摘要: Abstract A study is made of the ionization Martian atmosphere below 100 km in context recent data on and ionosphere planet. Suggested sources include: solar ultraviolet X-radiation, cosmic rays, meteors, radioactive material within atmosphere, radioactivity surface, wind, protons originating from flares. Loss processes, including charge rearrangement, dissociative recombination ions electrons, negative ion formation are detailed. Possible importance CO4− discussed. Its distribution will depend O2 content as well O CO. CO− CO3− may also be present ionosphere. It shown that combination photoionization rate with due to radiation lead an density minimum. The magnitude location minimum atmospheric model chosen, activity, zenith angle such factors presence particulate matter meteor ionization.
