FTP, identify this section of earth's upper atmosphere that is coupled to the magnetosphere and is named for the charged particles that it contains.
It contains an electric field convection area known as the Harang discontinuity. A resonating cavity between it and the surface is occasionally filled by lightning flashes known as Schumann resonances, and between the plasma density maximum and 3000 km altitude can be found the Alfvén resonator. This plasma density maximum starts at about 170 km and, known as the F layer or Appleton layer, reflects radio waves back into the lower atmosphere.
