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 ...

In another test, ionised gas in the atmosphere increased in heat by 100 degrees Celsius (212 degrees Fahrenheit). An ionospheric heater, or an ionospheric HF pump facility, is a powerful radio wave transmitter with an array of antennas which is used for research of plasma turbulence, the ionosphere and upper atmosphere. These transmitters operate in the high frequency (HF) range (3-30 MHz) at which radio waves are reflected from the ionosphere back to the ground. With such facilities a range of plasma turbulence phenomena can be excited in a semi-controlled fashion from the gr…
