WebStatistical maps of F region Joule heating in the northern hemisphere polar ionosphere are derived from satellite measurements of thermospheric wind and radar measurements of ionospheric ion ... WebSAMI3 is based on SAMI2 (Huba et al., 2000), a two-dimensional model of the ionosphere. SAMI3 models the plasma and chemical evolution of seven ion species (H+, He+, N+, O+, N2+, NO+ and O2+) in the altitude range extending from 70 km to ~8 Re (Earth radii) and magnetic latitudes up to ±88°. SAMI3 solves the ion continuity and momentum ...
