    Ionograms are recorded tracings of reflected high-frequency radio pulses generated by an ionosonde. Swept-frequency radiowaves transmitted upwards into the ionosphere are reflected at various heights according to well understood processes which are dependent, to a large degree, on the local plasma environment at the reflection point. The frequency and measured time-of-flight for the transmitted and reflected radiowave are used to characterize the layered structure of the ionsphere below the maximum F2 peak. Parameters of typical scientific interest are the heights, local plasma densities, and critical (reflection) frequencies of the F2, F1, and E peaks. Other interested parties include the amateur HAM radio community, emergency management officials, and the military who rely on the ionosphere for long-range radio transmissions at high-frequencies. Ionospheric characteristics can be extracted from an ionogram using manual or computer-automated techniques. Raw ionograms as well as selected ionospheric parameters for the global network of ionosondes are archived by and made available through the World Data Centers.

    Ionograms are recorded tracings of reflected high-frequency radio pulses generated by an ionosonde. Swept-frequency radiowaves transmitted upwards into the ionosphere are reflected at various heights according to well understood processes which are dependent, to a large degree, on the local plasma environment at the reflection point. The frequency and measured time-of-flight for the transmitted and reflected radiowave are used to characterize the layered structure of the ionsphere below the maximum F2 peak. Parameters of typical scientific interest are the heights, local plasma densities, and critical (reflection) frequencies of the F2, F1, and E peaks. Other interested parties include the amateur HAM radio community, emergency management officials, and the military who rely on the ionosphere for long-range radio transmissions at high-frequencies. Ionospheric characteristics can be extracted from an ionogram using manual or computer-automated techniques. Raw ionograms as well as selected ionospheric parameters for the global network of ionosondes are archived by and made available through the World Data Centers.
