Electron Density and Temperature

Description

These reduced data, prepared by the experimenter, list about 21 months of electron number densities and electron temperatures observed at the satellite. The data set is on an EBCDIC magnetic tape written on an IBM 360 computer. The data have been calculated from the telemetered retarding potential curves. Included in the listings for each data point are telemetry station, orbit number, date, Greenwich and local mean time, geodetic coordinates, geomagnetic latitude and longitude, invariant latitude, geomagnetic-field intensity and dip angle, solar zenith angle, solar 10.7-cm flux, planetary Ap index, satellite potential, and record count. Temperature data are available for only about 5% of the data points and are scattered throughout the observing period. Electron density values are present at nearly all data points. Gaps in time coverage are usually a few orbits or less. The data have gaps in coverage caused primarily by lack of a tape recorder on the satellite and limitations of experiment scheduling. These same data are available on microfilm as data set SPIO-00021. The data are summarized in data set SPIO-00122.
