Capital’s air slightly improves on October 18, though the AQI still hovers over the poor category, states data from the Central Pollution Control Board (CPCB). The AQI of Delhi stood at 254, while, the AQI figures for Gurugram and Noida read 273 and 252 respectively, as per CPCB.
However, as per System of Air Quality and Weather Forecasting and Research (SAFAR), the capital’s air quality is likely to be in ‘poor’ to ‘very poor’ category as the instances of stubble burning are on the rise in the neighbouring States of Punjab and Haryana.
SAFAR said that the wind speed seems marginally improving for the next two days which will lead to a relatively better dispersion of pollutants and lightly improved air quality in Delhi. However, the AQI is estimated to remain in the higher end of the ‘poor’ category. “Though fire emission has increased and transport-level wind direction is also favourable, an increase in transport-level wind speed and local Delhi surface winds are likely to maintain the stubble contribution in Delhi PM 2.5 around the same level,” added SAFAR.
