RRS Electron Density Values at 10-KM Intervals on Microfiche


Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1962-11-26 to 1963-07-31


This data set, provided by the Radio Research Station (RRS), Slough, U.K., consists of 3 volumes of electron density profiles for the ionosphere above the F2 maximum (topside ionosphere). This data set is on microfiche. The profiles were computed from digital values of frequency and virtual height, which had in turn been scaled from the ionograms. This data set contains profiles from eight passes (254 profiles) over Singapore, and profiles from four passes (123 profiles) over Pt. Stanley, Falkland Islands. The electron densities are given at 10-km geodetic-height intervals and at 20-km geopotential-height intervals. The electron density vs geopotential height is also shown as plots. This microfiche data set was prepared at NSSDC from unpublished, unnumbered internal RRS reports titled "Height distribution of electron concentration in the topside ionosphere as deduced from topside sounder satellite ionograms." v. 1, December 1963; v. 2, December 1964; and v. 3, January 1965. A single copy of these reports is available for use at NSSDC as TRF B20806. On request, individual pages can be copied as required or the microfiche copy can be supplied.
