Electron impact processes in the Earth's ionosphere - Micro-to-macro approach

Quantitative descriptions of fundamental electron impact processes in terms of cross sections are required to understand and model various environments. This includes a variety of electron impact processes in the Earth's ionosphere, atmospheres of planets and their satellites, cometary coma and in plasma processes. Therefore, we have calculated the electron impact ionization cross sections for available neutral gaseous species in these atmospheres. Further, we employ a Micro-to-macro approach to calculate different bulk parameters, i.e. mean free path, collision frequencies etc, of incident electrons in these atmospheres.
