Ionosonde Stations
Ionograms are recorded tracings of reflected high frequency radio pulses generated by an ionosonde. Unique relationships exist between the sounding frequency and the ionization... -
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... -
Worldwide Hourly Values of Ionospheric Characteristics: foF2, M(3000)F2, hF2,FoF1, M(3000)F1, hF, FoE, hE, foE2, hE2, foEs, fbEs, fmI, and FxI
The ionosphere is that part of the Earth's atmosphere that results mainly from the ionizing effect of Solar electromagnetic radiation. For poleware latitudes, the ionizing... -
Ionospheric Values (Daily Work Sheets), F-Plots, Tabulations, Booklets, Catalogs, and Log Books
These ionospheric data consist of scaling notes, equipment usage logs, and ionospheric values in the form of daily work sheets, F-Plots, tabulations, and booklets. The station... -

Ionospheric Digital Database
The ionosphere is that part of the Earth's atmosphere that results mainly from the photo ionization of the upper atmosphere. Traditionally, the following ionospheric regions and... -
Scaled Data from Digital Ionograms
All the data contributed come from 1957 through 1990. They have been digitized, reformatted, converted to universal time (the software also can display the data in local... -
Photographic Records Showing the Variations of the Virtual Height of Reflection as a Function of the Radio Frequency
The standard (analog) ionosonde produces photographic records known as ionograms, which show the variations of the virtual height of reflection as a function of the radio...
