摘要: Daytime positive ion densities calculated using recently measured laboratory ion-neutral reaction rate constants are compared with the NRL rocket results between 120 and 220 km. The O+ N2+ found to be in good agreement ionospheric observations. main loss process this region is reaction This also major source of NO+ at 140 charge-transfer reaction appears a significant km indeed may source. reaction will if ratio atomic molecular nitrogen as large 10−4. fast O2+ NO night requires local ionization greater than 1 ion/cc sec maintain observed concentration.
