Electron Density Profile Data Contains Virtual Height/Frequency Pairs from a Profile or Profiles (Composite Months) of Ionograms

The Electron Density Profile, N(h), data set contains both individual profiles and composite months. The data consist of virtual height/frequency pairs from a profile or profiles (composite months) of ionograms. Data includes the station, year, month and hour (or composite month) for each record. Data are available on 9-track magnetic tape. Electron density profiles are also available in Dataset_ID: G10145. The stations included are Argentia, Bermuda, College, Dyess, Goose Bay, Narssarssuaq, Puerto Rico, Sondestrom, Thule, and Wallops Island.
