“…We can then ask what the character of the RF noise distribution is as seen by a fixed observer. This problem has been treated for the case of the earth and distributed lightning sources by several workers [e.g., Watt and Maxwell, 1957a, b;Volland, 1966Volland, , 1974Frisius and Heydt, 1970;Bart, 1970].…”

The Galileo satellite program includes the delivery of an entry probe to the Jovian equatorial atmosphere in mid‐1985. Optical and RF sensors for a lightning detection system are included as a part of the probe experimental payload. In this paper we present calculations of the RF wave propagation and reflection characteristics of the equatorial Jovian atmosphere and ionosphere for frequencies less than 100 kHz. We show that the wave propagation is limited to line‐of‐sight and one‐hop from the ionosphere. We also present results of a statistical treatment of the RF wave power densities for the case of a finite number of events and for the case of a uniformly distributed source. The results can be applied to specific RF experiment configurations concerned with establishing the statistical characteristics of Jovian lightning.

“…[Heydt, 1971]. These parameters allow a determination of the distance to the source by applying appropriate propagation models [Volland, 1968;Frisius et al, 1970;Harth, 1972]. These data are recorded on strips and are available only for selected observation periods.…”

Measurements of VLF atmospherics taken atSan Miguel, Argentina, are presented. Results from one 13-year measurement period (1956-1969) as well as one 2-year interval (1971-1973) are used to document the morphology of the diurnal and annual variations in atmospherics activity at San Miguel. The atmospherics rates obtained during the second interval, which may be ordered according to arrival azimuth, show that most of the activity originates in thunderstorm cells located NE and NW of the observation station. Distance determinations from the dispersion of the atmospherics impulses, together with an estimate of the instrument's range, indicate that these activity cells lie primarily over the South American continent. Additional measurements of atmospherics activity taken in Berlin from 1971 to 1975 are also shown, from which a certain trend in the activity in the South American sector may be inferred. Both the Berlin and San Miguel records indicate a decline in atmospherics activity over the measurement period.
