The F region of the ionosphere is home to the F layer of ionization, also called the Appleton–Barnett layer, after the English physicist Edward Appleton and New Zealand physicist and meteorologist Miles Barnett. As with other ionospheric sectors, 'layer' implies a concentration of plasma, while 'region' is the volume that contains the said layer.
The ionosphere (/ aɪ ˈ ɒ n ə ˌ s f ɪər /) [1] [2] is the ionized part of the upper atmosphere of Earth, from about 48 km (30 mi) to 965 km (600 mi) above sea level, [3] a region that includes the thermosphere and parts of the mesosphere and exosphere.
Together with the (partial) ring current, Region 1 and Region 2 currents form the convection circuit, which is associated with the Dungey cycle. [2] On the day-side, around noon, another type of FAC can be found: Region 0 currents, going into and out of the ionospheric polar cap, the direction of which is decided by the direction of the IMF.

International Reference Ionosphere (IRI) is a common permanent scientific project of the Committee on Space Research (COSPAR) and the International Union of Radio Science (URSI) started 1968/69. It is the international standard empirical model for the terrestrial ionosphere since 1999.
Online grocery prices dipped 0.1% in October from a year — that marks the first dip since January 2020, before the pandemic shuttered the U.S. economy and sent inflation soaring, according to ...
The Gamecocks jumped out to an early 14-0 lead and then scored 10 straight in the third quarter to put the Aggies away. ... The Aggies (7-2, 5-1, SEC) entered the game as just 2.5-point favorites ...
Ionospheric storms are storms which contain varying densities [1] of energised electrons in the ionosphere as produced from the Sun. Ionospheric storms are caused by geomagnetic storms. [2] They are categorised into positive and negative storms, where positive storms have a high density of electrons and negative storms contain a lower density ...
