noun
- An instrument that measures the properties of the ionosphere by transmitting radio waves and analyzing their reflections.
Usage: technical; used in atmospheric science and radio physics
Examples
- The ionosonde detected changes in the ionosphere during the solar storm.
- Scientists use ionosondes to monitor the critical frequency of radio waves.
- The network of ionosondes provides real-time data on ionospheric conditions.
- An ionosonde transmits pulses at different frequencies to map the electron density profile.
- The ionosonde's measurements help predict radio propagation patterns.
