Ionospheric variations
WebThe plasma analyzer instrument was carefully designed to record the parameters of the thermal population, which are the densities of the main ionospheric ions: hydrogen … WebThe US Air Force Coverage and Analysis Program (AFCAP) experiments 1, 2, and 3 have all been multimillion dollar campaigns to perform detailed Observing System Experiments (OSEs) of the ionosphere. Much of that expense has been dedicated to collecting enough observations of the ionosphere to be capable of post processing a “truth” ionosphere.
