Central Pollution Control Board (CPCB) data showed that on Tuesday the overall AQI level in Delhi was 175, also in the “moderate” category.
India Meteorological Department (IMD) scientists said that the improvement in air quality was a result of increased wind speeds and ventilation levels. However, the forecast said that from Thursday there is a possibility of slight deterioration.
