Amid the severe cold conditions in many parts of north-India, the air pollution in the national capital remained in the 'very poor' category with an overall air quality index (AQI) stood at 339.
The System of Air Quality and Weather Forecasting And Research (SAFAR) stated, "Surface winds west southwesterly and moderate. Marginal decrease in ventilation index is forecasted, AQI is likely to marginally deteriorate to the middle-end of very poor on January 25 and 26. The middle to the higher end of the very poor category is forecasted for January 27."
An AQI between 0-50 is marked good, 51-100 is satisfactory, 101- 200 is moderate, 201- 300 is poor, 301-400 is very poor and 401-500 is considered severe.
Moderate wind speed which leads to moderate dispersion, stubble burning could be among the few reasons which lead to deterioration of AQI, the SAFAR stated.
