| Abstract |
Microwave spectrum from atmospheric gases is emitted by rotational transitions. The emitted radiation can be detected from the ground at defined frequencies. The shape and intensity of the spectra are modified during passing through the atmosphere. At the atmosphere, the oxygen and water vapor including liquid water influence on the microwave transfer process. The oxygen concentration in the atmosphere is well known and is stable, but the water vapor concentration changes every moment. The transmission of atmospheric microwave spectrum is also changed by water contents of the atmosphere. In this study, we will determine the atmospheric microwave transmission by using the measured microwave spectra with different path lengths. The transmission is derived from the radiative transfer equation by using three different methods which are called log-fit, least-squares fit, and chopper wheel method. And the derived transmission is also compared to the millimeter propagation model.
