Beverage Dr. Ernst Weber *Member of USNC-URSI Executive Committee iv DESCRIPTION OF THE INTERNATIONAL UNION OF RADIO SCIENCE The International Union of Radio Science is one of 18 world scientific unions organized under the International Council of Scientific Unions (ICSU). It is commonly designated as URSI (from its French name, Union Radio Scientifique Internationale). Its aims are (1) to promote the scientific study of radio communications, (2) to aid and organize radio research requiring cooperation on an international scale and to encourage the discussion and publication of the results, (3) to facilitate agreement upon common methods of measurement and the standardization of measuring instruments, and (4) to stimulate and to coordinate studies of the scientific aspects of telecommunications using electromagnetic waves, guided and unguided. The International Union itself is an organizational framework to aid in promoting these objectives. The actual technical work is largely done by the National Committee in the various countries. The officers of the International Union are: President: W. E. Gordon (USA) Past President: W. N. Christiansen (Australia) Vice Presidents: A. L. Cullen (U.K.) A. P. Mitra (India) S. Okamura (Japan) A. Smolinski (Poland) Secretary-General: J. Van Bladel (Belgium) Honorary Presidents: G. Beynon (U.K.) H. G. Booker (USA) W. Dieminger (West Germany) I. Koga (Japan) J. A. Ratcliffe (U.K.) The Secretary-General's office and the headquarters of the organization are located at Avenue Albert Lancaster 32, B-1180 Brussels, Belgium. The Union is ·supported by contributions (dues) from 38 member countries. Additional funds for symposia and other scientific activities of the Union are provided by ICSU from contributions received for this purpose from UNESCO. The International Union, as of the XXth General Assembly held in Washington, D.C., in August 1981, has nine bodies called Commissions for centralizing studies in the principal technical fields. The names of the Commissions and their chairmen follow. V A. Electromagnetic Metrology V, Kose (FRG) B. Fields and Waves H, G. Unger (FRG) C. Signals and Systems J, K. Wolf (USA) D. Electronic and Optical Devices and Applications J, Le Mizee (France) E. Electromagnetic Noise and Interference S. Lundquist (Sweden) F. Remote Sensing and Wave Propagation D, Gjessing (Norway) G. Ionospheric Radio and Propagation P. Bauer (France) H. Waves in Plasmas M. Petit (France) J, Radio Astronomy V, Radhakrishnan (India) Every three years the International Union holds a meeting called the General Assembly, the next is the XXIst, to be held in Florence, Italy, in August/September, 1984. The Secretariat prepares and distributes the Proceedings of these General Assemblies. The International Union arranges international symposia on specific subjects pertaining to the work of one or several Commissions and also cooperates with other Unions in international symposia on subjects of joint interest. Radio is unique among the fields of scientific work in having a specific adaptability to large-scale international research programs, since many of the phenomena that must be studied are world-wide in extent and yet are in a measure subject to control by experimenters. Exploration of space and the extension of scientific observations to the space environment are dependent on radio for their research. One branch, radio astronomy, involves cosmic phenomena. URSI thus has a distinct field of usefulness in furnishing a meeting ground for the numerous workers in the manifold aspects of radio research; its meetings and committee activities furnish valuable means of promoting research through exchange of ideas. vi Steering Committee S.
