This region extends from about 50 to 300 miles above the Earth's surface, and it overlaps with the thermosphere.
Schumann resonances are confined by Earth's surface and this region, which is home to variability called the diurnal, winter and equatorial anomalies. The satellites AEROS and AEROS B were launched to study this region, which is also studied by the HAARP program. Some of its layers are named for Heaviside and Appleton, but it is more commonly divided into D, E, and F layers. This region extends from about 50 to 300 miles above the Earth's surface, and it overlaps with the thermosphere. For 10 points, name this atmospheric region that is useful for radio transmissions and is named for its large amount of free electrons and positively charged molecules.
