April 1942: IRPL Publishes First Ionospheric Predictions
In April of 1942, shortly after the U.S. entry into World War II, the Interdepartmental Radio Propagation Laboratory (IRPL) published its first ionospheric predictions. These predictions on the height and state of the ionospheric layer of the Earth’s atmosphere were used to determine which frequencies and paths would be most effective for radio communication. The ionosphere is made up of shifting plasma that reflects radio waves; it is necessary for radio communication in most situations. Knowing the height and state of the atmospheric layer allows more distant communication with reduced interference. IRPL had been sounding the ionosphere with radio waves and reporting their findings since 1 ...
