This layer forms the inner edge of the magnetosphere, and it is used to reflect radio waves to remote areas on Earth.
One section of this region was discovered using BBC's Bournemouth transmitter, and it has namesake "sudden disturbances" caused by solar flares. Kennelly and Heaviside predicted a section of this region whose existence was confirmed by Edward (*) Appleton, and this region contains D, E, and F layers. This layer forms the inner edge of the magnetosphere, and it is used to reflect radio waves to remote areas on Earth. This layer contains the upper mesosphere and overlaps with the thermosphere, and its most notable property results from solar radiation. For 10 points, give this layer of the atmosphere so named since it contains charged particles.
