Union ministry of earth science’s air quality monitoring centre, System of Air Quality and Weather Forecasting and Research (Safar), forecasted that the pollution levels are expected to reduce in the coming days.

“A marginal improvement in ventilation index is forecasted for the next two days and AQI is likely to marginally improve to the lower end of the very poor category in the next two days. AQI is forecasted to marginally deteriorate towards the middle-end of the very poor category on January 31,” the Safar forecast read.
