NCR Air Pollution
It would really be a stupid point if we claim that Diwali don't contribute to the pollution fiasco and our failure to control pollution. It would be more like giving a excuse of your stupidity by comparing it to the others, but i would also like to emphasis on the selective biasing of the people towards Diwali and all the fuzz around social media. Here is an article which talks about the major reasons contributing to the air pollution and yes pollution due to fire crackers contribute significantly to this but air pollution start increase post diwali from October 25th because of change in weather patters.
People now days are more aware of the fact that air around them is polluted. You can verify this by looking at the increase in the sales number of Indoor Air purifier ( 18-25% increase in sales in winter season ) and that is the reason, people have moved away from burning crackers . Here is article which talk about post-diwali AQI of 2018 and 2019 which was 642 in 2018 and 368 in 2019. Though this 2 year AQI don't define what will happen next year, but i think people know that this pollution is going to impact their children a lot and they don't want a bad future for their children's. What is needed is a reform on micro-level making people understand the impact of air pollution just like GOI has done for open defecation.
Diwali happened to be a festival during the start of winter season where temperature start decreasing, moisture content start increase and wind speed near the surface of the air decrease ( obvious as there is very little difference between the surface temperature and high altitude temperature ). We have observed this phenomenon in Bangalore while running a experiment. In the day time, the number of PM10 particles count ( 1 hour average - 3 minute sensing ) was lesser as compared to the night time and the reason behind this was ( as mentioned in the previously was presence of air moisture and warm air near the surface ( Bangalore is not too cold even in winters and thus there is some difference between the air near to the surface and air at 1000 meter height ) which is not the case in the NCR region. I have done similar kind of experiment in Kanpur before Diwali and during Diwali. Below is the graph representing PM2.5 and PM10 values in outskirts of Kanpur in the month of June.
Here is the link to the trail of tweets during my experiment of Air Quality last year in the month of November. I wanted to extend this experiment by deploying more number of static air quality monitor in Kanpur just like Skymet has done now in Delhi i.e. monitoring hyper-local air quality in Delhi and doing analysis along with other factors like Temperature, Humidity and density of vehicles in the vicinity thus reaching a conclusion if peak time impact the air pollution. Here is the link to Skymet android app. This kind of experiment will help the local government to find the sources of pollution and then take measures to reduce it. I am not going to point out possible solution to this problem because i think there are people with far more knowledge and experience but i think, evey individual has to contribute their bit in the fight against the pollution. I have done my bit by saying big NO to crackers from last 3 years and i have plans to do local workshops in Kanpur to raise awareness towards pollution.
Now coming to the reason behind writing a articles on air pollution all of sudden, one friend of mine asked a very valid question that where all this pollution goes. I have some understanding that heavy particles eventually settle down but what about other gaseous pollutants like NO2, SO2, PM1 and PM2.5? I am raising this question to all the experts out there to help me understand what happen to the produced pollution? Does it literally settle down ? We all know the hole in Ozone layer. I read a really interesting article which discussed in detail about how Particulate matter settle down indoor, but i am not sure if that stand true for outdoor.
Link to a online book for those who want to under particulate material in depth ( no i didn't went through it ).

I am contributing my bit to fight against Air pollution and would request all those who are reading this article to spread awareness about Air pollution at their level.
Belated Happy Diwali to all.
