Abstract : The purpose of the work relating to this report is to study the propagation characteristics of millimeter waves in the earth's atmosphere. One method used to accomplish this was to make measurements of the radiation of the sun and atmosphere together, and the atmosphere alone. These measurements were made with a 36 GHz radiometer. Other methods were to reduce and analyze data supplied by the technical monitor and develop some related theoretical ideas. A variety of absorption and emission statistics of the atmosphere have been acquired at 36 GHz. From these data certain propagation characteristics have been specified, some of these relate to meteorological factors. Certain solutions and possible solutions were suggested for the data problems supplied by the technical monitor. Specific theoretical ideas were developed for future use in investigations. (Author)
