Greenhouse Gases rising pollution, temperature blowing up
Nainital: Due to global warming and emission of Greenhouse Gases, the situation of air pollution in Central Himalayas and North India is getting worse. The latest data from the Aryabhatta Observational Science Research Institute (ARIES) confirms this fact. These figures are worrying. These figures are worrying and may result in bad weather in future.
This is the rate of emission of green house gases
In the last 16 years, the amount of carbon dioxide has increased by 25 ppm (part per million), sulfur fluoride 6 by 10.5 ppt (part per trillion) and nitrogen by 12 ppb (part per billion), whereas in the last two decades there has been a significant increase. There has been a jump of about .2 degree Celsius in the average temperature. This may result in bad weather in future.
Ares is keeping an eye on radar
Atmospheric scientist of Aryabhatta Observational Science Research Institute (ARIES) Dr. Manish Naja told that due to global warming, the climate is changing rapidly. The biggest reason is the increasing emission of green house gases. State-of-the-art facility like ST radar is present in ARIES to monitor air pollution, due to which weather and air pollution are monitored from ground to sky.
Increase in emissions of house gases
According to the data available at present, the amount of carbon dioxide was 380 parts per million (ppm) in 2006, which has increased to 405. Whereas in 2006, the amount of sulfur fluoride 6 has increased from 10.5 parts per trillion (ppt) to 21. There has been a two-fold increase in this. Apart from this, the amount of nitrogen has increased from 320 to 332 parts per billion (ppb).
The continuous increase in the amount of green gases in the atmosphere is not good, which is increasing the temperature. This average increase has occurred in the entire North India region in the Central Himalayan region. Which has also affected the highest temperature of the day. The average extreme temperature has increased by .1 to .2 degree Celsius in the last two decades.
Vehicle and electricity is a big reason
The continuous growth of vehicles along with the continuous irregular increase in air-conditioned equipment is increasing the amount of carbon dioxide. Coal used to make electricity is the reason, as well as carbon dioxide released in large quantities from the air condition. This polluting gas cannot be reduced without curbing the uncontrolled growth of vehicles. Stubble is not a big reason for increasing air pollution in Delhi NCR.
ARIES begins study at low altitude
It is easy to study through satellites and models up to an area with a height of 6 to 20 km from the ground to the sky, but observation up to six km cannot be done through these facilities. ARIES has started this work. It is very important to keep an eye on the atmosphere of the low altitude area. Several conclusions can be drawn from the data obtained from this study. At this height, data on circulation of moist air rising from the ground and dry air coming down can be obtained.
Five ST radars will keep an eye on country’s pollution
Dr. Manish Naja said that the scientists operating all the five ST radars of the country are going to participate in the four-day meeting which is going to start in Indore from December 1. The meeting will discuss about better monitoring of the air pollution situation. At present there are five ST radars installed in the country. Apart from Nainital, Aries is present in Triputi, Cochin, Kolkata and Guwahati. In this meeting, issues related to weather and environment will be discussed along with the air pollution situation and prevention in many parts of the country.
What are Greenhouse Gases
Greenhouse gases, also known as GHGs. These gases are mainly responsible for the rise in temperature. If we look at the 6 major greenhouse gases present in the atmosphere, they include carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF 6). These gases absorb and radiate radiation within the thermal infrared range, which is responsible for the greenhouse effect.
