"The latest NASA images show a drastic spurt in crop residue burnings (stubble burnings) in the neighbouring states of Delhi, which has severely affected Delhi's air quality. The stubble plume from north-west regions has become one of the significant factors in adversely affecting Delhi's air quality," said the statement.
"Today, transport-level wind direction is north-westerly, which might increase stubble plume towards Delhi. As per SAFAR-model, the stubble share may touch this year's peak value now," the statement said.
The statement further said that Delhi is going through a bad period with reference to ambient air quality after celebrating one of the cleanest Diwali in the last few years.
"The overall pollution level during the Diwali period in 2019 was found to be better than the past many years. Boundary layer winds speed also helped to flush out the additional load of last night," added the statement.
