrees Celsius, also 0.4 degrees below normal.
The India Meteorological Department (IMD) forecasts that minimum temperatures across northwest India, including Delhi and surrounding NCR cities like Noida, Gurugram, and Faridabad, are expected to remain stable for the next two days before rising by 2 to 4 degrees Celsius over the subsequent three days, with conditions stabilizing afterward.
For Thursday, the IMD anticipates partly foggy conditions, with minimum temperatures expected around 8 degrees Celsius and maximum temperatures near 24 degrees Celsius.
