This data set, provided by the Radio Research Laboratories (RRL), Tokyo, Japan, consists of RRL reports showing graphs of VLF emission intensity at the satellite. The data set contains data from 304 ISIS 2 passes recorded at Kashima, Japan, during the period 1971 to 1983 and 367 ISIS 2 passes recorded at Syowa, Antarctica, during the period 1979 to 1982. There is one strip chart for each of six frequencies (0.3, 1.5, 5, 8, 16, and 25 kHz) on each page. Intensity is graphed on an arbitrary dB scale vs 5 parameters (satellite altitude, universal and local times, L-shell value at the satellite, and satellite invariant latitude). On the data for the period 1979 to 1983 the upper frequency is 20 kHz instead of 25 kHz, and the geomagnetic latitude is given instead of the L value. This data set was received at NSSDC as unpublished, unnumbered, internal RRL reports titled "Radio and Space Data," v. 1, pt. 3, March 1975; v. 2/3, pt. 3, March 1976; v. 4, pt. 3, March 1977; v.5, pt.3, March 1978; v.6, pt. 3, March 1979; v.7, pt. 3, March 1980; v.8, pt. 3, March 1981; v.9, March 1981; v.10, pt. 3, March 1982; v. 11, pt. 3, March 1983; v. 13, May 1983; v.14, pt. 3, March 1984; v.15, March 1984; and v.16, pt. 3, March 1985. A single copy of these reports is available for use at NSSDC as TRF B25018. On request, individual pages can be copied as required, or a microfiche copy can be supplied.
