Radio waves in the ionosphere

Caption

Photo of the Earth with radio waves, depicted in purple, flowing across it. HF and VHF waves travel through the ionosphere. But a phenomenon called sporadic-E can interfere with these frequencies. Researchers found that as CO2 levels in our atmosphere rise, sporadic-E may become stronger, occur at lower altitudes, and persist longer at night.
