Abstract
The extension of the practical usage of the radio spectrum to centimeter and millimeter wavelengths is limited by the thermal noise properties of the lower atmosphere. It is the purpose of this paper to outline the theory of tropospheric thermal noise emission, emphasize its dependence upon the absorption and refraction characteristics of the troposphere and, finally, to give estimates of its climatic variation.
