The strange Indian atmosphere seen from space, what happens?

Recently, satellite images of the world atmosphere show strange things in the sky of India in particular and South Asian countries in general.

According to the BBC, the Sentinel-5P satellite recently sent to Earth an image of the global atmosphere, notably the distribution of formaldehyde molecules - a colorless gas in nature due to agricultural activities of human waste.

In the chart, India is the most atmospheric country in the world. Other regions also concentrate large amounts of formaldehyde in Central Africa, Central America, East Asia and Southeast Asia.

These are all major agricultural operations in the world. Formaldehyde sources depend on the region, but about 50-80% of formaldehyde comes from plants.

India alone has hundreds of fires and coal fires each year that increase the amount of formaldehyde on the atmosphere.

In addition, the Himalayas towering north of India made winds from the Indian Ocean impossible to take formaldehyde molecules away, so they kept accumulating in the south of the mountain range.

Formaldehyde is classified by the US Environmental Protection Agency as a potential carcinogen for humans and is considered by the International Agency for Cancer Research (IARC) to be a human carcinogen.

The Sentinel-5P satellite is part of the ambition of the European Union (EU) and the European Space Agency (ESA) to observe the Earth's atmosphere.

Satellites fly at an altitude of 800km, while monitoring the atmosphere to detect events such as volcanic eruptions that could endanger aircraft or ultraviolet rays that are dangerous to the skin.

The data it collects will also be used to understand more about Earth's problems.
