What is cn2 in the atmosphere?

Answer 1

CN2 in the atmosphere is not an actuality. The 'C' stands for carbon, but there is no carbon in the atmosphere, carbon is not a gas. N2 stands for nitrogen. There is nitrogen in the air. Perhaps it is CO2 that needs more clarification. CO2 is Carbon Dioxide. There is carbon dioxide in the air because that is what humans give off when they exhale. Plants need this to survive.

Answer 2

CN2 in the atmosphere typically refers to the atmospheric refractivity gradient in meteorology and atmospheric science. It is a measure of how the density of air changes with height, which can affect the propagation of electromagnetic signals, such as radar or radio waves. A higher CN2 value indicates more turbulence in the atmosphere, which can impact the accuracy of weather forecasting and communication systems.
