A collection of titles and abstracts is presented for articles dealing with the microwave fading that has been observed on tropospheric line of sight paths.Selections are included for related subjects such as:measurement of meteorological factors; spatial, frequency * and time diversity reception; and attenuation due to trees and buildings.Also included is a subject index and an author index.(Author).

A survey of some of the advances in the field of synoptic radio meteorology is presented. The development of representative refractive index profiles for major air mass types is reviewed. Included is a description of several refractive index parameters currently in use by radio meteorologists. Two reduced-to-sea-level index forms developed at the National Bureau of Standards are used to illustrate the three-dimensional structure of a broad-scale storm system traversing the North American continent.
