Who has a simulated structure of the earth's atmosphere and wants pictures?
Stratosphere: the atmosphere about 10 ~ 50km away from the earth's surface, located above the troposphere and below the escape layer. It is a layer of the earth's atmosphere that is hot at the top and cold at the bottom.
Mesosphere: from the top of the stratosphere to the atmosphere of 85 kilometers. The vertical temperature drop rate of this layer is very large, and the convection movement is strong. The temperature near the middle roof is about 190K.
Thermosphere: also known as warm layer, located above the middle layer and below the escape layer, with the top about 800km from the ground. The air in the thermosphere is highly ionized by solar short-wave radiation, and the ionosphere exists in this layer, and the aurora also occurs at the top of the thermosphere.
Escape layer: also known as the outer layer, it is the outermost layer of the earth's atmosphere from 800km to 2000-3000km from the surface. The air in the escape layer is extremely thin, its density is almost the same as that in space, and the temperature rises slightly with the increase of height.
Extended data atmosphere is a layer of mixed gas formed around the earth due to gravity, which is the outermost gas layer of the earth, surrounding the ocean and land. There is no exact upper limit of the atmosphere, and there are still thin gases and elementary particles at a height of 2000~ 16000 km from the surface.
Underground, there is also a small amount of gas in soil and some rocks, which can also be considered as a part of the atmosphere. The main components of the earth's atmosphere are nitrogen, oxygen, argon, carbon dioxide and trace gases with a proportion less than 0.04%. These mixed gases are called air.
