This data set consists of all the electron content observations for which complete data reduction was possible, as contained in R. B. Fritz and J. K. Hargreaves, "Measurements of Ionospheric and Exospheric Electron Content Using Radio Beacons on Orbiting Geophysical Observatories," Compilation of Data and Final Report, Space Environment Laboratory, ERL-NOAA, Boulder, CO, December 1973 (TRF B18548), on microfiche. The data set comprises 28 of the 62 orbits from which observations were taken. The data for each orbit are on two frames of microfiche. One frame contains spacecraft time and position information along with Kp and electron density at the F2 maximum (from the Boulder ionosonde). The other frame contains a plot of the following four quantities vs time (GMT): I(F), the total electron content from Faraday rotation techniques; I(F) (V), I(F) normalized to a vertical path through the F1 maximum; I(P), the value of the phase measurements (relative to I(F) since absolute values were not obtained); and I(X), I(P) minus I(F). Discussion and background information are also contained in this data set.
