Book Description
The expansion of telecommunication services into the millimeter wave region prompts a careful look at the limitations of the atmosphere that can give rise to severe signal degradations. In Part I the loss and scatter mechanisms in the 10- to 40- GHz range are examined. It is concluded that there is a need for further theoretical and experimental work on the atmospheric propagation properties in order to support the engineering efforts in designing reliable, useful systems. In Part II the discussions are extended to the 40- to 75 -GHz region where absorption by oxygen dominates. In this region, communication through the atmosphere is not practical; however, the oxygen absorption has a great potential for remote sensing of atmospheric variables, and for special (short-range communication) applications. Unsolved problems of the propagation medium are discussed as a basis for formulating proposals; and the objectives of an experimental program for studying oxygen dispersion and absorption are given.

Book Description
Atmospheric attenuation and sky emission measurements at 15, 31, and 53 GHZ are described. Theoretical values of atmospheric absorption and brightness temperatures calculated from radiosonde data are compared with the near-simultaneous experimental measurements. It is concluded that the present theory of gaseous absorption gives estimates of attenuation that are sufficiently accurate for telecommunications design purposes. However, attenuation in clouds requires additional study before optimum use of the higher frequencies can be achieved.
