Hourly Values of Reduced Total Electron Content Data

Description

This data set consists of digitized hourly values of total electron content through the ionosphere and the solar wind. These are reduced data calculated from measurements of the differential delay of the group velocity of signals from earth to the spacecraft. The hourly data are representative values manually selected from analog records. Each set of hourly values is for the portion of the day (about 12 h per day) when the spacecraft was in view from the Stanford transmitter. This data set is on one BCD magnetic tape generated at NSSDC from punched cards supplied by the experimenter. The tape also contains identical data for other time periods from Pioneers 7 (66-075A-04A), 8 (67-123A-03A), and 9 (68-100A-03A), and Mariner 5 (67-060A-02A).
