Radio science is a branch of scientific research that focuses on the study of radio waves and the way they interact with the Earth's atmosphere and various objects within it. It encompasses a wide range of topics, including radio wave propagation, atmospheric effects on radio signals, radio frequency interference, and the design and operation of radio communication systems. Radio science is used in a variety of applications, including telecommunications, weather forecasting, navigation, and astronomy. Researchers in this field often use techniques such as radio wave modeling, field measurements, and satellite observations to further our understanding of how radio waves behave in different environments.
