Radio occultation

Radio occultation is a way of measuring the properties of Earth's atmosphere by sending radio waves to a satellite. When the waves reach the satellite, some of them pass through Earth’s atmosphere where they get bent by its layers of air because the air has different temperatures and densities. By measuring how much the radio waves get bent, we can figure out what the temperature and pressure of the atmosphere is like. This information can then be used to help us better understand the atmosphere and how it affects weather patterns.
