First discovered ammonia gas in the troposphere

The new discovery of ammonia on the lowest level of the atmosphere will be very supportive in building a global climate change model.

As a major waste product from livestock and fertilizer industry, ammonia (NH ₃ ) was discovered in the upper part of the troposphere in China and India. These are the two regions where population and economy are skyrocketing in recent years.

The lowest floor of the troposphere has been penetrated.

The troposphere has a height of 7-20 km from the sea surface, accounting for about 80% of the total volume of the atmosphere. This is where most of the weather phenomena on Earth happen.

The research group from the Karlsruhe Institute of Technology, the Federal Republic of Germany has recorded satellite data from 2006 - 2012 and calculated the average once every 3 months. The team discovered the presence of ammonia - a compound between hydrogen and nitrogen at a height of 12-15km above the monsoon region of Asia.

Asia region monsoon.

The highest concentration measured was 33 pptv (33 parts per trillion) in North India and Southeast Asia.

"We think this is the first evidence of the occurrence of ammonia on the upper floor of the convection (about 10 km above sea level). The area and the detection time is the monsoon season of Asia " - the group said.

The findings showed that ammonia emissions from agricultural production existed and penetrated the troposphere under monsoon winds.

Distribution of ammonia in the atmosphere.

"According to what is observed, ammonia is not completely dissolved in the atmosphere during the monsoon cycle, so its remnants have the opportunity to penetrate the troposphere in concentration areas. High, " adds research leader Michael Hopfner.

Because traces of ammonia were found in the troposphere of the monsoon Asian region, it is doubtful that agricultural emissions themselves formed aerosols on the troposphere.

Aerosols (Aerosol, polluted fog) - include microscopic matter particles covered by droplets of air in the air that often converge into the form of rain clouds. When microscopic matter particles in the form of aerosols accumulate in the form of clouds, they also change the properties of the surrounding clouds.

Aerosol - Aerosol - is a colloidal system of solid particles or other liquid, air or gas droplets.

According to NASA's explanation, Aerosol can change the size of solid dust clouds and also change the absorption and diffuse light of clouds, leading to the phenomenon of fog, red sunset, Red Dawn. As far as we know, when the ammonia released from agriculture reaches a high concentration of pollution, not only is an ecological part of that area affected but also the structure and properties of the cloud system. located in the upper atmosphere will also change.

Ammonia is not the only waste gas found in the atmosphere. Recently a hot hydrogen atom has been found in the upper atmosphere and, according to what we know, is a bad sign.

This new discovery of ammonia will greatly support the building of a global climate change model. The group will proceed to build an existential model of ammonia on the troposphere in India and China next year.
