New Delhi: Delhi’s air quality again fell in the ‘very poor’ category on Thursday (November 25) after seeing a slight improvement a day earlier. According to the System of Air Quality and Weather Forecasting and Research (SAFAR), the overall air quality index (AQI) stands at 330 today.

“AQI today indicates ‘very poor’ category. Local surface winds are relatively low for next 3 days reducing the dispersion of pollutants leading to deterioration in air quality but air quality in high end of ‘very poor’ category is likely to be in the ‘poor’ category for the next two days,” Safar said in a bulletin. It further said that the local surface winds are likely to increase on November 27 resulting in an improvement in the air quality but is expected to remain in the ‘very poor’ category.

“With the onset of winter local weather is likely to dominate in determining air quality,” it added. Gurugram and Noida recorded an AQI of 276 and 123 in the “poor” and “severe” categories, respectively.

AQI between zero and 50 is ‘good’, 51 and 100 ‘satisfactory’, 101 and 200 ‘moderate’, 201 and 300 ‘poor’, 301 and 400 ‘very poor’ and 401 and 500 ‘very poor’ considered serious.
