A propos de cet article

The ionosphere is a region of Earth's upper atmosphere, from about 60 km (37 mi) to 1,000 km (620 mi) altitude, and includes the thermosphere and parts of the mesosphere and exosphere. It is ionized by solar radiation, plays an important part in atmospheric electricity and forms the inner edge of the magnetosphere. It has practical importance because, among other functions, it influences radio propagation to distant places on the Earth Karl Rawer (born April 19, 1913) is a German specialist in radio wave propagation and the ionosphere. He developed the analytical code to determine suitable frequency ranges for short wave communication by which German forces built-up their long distance communications during World War II. After studies of mathematics and physics in Freiburg and Munich (with Arnold Sommerfeld),under Jonathan Zenneck he wrote a thesis on partial reflection of radio waves in an ionospheric layer. Aware of this Johannes Plendl charged him to serve as adviser for the Shortwave communications of the German Luftwaffe, since 1943 for Navy and Army as well. Rawer's code assumes zig-zag paths between Earth and ionosphere. Monthly predictions take account of day-to-day variations. Long term changes from solar cycles is taken account of by Wolfgang Gleissberg's prediction method. After the war Yves Rocard, then director of French Navy research was impressed by Rawer's code. He engaged him as "directeur scientifique" (1946-56) of his newly founded "Service de Prevision Ionospherique". Later (1956-69) Rawer, now serving in Germany as director of "Ionosphoren-Institut Breisach" switched to space research. With his team he participated in the first French scientific rocket launch 1954 in the Sahara desert and later they experimented aboard rockets of different nationality. From 1958 to 1964 he was "professeur associe" at the University of Paris. Rawer held several offices in the international space research organization COSPAR. As director of "Fraunhofer-Institut fur physikalische Weltraumforschung" (1969-79) he became the father of two German/Us satellites (AEROS, 1972 and 1975). He was actively engaged in the International Geophysical Year (gold button 2007) and follow-ups. In the International Union of Radio Science (URSI) he served with William Roy Piggott as co-author of the booklet on ionogram reduction and was vice-chairman and chairman of the ionospheric committee 1966-72. He is the father and longtime chairman of the International Reference Ionosphere that since 1999 is International Standard. Rawer is doctor honoris causa of the university at Dusseldorf, corresponding member of the International Academy of Astronautics and of "Oesterreichische Akademie der Wissenschaften Wien".…
