GENERAL BIBLIOGRAPHY OF REPORTS ON 



TROPOSPHERIC PROPAGATION 



REPORT WPG-14 



This Bibliography is a comprehensive tabulation of the body of scientific reports pertaining to wave propagation through 

 the troposphere, compiled by the Columbia University Wave Propagation Group to about October 31, 1945. For convenience 

 and clarity it has been divided into twenty sections, each dealing with a particular phase of propagation phenomena. The 

 various headings are self-explanatory, and the list of sources and their abbreviated designations which precede the Bib- 

 liography proper will be found helpful. 



In preparing the Bibliography, about 560 papers were considered. Of these, 115 were excluded as obsolete, or because their 

 contents were included in other reports retained. An additional 46 papers dealing with doppler effect and the transmission 

 of sound in water were also excluded as not directly relevant. It is believed that the approximately 400 titles included form 

 a fairly exhaustive compilation of present knowledge of electromagnetic wave propagation through the troposphere. 



The reports are grouped and a Bibliography number has been assigned to each report. The letter to the right of the Bibliog- 

 raphy number designates the present United States security classification. 



Requests for copies of the reports listed herein may be made by Bibliography number referring to this edition, but should 

 be made through the proper channels. The Central Radio Bureau is the distributing agent for American reports in Great 

 Britain and for propagation reports originating in Great Baddow, Chelmsford, England. All other British reports may be ob- 

 tained from the British government department controlling the sources. 



The OSRD Liaison Office will, upon request, supply readers in the United States who are not in the Armed Services with 

 all reports originating outside of the United States. They will supply Army and Navy units with all except JEIA-numbered 

 reports. Requests for the latter should be directed to the Joint Electronics Information Agency, Munitions Building, Wash- 

 ington, D.C. 



In general, application should be made to the NDRC Chairman's Office for reports written by NDRC Divisions, Committees, 

 or contractors, NDRC Section 6.1 being the present exception; to the Bureau of Ships for reports from Naval Research Lab- 

 orator)', Navy Radio and Sound Laboratory, and all reports appearing in Section 20 of the Bibliography (Under- Water Sound 

 Propagation) ; to the Office of the Chief Signal Officer for Signal Corps reports; to Inter-Service Radio Propagation Laboratory, 

 Bureau of Standards for IRPL reports. Requests for case-numbered BTL reports should be sent to the Director of Research, 

 Bell Telephone Laboratories, 463 West Street, New York, N. Y.
