Bathinda: The Center for Science and the Environment (CSE) has predicted that this winter might get a very severe peak in fog when compared to previous years.
This was concluded after CSE analyzed the air quality trend in Delhi and the National Capital Region (NCR), in addition to the larger Indo-Gangetic (IGP) region.
“This winter, we might get a severe peak in smog; the agricultural fire count might be more concentrated because of the delayed effect of this rain.
To fight this, the action must be improved immediately,” said Avical Somvanshi, program manager in the data lab analytics Urban in CSE.
Usually, the first phase of the fog is triggered by a slight burning steep.
This year’s agricultural fire contribution began around 10 October, at the same time in 2018 and 2020.
This year’s peak contribution has so far been registered on October 16, when 14% PM2.5 Delhi is associated with stump fire smoke.
Heavy rain on the following days washing the first buildup this season.
The smoke season generally peaked around the peak of October and November, with contributions soaring to more than 40% on the worst days, Somvanshi said.
By 2020, during the fire combustion season October 1 – November 29, an average of 12.2% per day PM2.5 PM2.5 Delhi came from the smoke of agricultural shots.
This is much higher than in previous years.
In 2019, the contribution reached 8.9% per day, while it was 10.9% per day in 2018.
Agricultural fire count during the pre-winter season 2021 was less than half of the number recorded last year.
The lower count, as reported by satellite imagery, can also be caused by an increase in cloud cover which inhibits fire spots by satellites.
However, the amount of fire is lower during pre-winter correlates well with lower pollution levels in Delhi-NCR.
Tracking all 67 cities monitored in the Indo Gangetic area make it very clear that air quality goes down to the ‘poor’ and ‘worse’ category as a monsoon retreat.
For most of the North Plains from Punjab to the center of Uttar Pradesh, the early days of poor air quality are almost synchronized perfectly.
The East Plain witnessed the emergence of pollution almost three four weeks later.
It is interesting to note that air cleaned in Punjab is far earlier than in all IGP, while pollution remains longer in NCR and side by side with the West, the research said.
