Based on data and images from the National Aeronautics and Space Administration (NASA), the state of burning of stubble in the fields of Punjab can be understood. NASA has been studying the impact of stubble burning on air quality for the past few years.
A dot on this map of Punjab on October 25, 2019 shows a field fire. It changes every year. The points representing field fires on October 25, 2020 will remain the same.
A sample image taken on the same dates in 2021, 2022, 2023 shows the same points. The NASA image shows a large area with red dots. It shows incidents of stubble burning in the fields of Punjab.
From 2012 till now, except in 2016, stubble was burnt in all the fields of Punjab. But if you look at the pattern till 2023, the statistics show that Punjab has the lowest level of stubble burning since 2012.
Hiren Jethwa, senior research scientist at Morgan State University NASA Goddard Space Flight Center, told NDTV, “I was surprised to see that Punjab and Haryana have the lowest incidence of fires. We have never seen such a low trend of stubble burning in fields. Before.” “Haryana and Punjab seem to have had heavy rains this July and August, resulting in the destruction of some crops.”
The scientist said, “I am a little afraid that the incidents (of burning steps) have been delayed. No big fire has been seen so far. It is likely to happen in the next two weeks.”
Delhi’s air quality (AQI) was recorded in the “poor” category for the third consecutive day on Wednesday, according to monitoring agencies. There is no scope for major improvement in Delhi’s AQI in the next few days. The city’s average air quality index (AQI) was 238 at 10 am on Wednesday. It reached 220 at 4 pm on Tuesday.
Ghaziabad, adjacent to Delhi, had an average AQI of 196. While the AQI was recorded at 258 in Faridabad, 176 in Gurugram, 200 in Noida and 248 in Greater Noida.
According to the Center Air Quality Early Warning System for Delhi, the city’s air quality is likely to remain between the “poor” and “very poor” categories in the next four to five days.
Let us tell you that AQI between zero and 50 is good, AQI between 51 and 100 is satisfactory, AQI between 101 and 200 is moderate, AQI between 201 and 300 is bad, AQI between 301 and 400 is very poor. is between and 401 AQI. and 500 is considered severe.
Delhi’s air quality on Sunday became “very poor” for the first time since May. The main reason for this was the drop in temperature and wind speed, which led to the accumulation of pollutants.
