Delhi-NCR recorded its air quality in the very poor category on Wednesday morning and no major improvement is likely until Sunday, authorities said. The minimum temperature in the capital dropped to 9.6 degrees Celsius, three notches below normal and the lowest this season so far. The maximum is likely to settle around 27 degrees Celsius, the India Meteorological Department said.
The city recorded its air quality index at 389 at 9 am. It had slipped into the severe zone on Tuesday and was recorded at 403 at 4 pm. Air quality index in Faridabad (350), Ghaziabad (368), Greater Noida (358), Gurugram (354) and Noida (369) also recorded their air quality in very poor category.
V K Soni of the IMD on Tuesday told the Commission for Air Quality Management (CAQM) that lower ventilation index due to low temperatures and calm wind conditions is predicted between Wednesday and Sunday, which is unfavourable for dispersion of pollutants. The air quality is likely to improve Sunday onwards due to relatively strong winds, he said.
The Ministry of Earth Sciences' air quality monitor SAFAR has said the intrusion of stubble burning-related pollutants into Delhi is not likely on Wednesday and Thursday as the transport level wind direction is easterly.
Ahead of a Supreme Court hearing on the air pollution issue, the CAQM late Tuesday night directed that schools, colleges and educational institutions in the National Capital Region will remain closed until further orders, allowing only online mode of education.
