RESEARCH ON IONOSPHERIC STRUCTURE AND MOTION.

Abstract

Individual fades observed with six antennae are reduced for different combinations of three of them. The differences between drift vectors so found are statistically analyzed. The normal case is not a plane but a curved front (radius down to 100 m). A descriptive interpretation is given by out- and ingoing curved fronts (sources and sinks ). When a prevailing drift is present the basic form of the extremal lines is elliptical. Statistics shows an average axis ratio 2 : 1 with more sinks than sources. Five years of dense observations prove solar and lunar tides to be rather different for low and high declination. An automatic drift-measuring apparatus based on crosscorrelation technique is described. (Author)
