The statement that the layer near 10 is a "dust layer" does not conform to the common sense of atmospheric physics. Because at a height of 30 to 40 meters above the ground, the dust will not stop. Dust will not stop in the stratosphere from the ground 10 km to 52 km. In other words, there is no such thing as lime layer in ordinary high-rise buildings. Lime layer is just a statement, which has not been scientifically determined. Not absolutely! !
