Latitude Versus Total Electron Content Over Illinois, Michigan and Montana, Mfche


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

Time span: 1964-10-21 to 1965-03-17


These data have been reduced to units of electron number density per unit of cross section for a vertical path through the ionospheric point. Analysis consists of plotting data for each hour of each season, on one graph. Data for all four seasons for most hours are available for Urbana, Illinois. Spring and summer data for most hours are available for Bozeman, Montana, and Houghton, Michigan. One or more passes, labeled with date and time, appear on each plot. These plots were prepared by satellite program participants and are contained in appendix B of "Latitude Dependence of Ionospheric Electron Content," by Weise and Yeh, and in "Study of Ionospheric Electron Content from Observations at Different Stations," by Youakim and Rao.
