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".

In fact, the equipment provides a record of the time derivative of the element in question. 6) Records of the time derivatives of magnetic elements can, however, be obtained in a more direct way by recording directly the electromotive force (e. m. f. ) induced in suitably disposed coils by the variations of the geomagnetic field 10, 11. When a coil with the total winding area F is placed with its axis in the direction of a geomagnetic force component the variation of magnetic induction B with time will produce an electromotive force 1 dB 1 dH e=- coveu, uuFdT=- 'oV, uQf1oFdT (i). )) . ! . =_to-13 d(B/y) (1). )a) v em! d(tjs) in the coil. The e. mJ. may be amplified and recorded by means of an oscillograph or on a tape recorder. but more often the coil is used in connection with an ordinary galvanometer and the scale value of, for instance the dl1/dt record, will then - in the same way as the scale value of the magnet variometer treated in Subsect. IX - be dependent on the damping factor IX and on TO/T, where To and T are the oscillation periods for the undamped galvanometer and for the magnetic pulsation respectively. The amplitude recorded will be proportional to the amplification factor I, obtained from Eq. (1).Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 2516 pp. Englisch.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - 83 input to the ions is balanced by a cooling to atomic oxygen, the major neutral constituent, and measurements of the difference between ion and neutral tem perature permit the determination of atomic oxygen concentrations. Using this approach, ALCA YDE et al. 6 have shown from data taken above Saint Santin, France, that the atomic oxygen concentration at 200 km is slightly larger in winter than summer. () The molecular concentrations at heights near 200 km can also be derived from a determination of the ratio of the molecular-ion concentration to elec tron concentration, p (Cox and EVANS 7). It can be shown from the steady state form of the continuity equation for 0+ ions that (20.2) where Q(O+) represents the photoionization coefficient of oxygen atoms, and k and k19 represent the rate coefficients of reactions between 0+ ions and 1S molecular nitrogen Illld oxygen (reactions (12.18) and (12.19)). Then the ratio of atomic oxygen to weighted molecular sum is given by: (l-p)Ne [OJ (20.3) Q(O+) , [kMJ where Ne represents the electron concentration.
