Coupled with the magnetosphere, for 10 points, identify this layer of the atmosphere that contains plasma and is important for radio transmissions.
Project HAARP [harp] involves building a giant namesake heater to change its shape and conductivity. Its height and density were first measured by Lloyd Berekner while Vitaly Ginzburg has proposed theories for electromagnetic wave propagation within it. A natural resonator between it and the terrestrial surface forms the Schumann resonances. Divided into layers known as the D, E, and F layers, other layers include the Heaviside and Appleton.
