Main gases of the ionosphere (about 50 km; 31 miand above on this chart) vary considerably by altitude. The F layer or region, also known as the Appleton–Barnett layer, extends from about 150 km (93 mi) to more than 500 km (310 mi) above the surface of Earth. It is the layer with the highest electron density, which implies signals penetrating ...
HAARP approaches the study of the ionosphere by following in the footsteps of an ionospheric heater called EISCAT near Tromsø, Norway. There, scientists pioneered exploration of the ionosphere by perturbing it with radio waves in the 2–10 MHz range, and studying how the ionosphere reacts.
Layers of the ionosphere.The Kennelly–Heaviside layer is the E region. The Heaviside layer, [1] [2] sometimes called the Kennelly–Heaviside layer, [3] [4] named after Arthur E. Kennelly and Oliver Heaviside, is a layer of ionised gas occurring roughly between 90km and 150 km (56 and 93 mi) above the ground — one of several layers in the Earth's ionosphere.
The movement of charge between the Earth's surface, the atmosphere, and the ionosphere is known as the global atmospheric electrical circuit. Atmospheric electricity is an interdisciplinary topic with a long history, involving concepts from electrostatics, atmospheric physics, meteorology and Earth science. [2]

A Florida teacher was caught naked inside of an elementary school classroom with sex toys, marijuana and women’s underwear — and punched a cop while trying to flee the scene, according to police.
Fortunately for all of us, @Erin Samples cleared things up, "For everyone concerned, they released him in the Southern Ocean, which is also known as the Antarctic Ocean. He’s where he belongs."
