Radio Wave Propagation Forecasting
Forecasting involves short-term estimations of how radio waves will travel through the atmosphere, based on recent measurements.
In contrast, predictions are used to determine the best radio communication frequencies and times more generally. They can also optimize radio coverage and plan antenna systems. Predicting propagation conditions relies on models that consider factors such as signal frequency, time of day, season, sunspot cycle, and ionospheric conditions. However, predictions cannot account for chaotic solar and geomagnetic storms.
