摘要: Empirical models of molecular ion densities (N2 +, NO+, O2 +) and the electron density (N e ) are presented in altitude interval 50–4000 km as functions time (diurnal, annual), space (position, altitude) solar flux (F 10.7). Using observations 6 satellites (AE-C, AE-D, AE-E, ALOUETTE-2, ISIS-1, ISIS-2), 4 incoherent scatter stations (Arecibo, Jicamarca, Millstone Hill, St Santin) more than 700 D-region profiles, this model describes global gross features ionosphere for quiet geophysical conditions (K p ≦ 3). The increase with increasing up to a maximum (or several maxima) - decrease from thereon height. Between ~80 200 km, main ionic constituents NO+ O2 +; below cluster ions predominating. During local summer N around polar latitudes correspondingly during winter. diurnal variations intrinsically coupled individual plasma layers; general, enhanced daytime depleted nighttime (for details exceptions, see text).
