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... -
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... -
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... -
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... -
